The Checkout SDK is a JavaScript library provided by Ottu that allows you to easily integrate an Ottu-powered checkout process into your web application. With the Checkout SDK, you can customize the look and feel of your checkout process, as well as which forms of payment are accepted.
To use the Checkout SDK, you'll need to include the library in your web application and initialize it with your Ottu merchant_id, session_id, and API key. You can also specify additional options such as, which forms of payment to accept, the theme styling for the checkout interface, and more.
Please note that the Checkout SDK requires the implementation of the Checkout API in order to function properly.
For optimal security, call REST APIs from server-side implementations, not client-side applications such as mobile apps or web browsers.
Below is a demo of the Checkout SDK in action. This demo shows how the Checkout SDK can be used to create a streamlined checkout experience for customers, with support for multiple forms of payment and a customizable interface.
To install the Checkout SDK, you'll need to include the library in your web application by adding a script tag to your HTML section. You can do this by using the following code snippet:
Replace errorCallback, cancelCallback, successCallback, and beforePayment with the names of your error handling, cancel handling, success handling, and beforePayment handling functions, respectively.
You're all set! You can now use the Checkout SDK to create a checkout form on your web page and process payments through Ottu.
Is the function that initializes the checkout process and sets up the necessary configuration options for the Checkout SDK. It needs to be called once on your web page to initialize the checkout process, and it must be called with a configuration object that includes all the necessary options for the checkout process.
When you call Checkout.init, the SDK will take care of setting up the necessary components for the checkout process, such as creating a form for the customer to enter their payment details, and handling communication with Ottu's servers to process the payment.
The Checkout.reload function in the Checkout SDK is used to refresh the SDK. It's useful when you want to reload the content of the SDK after an error has occurred or when the content needs to be refreshed.
Here's an example of how Checkout.reload might be called:
stringThe selector property in the Checkout SDK is used to specify the css selector for the HTML element that will contain the checkout form. This is typically a <div> element on your web page.
To specify the selector, you can add a <div> element to your web page with a unique id attribute, like this:
It's important to note that the selector property must be the ID of the HTML element that will contain the checkout form. This is because the Checkout SDK replaces the contents of the specified element with the checkout elements.
Here's an example of how Checkout.init might be called with a selector property:
stringThe merchant_id specifies your Ottu merchant domain. This should be the root domain of your Ottu account, without the "https://" or "http://" prefix.
For example, if your Ottu URL is https://example.ottu.com, then your merchant_id is example.ottu.com. This property is used to identify which Ottu merchant account the checkout process should be linked to.
stringThe apiKey is your Ottu API public key. This key is used for authentication purposes when communicating with Ottu's servers during the checkout process.
According to the REST API documentation, the apiKey property should be set to your Ottu API public key.
Ensure that you utilize the public key and refrain from using the private key. The private key should remain confidential at all times and must not be shared with any clients.
stringThe session_id is the unique identifier for the payment transaction associated with the checkout process.
This unique identifier is automatically generated when the payment transaction is created. For more information on how to use the session_id parameter in the Checkout API, see session_id.
stringThe lang property serves to designate the language for presenting the checkout elements. You can configure this property with either en for English or ar for Arabic. When lang is configured as en, the checkout form will appear in English, and if set to ar, the checkout elements will be shown in Arabic. Moreover, when the lang parameter is set to ar, the layout will adapt to a right-to-left (RTL) orientation to suit Arabic script.
For seamless user experience, it's recommended to maintain consistency by passing the same value for lang in Checkout.init used in Checkout API while creating transactions.
For more information on how to use lang parameter in the Checkout API, please refer to language parameter in Checkout API section.
arrayformsOfPayment allows you to customize which forms of payment will be displayed in your checkout process. By default, all forms of payment are configured.
The available options for formsOfPayment are:
applePay: The Apple Pay payment method that allows customers to make purchases using their Apple Pay-enabled devices.
googlePay: The Google Pay payment method that allows customers to make purchases using their Google wallet cards linked in google accounts.
ottuPG: A method that redirects customers to a page where customers enter their credit or debit card details to make a payment.
tokenPay: A payment method that uses tokenization to securely store and process customers' payment information.
redirect: A method where customers are redirected to a payment gateway or a third-party payment processor to complete their payment.
stcPay: A method where customers enter their mobile number and provide an OTP send to their mobile number to complete their payment.
urPay: A method where customers enter their mobile number and provide an OTP send to their mobile number to complete their payment.
stringThere are two display Modes i.e grid & column.The Default displayMode is column. Here's an example of how Checkout.init might be called to customize the displayMode
objectThe setupPreload feature is designed to optimize the SDK loading experience by allowing merchants to pre-fetch transaction details and pass them to the SDK during initialization. This eliminates the need for the SDK to make an API call, resulting in faster rendering of the UI.
To utilize the setupPreload feature, include it as a property when calling checkout.init(). The setupPreload object should contain the prefetched transaction details.
The setupPreload functionality relies heavily on the Checkout API. When calling the create or update operation of a payment transaction (using the session_id), set the include_sdk_setup_preload flag to true. This action will prompt the API to return the sdk_setup_preload_payload key, along with other values. Pass this value into the Checkout.init() just as you pass the session_id, ensuring no modifications are made to it.
For more information on how to use the setupPreload parameter, see sdk_setup_preload_payload in the Checkout API.
If the setupPreload object passed during SDKinitialization is not valid or does not adhere to the required structure, the SDK will discard it and automatically fall back to its previous functionality. In such cases, the SDK will initiate an API call to fetch the necessary transaction details from the backend. It is essential to ensure that the setupPreload object follows the specified format to leverage the instant loading feature effectively and avoid fallback scenarios and ensure a seamless integration.

Example
HTML
Javascript
Is a function that shows a message in a popup on the screen. The message parameter must be a string, and the optional pg_response parameter is an object that displays key-value pairs representing object values within the popup.
Popup will not display null values passed in the response.
typestring
he type identifies the modal that should be displayed to the customer. Supported values are error, success&redirect
message string
The message for a failed payment can be displayed to the customer.
pg_response object
The raw response data that was received directly from the payment gateway after the transaction attempt. This typically includes transaction status, transaction identifier, and potentially error messages or additional data provided by the gateway. pg_response is only supported by type error& success
Checkout.showPopup("success","Payment Successful! Redirecting you now. Please hold on.")
Checkout.showPopup(‘error’,'Selected payment method failed. Try again.' , { "merchant":"009057332", "timeOfLastUpdate":"2023-08-01T14:19:00.510Z", "version":"65" })
Checkout.showPopup(‘redirect’,’Redirecting to the payment page’)
In the Checkout SDK, callback functions play a vital role in providing real-time updates on the status of payment transactions. Callbacks enhance the user experience by enabling seamless and efficient handling of various payment scenarios, such as errors, successful payments, and cancellations.
Please note that due to technical constraints associated with off-site redirection during the payment process, the successCallback and cancelCallback functions are only called for on-site checkouts. However, the errorCallback function is called for any kind of payments. On-site checkouts include options such as Apple Pay, Google Pay, payments with saved cards, and on-site card form transactions, which support callback functionality for a seamless user experience.
The errorCallback is a callback function that is invoked when issues arise during a payment. It is important to handle errors appropriately to ensure a smooth user experience. The recommended best practice in case of an error is to restart the checkout process by creating a new session_id using the Checkout API.
To define the errorCallback function, you can use the data-error attribute on the Checkout script tag to specify a global function that will handle errors. If an error occurs during a payment, the errorCallback function will be invoked with a data object with a data.status value of error
Params Available in Data Object for errorCallback
message required
form_of_payment required
status required
challenge_occurred
session_id
order_no
reference_number
Here's an example of how errorCallback might be defined
In this example, the errorCallback function is defined and passed as the value of the data-error attribute on the Checkout script tag. If an error occurs during a payment, the function will be invoked with a data object. This function will handle error as need and show error modal using Checkout.showPopup().
errorCallback function is not required to perform a redirection. It can handle errors in any way that is appropriate for your application.
The cancelCallback in the Checkout SDK is a callback function that is invoked when a payment is canceled. To define the cancelCallback function, you can use the data-cancel attribute on the Checkout script tag to specify a global function that will handle cancellations. If a customer cancels a payment, the cancelCallback function will be invoked with a data object.with a data.status value of "canceled”
Params Available in Data Object for cancelCallback
message
form_of_payment
challenge_occurred
session_id
status
order_no
reference_number
payment_gateway_info
Here's an example of how cancelCallback might be defined
In this example, the cancelCallback function is defined and passed as the value of the data-cancel attribute on the Checkout script tag. If a customer cancels a payment, the function will be invoked with a data object containing information about the cancelled transaction. This function will handle cancellation as needed and show error modal using Checkout.showPopup().
In the Checkout SDK, the successCallback is a function triggered upon successful completion of the payment process. This callback receives a data object,with a data.status value of success
Params Available in Data Object for successCallback
message
form_of_payment
challenge_occurred
session_id
status
order_no
reference_number
redirect_url
payment_gateway_info
The successCallback function is defined and passed as the value of the data-success attribute on the Checkout script tag. If the payment process completes successfully, the function will be invoked with a data object containing information about the completed transaction. The function will then redirect the customer to the specified redirect_url using window.location.href.
Here's an example of how successCallback might be defined
To ensure the integrity of your transactions, the Checkout SDK provides a beforePayment hook that allows you to take necessary precautions before the payment process starts. It's crucial for e-commerce platforms to implement this feature, especially when considering multi-tab operations by users.
Initialize the Hook
When initializing the SDK, you can set up the beforePayment hook which will trigger when the payment process starts.. This hook should return a Promise. If the Promise is resolved, the user may continue with the payment process. However, if the Promise is rejected, the payment process will be halted, and an error message will appear in the browser console.
For wallet payments such as ApplePay, GooglePay, and STCPay, the respective payment sheet will be presented. As soon as the payment process begins, the SDK will invoke the beforePayment hook.
For other payment methods, including redirect, ottuPG, and tokenPay, the beforePayment hook is triggered when the Pay button is clicked
Params Available in Data Object for beforePayment
redirect_url
Handle Payment Outcomes
Success: Direct users to the payment success page.
Cancel/Error: It's essential to unfreeze the cart to allow the user to make changes and retry the payment. Use the cancelCallback and errorCallback provided by the SDK to handle these cases.
Always freeze cart updates during ongoing payment processes. This ensures users can't manipulate cart contents in parallel with a transaction, preserving transaction integrity.
Ensure that the cart is unfrozen in cases of payment cancellations or errors. This improves user experience, allowing them to adjust their cart if needed.
The data object received by the errorCallback, cancelCallback and successCallback contains information related to the payment transaction, such as the status of the payment process, the session_id generated for the transaction, any error message associated with the payment, and more. This information can be used to handle the payment process and take appropriate actions based on the status of the transaction.
stringIt is a string message that can be displayed to the customer. It provides a customer-friendly message regarding the status of the payment transaction.
stringIt is a unique identifier generated when a payment transaction is created. It is used to associate a payment transaction with the checkout process. You can find the session_id in the response of the Checkout API's session_id endpoint. This parameter is required to initialize the Checkout SDK.
stringIt is of the checkout process. Possible values are:
success: The customer was charged successfully, and they can be redirected to a success page or display a success message.
canceled: The payment was either canceled by the customer or rejected by the payment gateway for some reason. When a payment is canceled, it's typically not necessary to create a new payment transaction, and the same session_id can be reused to initiate the Checkout SDK and allow the customer to try again. By reusing the same session_id, the customer can resume the checkout process without having to re-enter their payment information or start over from the beginning.
error: An error occurred during the payment process, This can happen for a variety of reasons, such as a network failure or a problem with the payment gateway's system. The recommended action is to create a new payment transaction using the Checkout API and restart the checkout process.
URLThe URL where the customer will be redirected after the payment stage only if the webhook URL returns a success status. order_no, reference_number and session_id will be appended to the redirect URL as query parameters. The developer implementing the SDK must ensure that the redirection process is smooth and secure, providing a seamless experience for the customer while maintaining the integrity of the payment process.
It's important to note that while the redirect_url option is typically present only in the successCallback, there are specific cases where it may exist in failure scenarios.
For example, in the event of an MPGS cancel or if the transaction includes a webhook URL alongside a redirect URL, users may be redirected after cancellation, which is communicated to the webhook. Therefore, the presence of redirect_url in such cases is possible.
stringThe order number provided in the Checkout API. See Checkout API & order_no.
stringA unique identifier associated with the payment process. It is sent to the payment gateway as a unique reference and can be used for reconciliation purposes.
stringEnum: apple_pay, google_pay, token_pay, stc_pay , redirect
Indicates the form of payment used to process the transaction. This can be one of several options, including apple_pay, google_pay, token_pay, stc_pay, or redirect. It's important to note that the redirect option is only present in the errorCallback. In other scenarios, especially with cancelCallback and successCallback, it's absent. This is because, in the redirect flow, the customer is redirected to a different page where actions like payment cancellation or confirmation occur, not on the page where the SDK is displayed.
apple_pay - Apple Pay
google_pay - Google Pay
token_pay - Token Pay
stc_pay - stc pay
redirect - Redirect
objectInformation about the payment gateway, accompanied by the response received from the payment gateway
stringThe unique identifier, or pg_code, for the payment gateway that was used to process the payment. This value corresponds to the specific payment method utilized by the customer, such as credit-card.
stringThe name of the payment gateway, represented in all lowercase letters, that was used to perform the payment. This could be one of several values, such as kpay (for KNET), mpgs, or cybersource. These identifiers provide a human-readable way to understand the payment mechanism that was utilized.
objectThe raw response data that was received directly from the payment gateway after the transaction attempt. This typically includes transaction status, transaction identifier, and potentially error messages or additional data provided by the gateway.
boolDefault: false
This flag indicates if an additional verification, such as 3DS, OTP, PIN, etc., was initiated during the payment process. Use this flag in cancelCallback and errorCallback to control the presentation of error messages, especially for on-site payments undergoing a challenge flow. For example, after a failed 3DS verification, it's useful to show a custom popup informing the user of the payment failure. However, it's crucial to note that not all on-site failed payments need custom error messaging. In cases like GooglePay or ApplePay, error messages are inherently handled by the Payment Sheet, which remains open for the user to retry, making this distinction vital.
Checkout init function
If you have completed the Apple Pay integration between Ottu and Apple, the Checkout SDK will automatically make the necessary checks to display the Apple Pay button.
When you initialize the Checkout SDK with your session_id and payment gateway codes, the SDK will automatically verify the following conditions:
When initializing the Checkout SDK, a session_id with a pg_codes that was associated with the Apple Pay Payment Service was supplied.
The customer has an Apple device that supports Apple Pay payments.
The browser being used supports Apple Pay.
The customer has a wallet configured on their Apple Pay device.
If all of these conditions are met, the Apple Pay button will be displayed and available for use in your checkout flow. If the wallet is not configured, the Apple Pay button will still appear.Clicking on the button Apple Pay wallet on their device will open, allowing them to configure it and add payment cards.
By default, the type of the Apple Pay button is pay, which is used to initiate a payment. However, you can override the default button type using the applePayInit property of the Checkout SDK.
If you're using only the Apple Pay button from the Checkout SDK and wish to customize its appearance, it's vital to adhere to the Apple Pay guidelines to ensure your design aligns with Apple's specifications. Note that the SDK uses default styles outlined in the guidelines. Using styles not supported by Apple, such as certain background-colors or border-colors, will not take effect. Failure to comply with these guidelines could lead to your app being rejected or even a ban on your developer account by Apple.
It's the responsibility of the merchant to ensure that their use of the Apple Pay button follows Apple's guidelines, and Ottu cannot be held responsible for any issues that arise from non-compliance. If you have any questions or concerns about using the Apple Pay button, please consult the Apple Pay guidelines or contact Apple directly for assistance.
If you only want to use Apple Pay with the Ottu Checkout SDK and control the other payment methods yourself, you can customize the Apple Pay button using the Checkout SDK's formsOfPayment, applePayInit and theme properties.
Properties like buttonColor, buttonType and css properties like height, width, margin etc are can be customized using theme while buttonLocale can be customized using ApplePayInit
To display only the Apple Pay button with default css, use the following code:
The formsOfPayment property tells the Checkout SDK to render only the Apple Pay button. If you don't include this property, the SDK will render all available payment options.
To customize the Apple Pay button's appearance, you can use the theme property. The example below adjusts the size of the button and centers it within the Checkout SDK container:
The Apple Pay button inside the Checkout SDK container can be customized using the theme property by defining the following:
theme.applePay: This class sets the width,height, margin, and padding of the button.
theme.applePay.buttonType: This determines the type of the Apple Pay button.
For example, setting buttonType:
plain will render a plain Apple Pay button.
buy or donate will render buttons with the corresponding labels.
theme.applePay.buttonColor: This determines the color of the Apple Pay button.
For example, setting buttonColor:
black will render a black Apple Pay button.
white or white-outline will render buttons with the corresponding colors.
By default, the width of the Apple Pay button is 100% of the Checkout SDK container width, gap of 8px from other buttons. The Checkout SDK creates a containerized div with the css class ottu__sdk-main and places the Apple Pay button inside it. This container has no margin or padding added, as shown in below figure. To learn more about the applePay property, see the theme.
If you have completed the Google Pay integration between Ottu and Google Pay, the Checkout SDK will handle the necessary checks to display the Google Pay button seamlessly.
When you initialize the Checkout SDK with your session_id and payment gateway codes pg_codes , the SDK will automatically verify the following conditions:
The session_id and pg_codes provided during SDK initialization must be associated with the Google Pay Payment Service. This ensures that the Google Pay option is available for the customer to choose as a payment method.
Web SDK checks if the merchant configuration for Google Pay is correct or not and then show Google Pay button based on it.
The Web SDK displays the Google Pay button irrespective of whether the customer's Google Pay wallet is configured. When the customer clicks the button, they are prompted to log in with their email and add their card if their wallet is not set up.
Google Pay configuration is controlled by using googlePayInit object.
If you're using only the Google Pay button from the Checkout SDK and wish to customize its appearance, it's vital to adhere to the Google Pay guidelines to ensure your design aligns with Google's specifications. Note that the SDK uses default styles outlined in the guidelines. Using styles not supported by Google, such as certain background-colors or border-colors, will not take effect. Failure to comply with these guidelines could lead to your app being rejected or even a ban on your developer account by Google.
It's the responsibility of the merchant to ensure that their use of the Google Pay button follows Google's guidelines, and Ottu cannot be held responsible for any issues that arise from non-compliance. If you have any questions or concerns about using the Google Pay button, please consult the Google Pay guidelines or contact Google directly for assistance.
You can customize the Google Pay button using the Checkout SDK's formsOfPayment, googlePayInit and theme . The formsOfPayment property tells the Checkout SDK to render only the Google Pay button. If you don't include this property, the SDK will render all available payment options.
Properties like buttonColor, buttonType, buttonSizeMode and css properties like height, width, margin etc can be customized using theme while buttonLocale can be customized using googlePayInit .
If you have completed the stc pay integration between Ottu and stc pay, the Checkout SDK will handle the necessary checks to display the stc pay button seamlessly. When you initialize the Checkout SDK with your session_id and payment gateway codes pg_codes, the SDK will automatically verify the following conditions:
The session_id and pg_codes provided during SDK initialization must be associated with the stc pay Payment Service. This ensures that the stc pay option is available for the customer to choose as a payment method.
The Web SDK displays the stc pay button irrespective of whether the customer has provided a mobile number while creating the transaction or not.
You can customize the stc pay button using the Checkout SDK's formsOfPayment and theme properties. The formsOfPayment property tells the Checkout SDK to render only the stc pay button. If you don't include this property, the SDK will render all available payment options.
If you have completed the urpay integration between Ottu and urpay, the Checkout SDK will handle the necessary checks to display the urpay button seamlessly. When you initialize the Checkout SDK with your session_id and payment gateway codes pg_codes, the SDK will automatically verify the following conditions:
The session_id and pg_codes provided during SDK initialization must be associated with the urpay Payment Service. This ensures that the urpay option is available for the customer to choose as a payment method.
The Web SDK displays the urpay button irrespective of whether the customer has provided a mobile number while creating the transaction or not.
You can customize the urpay button using the Checkout SDK's formsOfPayment and theme properties. The formsOfPayment property tells the Checkout SDK to render only the urpay button. If you don't include this property, the SDK will render all available payment options.
Due to compliance requirements, KNET requires a popup displaying the payment result after each failed payment. This is available only on the cancelCallback when there is a response from the payment gateway. As a side effect, the user can not try again the payment without clicking on Apple Pay again.
The use of the popup notification described above is specific to the KNET payment gateway. Other payment gateways might have different requirements or notification mechanisms, so be sure to follow the respective documentation for each payment gateway integration.
To properly handle the popup notification for KNET, you need to implement the provided code snippet into your payment processing flow. The code looks like this:
The above code performs the following checks and actions:
It first verifies if the cancel object contains information about the payment gateway (payment_gateway_info).
Next, it checks if the pg_name property in payment_gateway_info is equal to kpay, indicating that the payment gateway used is indeed KNET.
If the above conditions are met, it retrieves the payment gateway's response from the pg_response property or, if not available, uses a default "Payment was cancelled." error message.
Finally, it displays the error message in a popup using the window.Checkout.showPopup() function to notify the user about the failed payment.
The SDK supports the following payment forms: applePay, tokenPay, ottuPG, redirect, googlePay, and stcPay. Merchants can display specific methods according to their needs.
For example, if you want to only show the Apple Pay button, you can do so using
formsOfPayment = [applePay], and only the Apple Pay button will be displayed. The same applies for stcPay, googlePay, and other methods.
To migrate from an older version to the latest version, please refer to the Installation section of the Ottu SDK docs. There you can find the SDK script with the latest version.
The SDK offers various predefined themes that merchants can use to easily change the checkout page’s appearance. Themes such as dark theme, minimal theme, hide headers, and hide amount are available. Each theme is predefined by specific css classes with unique properties.
Yes, after familiarizing yourself with the supported css classes, you can use the theme object to customize the appearance of any component you want.
Example: If you want to change Pay Button color to blue, you can use below class in theme
Yes, there are some compatibility nuances to be aware of:
For the Apple Pay button, it is mainly displayed on Apple devices and the Safari browser. For Chrome, it will only be displayed on the latest iOS 16.
For and Google Pay, stc pay & other payments methods, always refer to their official documentation for the most recent information about compatibility issues.
You can tailor the payment request for both Apple Pay and Google Pay using their respective initialization methods. These methods allow you to set various properties like API version, supported cards, networks, countries, and merchant capabilities etc.You can check the list of properties supported by ApplePay & GooglePay.
The tooltip indicates certain prerequisites for Apple Pay are not met. Reasons could include a pending iOS update, cards not added to the Wallet, invalid merchant configurations, domain not verified by Apple, or the device being unsupported or old. Ensure all Apple Pay requirements are met for a smooth payment experience.
Merchants can utilize the beforePayment hook. This allows for specific actions or checks to be performed prior to payment/redirection. Once your actions or checks are complete, resolve the promise to proceed with the redirection/payment.
