Installation

To integrate the SDK into your project, install it via Composer:

Alternative Installation (Without Composer)

If your project prefers not to use Composer for dependency management, you can manually include the FIB Payment SDK by following these steps:

• Clone the Repository: Clone the FIB Payment SDK repository directly into your project directory or any preferred location:

• Include in Your Project: Copy or move the cloned fib-php-payment-sdk directory into your project structure. You can place it wherever it suits your project best.

• Autoloading (if applicable): If your project uses autoloading, ensure that the src directory of the SDK is included in your autoloader configuration. For example, if using PSR-4 autoloading, you might add the following to your composer.json or equivalent autoloading setup:

• Usage: After including the SDK in your project, you can use its classes and functionalities directly in your PHP files.

Notes

• Ensure that the SDK repository URL (https://github.com/First-Iraqi-Bank/fib-php-payment-sdk.git) is correct and accessible.
• Manually managing dependencies may require additional effort to keep the SDK updated with the latest changes and fixes.
• Consider using Composer for managing dependencies whenever possible, as it simplifies dependency management and ensures compatibility with other packages.

Configuration

To configure the SDK, you need to set the following environment variables:

• FIB_API_KEY: Your FIB payment API key.
• FIB_API_SECRET: Your FIB payment API secret.
• FIB_BASE_URL: The base URL for the FIB payment API (default: https://api.fibpayment.com).
• FIB_GRANT_TYPE: The grant type for authentication with the FIB payment API (default: client_credentials).
• FIB_REFUNDABLE_FOR: The period for which transactions can be refunded (default: P7D, which stands for 7 days).
• FIB_CURRENCY: The currency used for transactions with the FIB payment system (default: IQD).
• FIB_CALLBACK_URL: The callback URL for handling payment notifications from the FIB payment system.
• FIB_ACCOUNT: The FIB payment account identifier.

Make sure to set these environment variables appropriately in your application's environment configuration.

Usage of the SDK

Below is a basic example of how to use the SDK:

Ensure Dependencies are Installed:

Make sure you have installed all required dependencies using Composer:

Set Up Environment Variables:

Create a .env file in the root directory of your project and configure the necessary environment variables. Refer to the .env.example file for the required variables.

Create a Payment Example Usage

• To create a payment, use the createPayment method. This method will return the payment details which you can store in a database or cache for later use in other functionalities like callback URL handling, checking payment status, cancelling payment, and refunding payment.

• Storing Payment Details: Once you receive the payment details from the createPayment method, you can store them in a database or a cache. This allows you to retrieve and use these details for further actions such as checking the payment status, processing refunds, or handling payment callbacks.

  • Database: Save the payment details in a relational database (e.g., MySQL, PostgreSQL) or a NoSQL database (e.g., MongoDB).
  • Cache: Use an in-memory cache (e.g., Redis, Memcached) to store the payment details for quick access.

• Returning Payment Details After storing the payment details, return them to the end user. The returned details include:

  • fib_payment_id: The unique identifier for the payment.
  • readable_code: A readable code for the payment.
  • personal_app_link: A link for the end user to proceed with the payment in the personal app.
  • valid_until: The expiration time for the payment.

By following these steps, you ensure that the payment details are securely stored and easily accessible for further processing.

Checking the Payment Status

To check the status of a payment, use the checkPaymentStatus method. This method requires the paymentId which was returned when the payment was created.

Refunding a Payment

To refund a payment, use the refund method. This method also requires the paymentId.

Cancelling a Payment

To cancel a payment, use the cancel method. This method requires the paymentId.

Handling Payment Callbacks

To handle payment callbacks, ensure your application has a POST API or URL that FIB can call to notify your application about payment status updates.

Callback URL Requirements Your callback URL should be able to handle POST requests with a request body containing two properties:

id: This represents the payment ID associated with the callback. Status: This indicates the current status of the payment. Refer to the "Check Payment Status" section of this documentation for more details. The status returned should mirror the data structure returned by the check status endpoint.

Notes

• /callback with your actual endpoint URL.
• Ensure your callback endpoint is accessible to FIB and handles errors gracefully.
• Implement the handleCallback method in your FIBPaymentIntegrationService class to handle the payment status update internally.
