Pesapal API Integration Package for Laravel

A Laravel package that simplifies integration with the Pesapal payment gateway. This package allows developers to easily handle Pesapal's functionalities such as IPN (Instant Payment Notifications) registration, processing payments, and managing callbacks. Designed to work seamlessly with Laravel projects, including those using Livewire.

Features

• Secure handling of Pesapal API keys.
• IPN registration and callback URL configuration.
• Support for dynamic configuration per client.
• Laravel's route helper support for cleaner implementation.
• Easy-to-use methods for payment processing.
• Fully compatible with Livewire applications.

Installation

Install the package via Composer:

Publish the configuration file (Optional):

The configuration file config/pesapal.php will be created. Update it with your Pesapal credentials (Already done for you).

Configuration

Add the following variables to your .env file:

Update the config/pesapal.php file if you need to customize default settings.

Usage

1. Registering an IPN

IPN stands for Instant Payment Notification. When a payment is made against a transaction, Pesapal will trigger an IPN call to the notification URL related to this transaction. This notification URL is usually located on your servers. These notifications allows you to be alerted in real time whenever there is a status change for any transaction.

Use the Pesapal class to register an IPN:

Depending on the IPN URL that you set up in your .env file, the URL will be registered accordingly.

2. Get Registered IPNs

This endpoint allows you to fetch all registered IPN URLs for a particular Pesapal merchant account.

3. Making a Payment (Submit Order Request)

To initiate a payment:

Please Note that the $notification_id represents an IPN URL which Pesapal will send notifications to after payments have been processed.

You are required to register all IPN URLs after which a corresponding notification_id will be generated. Please refer to the IPN URL registration endpoint in the Pesapal API 3.0 documentation.

4. Handling Callbacks

Define callback routes in your routes/api.php:

Create the PaymentController controller as defined in the routes:

In your controller create the function handleCallback():

5. Get Transaction Status

Once Pesapal redirect your customer to your callback URL and triggers your IPN URL, you need to check the status of the payment using the OrderTrackingId.

This tracking ID is a unique order ID taht is generated by Pesapal from the data received in the initial response of the Submitted Order Request when making the payment.

Here is a Sample of the Response:

From that point it would have been best to store this data into the database so that you may query to check the status of the transaction.

6. Recurring Payments

In the process of making a payment there are extra options that this package has allowed you to add. These are the account_number and subscription_details.

• account_number : Customer's identification number known to your system. This can be an invoice number or an account number.
• subscription_details: Customer Subscription Object You can pass subscription data to Pesapal allowing a user to setup recurring payment.

The following is a sample of a subscription_details object in PHP

frequency: The period billed to the account is set out in the user contract. For instance, if users subscribe to a monthly service. Accepted values include DAILY, WEEKLY, MONTHLY or YEARLY

7. Refund Request

The refund request function allows you to refund a charge that has previously been processed but not yet refunded. Funds will be refunded to the credit / debit card or mobile money wallet that was originally charged.

• $confirmation_code: This refers to payment confirmation code that was returned by the processor
• $amount: Amount to be refunded.
• $username: Identity of the user who has initiated the refund
• $remarks: A brief description on the reason for the refund

8. Order Cancellation

The Order Cancellation Function enables you to revoke a previously placed order request that remains incomplete on our end. This API facilitates the cancellation of orders that have encountered failures or are pending transactions.

$trackingId: This refers to the original Pesapal Order tracking ID that was returned after submitting your order request earlier during the initial submit order request api call. It is similar to the one used to get the transaction status.

Testing

You can test the package in multiple environments:

1. Base Laravel Application: Create a controller and use the Pesapal class directly to process payments and handle callbacks.
2. Livewire: Create a Livewire component, inject the Pesapal class, and bind payment functionality to Livewire actions.
3. Inertia: Use Inertia to create Vue or React components and interact with the Pesapal class via API routes or Laravel controllers.

Ensure you have a valid Pesapal account and sandbox credentials for testing.

Security

• Credentials are encrypted in the database using Laravel's Crypt facade.
• Ensure APP_KEY in your .env is set and secure.
