PayPage – PHP ready to use Payment Gateway Integrations

Introduction to PayPage

PayPage is a popular PHP-based payment gateway integration platform that enables you to seamlessly integrate various payment gateways into your website or application. With PayPage, you can easily connect your website to payment providers like PayPal, Stripe, Square, and many others, allowing your customers to pay for goods and services with ease. In this tutorial, we will provide a step-by-step guide on how to use PayPage to integrate a payment gateway into your PHP application.

Getting Started with PayPage

Before you start, make sure you have the following:

• A PHP application (e.g., WordPress, Laravel, CodeIgniter, etc.)
• A PayPage account (sign up for a free trial or subscription)
• A payment gateway account (e.g., PayPal, Stripe, Square, etc.)

Once you have these, follow these steps:

Step 1: Set up PayPage

1. Log in to your PayPage account and navigate to the "Settings" page.
2. Click on "Payment Gateways" and select the payment gateway you want to integrate (e.g., PayPal, Stripe, etc.).
3. Follow the on-screen instructions to set up your payment gateway account and retrieve the necessary API credentials.

Step 2: Download and Install PayPage SDK

1. Navigate to the PayPage SDK download page and select the PHP version that matches your application.
2. Download the SDK and extract it to a directory on your server (e.g., /path/to/paypage/sdk).
3. Open the paypage-sdk.php file in a text editor and copy the contents.

Step 3: Integrate PayPage into Your Application

1. Create a new PHP file (e.g., paypage-integration.php) and paste the PayPage SDK code into it.
2. Set the PAYPAGE_API_KEY and PAYPAGE_API_SECRET variables to your PayPage API credentials.
3. Define the payment gateway API credentials (e.g., PAYPAL_API_USERNAME, PAYPAL_API_PASSWORD, etc.).
4. Create a new payment form on your website, using the PayPage payment form template or your own custom form.

Step 4: Process Payments

1. Create a new PHP file (e.g., process-payment.php) to handle payment processing.
2. Include the PayPage SDK file and set the payment form data (e.g., amount, currency, payment_method).
3. Call the PayPage->charge() method to process the payment.
4. Check the payment status using the PayPage->getPaymentStatus() method.

Step 5: Handle Payment Status

1. Create a new PHP file (e.g., handle-payment-status.php) to handle payment status updates.
2. Include the PayPage SDK file and set the payment ID.
3. Call the PayPage->getPaymentStatus() method to retrieve the payment status.
4. Handle the payment status update accordingly (e.g., update your database, send a notification to the customer, etc.).

Conclusion

Congratulations! You have successfully integrated PayPage into your PHP application. With PayPage, you can now process payments seamlessly and securely. For more information on using PayPage, refer to the official documentation and FAQs on the PayPage website.

Example Code:

<?php

// Set API credentials

// Set payment gateway API credentials
$paypal_api_username = 'YOUR_PAYPAL_API_USERNAME';
$paypal_api_password = 'YOUR_PAYPAL_API_PASSWORD';

// Create PayPage instance
$paypage = new PayPage($paypage_api_key, $paypage_api_secret);

// Create payment form
$payment_form = array(
    'amount' => 10.00,
    'currency' => 'USD',
    'payment_method' => 'paypal'
);

// Process payment
$payment_id = $paypage->charge($payment_form);

// Check payment status
$payment_status = $paypage->getPaymentStatus($payment_id);

if ($payment_status == 'success') {
    // Payment was successful, update database, etc.
} elseif ($payment_status == 'failed') {
    // Payment failed, handle error, etc.
}

?>
