How to PayPal Integration in PHP (Step by Step 2024)

Before diving into the coding process, it’s crucial to grasp the fundamentals of PayPal integration. PayPal offers various APIs and SDKs tailored for different programming languages, including PHP. By utilizing these resources, developers can seamlessly embed PayPal’s payment functionality into their web applications.

PayPal Integration in PHP – Step-by-Step

Setting Up Your PayPal Developer Account

The initial step towards PayPal integration is creating a developer account on the PayPal Developer platform. This account provides access to essential tools and resources needed for integrating PayPal services into your PHP application.

• Navigate to the PayPal Developer website.
• Sign up or sign in for a developer account.
• Access your developer dashboard to generate API credentials.

How to generate API credentials

To enable communication between your PHP application and PayPal, you must generate API credentials, including the Client ID and Secret Key. Follow these steps to obtain your API credentials:

• Log in or sign up to your PayPal Developer account.

• Navigate to Get API Credentials

• Navigate to the “Apps & Credentials” section.

• Create a new app and select the appropriate environment (sandbox for testing or live for production).

• Retrieve your Client ID and Secret Key from the newly created app’s dashboard.

Integrating PayPal Button

Now that you have obtained your API credentials, it’s time to integrate the PayPal button into your PHP website. Follow these steps to embed the PayPal button seamlessly:

• Include the PayPal JavaScript SDK in your HTML file.

<script src="https://www.paypal.com/sdk/js?client-id=<CLIENT_ID>&merchant-id=<MERCHANT_ID>&currency=USD"></script>

• Create a container for the PayPal button within your HTML markup.

<div id="paypal-button-container"></div>

• Initialize the PayPal button using the Client ID obtained earlier and define the transaction details.

<script>
paypal.Buttons({
createOrder: (data, actions) => {
 return fetch("/api/orders", {
 method: "post",
 })
.then((response) => response.json())
.then((order) => order.id);
},
onApprove: (data, actions) => {
 return fetch(`/api/orders/${data.orderID}/capture`, {
 method: "post",
     })
.then((response) => response.json())
.then((orderData) => {
 console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));
 const transaction = orderData.purchase_units[0].payments.captures[0];
alert(`Transaction ${transaction.status}: ${transaction.id}\n\nSee console for all available details`);
  }); 
 }
 }).render('#paypal-button-container');
 </script>

Testing and Deployment

After integrating the PayPal button into your PHP application, it’s essential to thoroughly test the functionality in a sandbox environment provided by PayPal. Once satisfied with the integration and functionality, you can deploy your PHP application to a live environment, ensuring a seamless payment experience for your users.
