To integrate PayUMoney in an AngularJS application, you'll need to use PayUMoney's payment gateway API to initiate and process the payment. PayUMoney provides a simple process to integrate their payment gateway into your application. Here's a step-by-step guide to integrate PayUMoney in your AngularJS application:

  1. Sign Up and Get Credentials: To start, sign up for a merchant account on the PayUMoney website ( After signing up, you will receive the required credentials: Merchant ID, Merchant Key, and Salt.

  2. Set Up Server-Side Code: Since PayUMoney requires server-side code to generate a secure hash and handle the payment response, you'll need to set up a backend server for your AngularJS application. The server-side code can be implemented in any server-side technology of your choice, such as Node.js, PHP, or ASP.NET.

  3. Generate Secure Hash: In your server-side code, implement a method to generate a secure hash using the provided Merchant Key and Salt. The secure hash ensures the integrity of the payment data and helps prevent tampering.

  4. Create Payment Request: In your AngularJS application, when the user initiates the payment process, send a request to your server-side code to create a payment request. Include the required details, such as the amount to be paid, order details, customer details, and the generated secure hash.

  5. Redirect to PayUMoney: Once the payment request is created, your server-side code should redirect the user to the PayUMoney payment gateway with the required payment details and a callback URL to receive the payment response.

  6. Handle Payment Response: After the payment process is completed on the PayUMoney gateway, the user will be redirected back to the callback URL specified in the payment request. In your server-side code, implement a handler for the payment response, which will receive the transaction status and other details.

  7. Show Payment Status to User: Once you receive the payment response in your server-side code, you can send the status back to your AngularJS application. Implement a success or failure page to show the payment status to the user.

It's important to note that while the payment integration process mainly involves server-side code, the AngularJS application plays a role in triggering the payment request and handling the payment response once the user is redirected back from the PayUMoney gateway.

Keep in mind that this is a high-level overview of the integration process, and the implementation may vary depending on your specific use case and the server-side technology you are using. Make sure to refer to PayUMoney's documentation and guidelines for more detailed integration steps and best practices.
