Integrating on your Website

You will require to write some amount of code to collect the details from your customer and submit those details with PayU using a cURL with PayU Hosted Checkout integration.

This section provides some sample code blocks to submit the details you collected from your customer and they click Pay Now.

Note:

Javascript requires a crypto library to generate the hash. In this example, the crypto library that is built into Node.js is used, but if you’re running this code in a browser environment, you’ll need to use a different library.
