Step 1: Initiate payment request with PayU

The merchant initiates PayU with the required transaction mandatory or optional parameters. This needs to be a server-to-server cURL call request. URL, parameters, and descriptions. For more information Collect Payment API - Sever-to-Server. Collect the response in the Collect Payment API - Server-to-Server under API Reference. The response for the S2S payment request is not similar to Merchant Hosted or PayU Hosted Checkout. For description of response parameters, refer to Additional Info for Payment APIs.
