Integration APIs

In Real time, you can run PayU’s APIs in API Playground.

PayU has made many web-services for you. Each web-service has a specific function and hence can be used to automate different features. The basic format and execution of all web- services remain the same. Each web-service is a server-to-server call from your server to PayU’s server.

Web services can be accessed by making a server to server call on the below mentioned PayU URLs:
URL to be used:
For Production Server:


(form=1 shall return output in array form)


(form=2 shall return output in json form)

For Test Server:
