To start off the integration process, you would be provided with a test setup by PayU where you would be given a test merchant account and test credit card credentials to have a first-hand experience of the overall transaction flow. Here, you can make transaction request in our sample app (pointed to the testing server). Next step is to integrate the SDK code with your app. Once the testing is complete, you should be ready to point your app to the PayU production server for some real transactions.
You should start with test key and salt (which targets test server) to enable extra logs.
Please use the following test account (only on test environment):
This will succeed only on test environment. Also all other cards (real or not) will fail on test server.
