INVALID_USER_CREDENTIALS/JSON_EXCEPTION in “PayU” Android Integration

问题

I am tring to integrate payU payment gateway with my ecommerce application. I have a account on test payU with merchant id, key and salt.

I am working on this demo application, whenever i change parameters like merchant key, salt. I get a error code 5014.

Which can be either of them.

• int INVALID_USER_CREDENTIALS = 5014;
• int JSON_EXCEPTION = 5014;

Note: I am getting this as a response string:

"Something went wrong : Value <!DOCTYPE of type java.lang.String cannot be converted to JSONObject"

I am trying to debug it.But am unable to find a proper documentation.

Please help.

From the Payu Documentation,

This error occurs when merchant uses any of the following incorrectly.

• Wrong Key
• Wrong Salt
• Wrong Environment

Please note that ENVIRONMENT should be 1 for test credentials and 0 for live credentials

Solution: Please make sure the test key being used if you are hitting the test environment and vice-versa.
