We are facing a strange issue with API token, Created a token for online payment and able to do payment with that. The strange thing is, After every payment, the private token getting changed automatically.
We tried 4-5 payments on sandbox, It changing everytime and returns error below
"message": "400 Bad Request",
"message": "Keys for idempotent requests can only be used with the same parameters they were first used with.Try using a different key."
And it works only after changing the key.
Now, The question is, How to do multiple payments with this case.
