Hi everyone,
Hope you are doing great. We have some news for you:
We added enhanced response codes to transaction and refund resources. This way developers have better control over their workflow.
For example you get a specific response code if a credit card limit has exceeded and you can offer your customers appropriate error messages.
The whole list of new codes can be found in our api documentation within the section response codes.
With best wishes from Munich,
Nina and the whole Paymill Team
