We have got the developer pay API working in Sandbox but so far using any card details seems to return an APPROVED result (even with an expiry date in the past).
I tried the card details from
https://docs.clover.com/clover-platform/docs/testing-us-payment-flows and again, they are all approved.
Am I doing something wrong?
Are there some different card details to force the different response/results?
Thanks
