We attempted to make a payment using Payco and then cancel it, but it appears that the transaction cannot be canceled. Although we receive a successful response when calling the /cancel API, the status is returned as "DONE," whereas it should be "REFUNDED."

Environment: DEV

Could you share the paymentKey of the transaction you tried to cancel? The full cancel API response body would also help.

Thanks for sharing the paymentKey. I checked the cancel logs and found the issue.

#

This is a server-side data sync issue, not a problem with your integration.
I'm escalating this to our internal team to investigate why the PAYCO cancellation detail wasn't written properly.
I'll get back to you once we have an update.

@stray herald
May I know what the issue was?
Also, will this issue be fixed in the development environment?
We need to run regular tests there.
