Authorization code doesn’t exist or is invalid for the client
Hi, we're trying to auth to the Retail Client API without any success.
We request the temporary Token without any issues, but when we try to exchange it for the access token we keep getting this error: "Authorization code doesn’t exist or is invalid for the client ".
The request is made under 30 sec so the temporary token should still be valid at this point, as for the client id we use the same as for the authorize request so there should also be no problem.
The weird thing is that when we access the Client API Access manager in the Retail POS we can clearly see that access and refresh token were assigned to the client but the api response constantly return the same message.
Could someone help us with this issue?
