Dear developers,
this week a bug was discovered that affected the /accounts and /transactions endpoints. The error returned was ACCESS_EXCEEDED and the error message was "The access on the account has been exceeding the consented multiplicity without PSU involvement per day or limit for accessing of historical transactions." Today a fix has been deployed and the functionality on the /accounts and /transactions endpoints is back to normal. We apologize for the inconvenience.
Best regards,
Your Commerzbank Support-Team
