Getting this error when posting an authenticate request to Apple business chat authenticate endpoint. I've registered auth URLS on the business chat account so that is not an issue. Can there be other possible reasons for this?
400 Bad Request : auth data not found in business registration
Facing the same problem. Did anyone get any solution for this?
If you are testing through MSP's Business Id then it will not work. Try using the Business Id of the BCP account, where you have added this oAuth details.
