New and improved error messages

We have updated Momentum’s synchronous error codes and messages to be actionable and detailed, allowing you to easily self-serve any issues you encounter.

The structure of the errors has not changed, meaning there is no need to change how you currently handle Momentum errors.

{
  "error_code": "missing_first_name",
  "message": "First name is required. Accepted values are letters, spaces, hyphens, apostrophes, periods, and diacritics."
}
