Bad Request. When a payer-scoped Recipient's businessAddress is rejected, errors[0].field is
businessAddress and errors[0].details describes the reason. errors contains a single item; if
more than one address problem is found, they are combined in that one details string. Other rejected
requests return the generic Bad request details without field.
details is informational and may change; rely on errors[0].field to identify the field to fix. It
uses internal field names: addressLine1 = line1, stateOrProvince = state, zip = postalCode.
Address Line 1 (businessAddress.line1) rules include:
- At least 2 characters (any country).
- When
businessAddress.country is US, at least one letter (A-Z), e.g. 12345 and #100 are rejected.
