I verified my domain successfully via Apple Developer Account. But, when I try to call Apple's registerMerchant API they respond with:
statusMessage: Payment Services Exception Domain verification failed for merchantId... errorMessage=\"exception decoding Hex string: invalid characters encountered in Hex string\"" statusCode: 400
Did anyone encounter this error?
Apple was expecting to find a specific domain-verification-file (that they provided us). When I uploaded the correct file, the issue was resolved.
