Request Service API error codes

  • บทความ

Microsoft Entra Verified ID includes the Request Service REST API that allows you to issue and verify a credential. This article specifies the error codes for the Request Service API.

Error object

During public preview, the Request Service API returned errors in the following format.

{
  "requestId": "4bb6726f77af7623ab52962323016442",
  "date": "Thu, 28 Apr 2022 14:30:54 GMT",
  "mscv": "17ppwf3uxR10MfRR.1",
  "error": {
    "code": "client_request.invalid_include_qr_code",
    "message": "The request contains `includeQRCode`, but it is not boolean."
  }
}

This format is now changed into the following to enable both simpler error handling and better support for troubleshooting. In the new format, the outer error code and message fields have standardized values while the innererror object provide details on what caused the error.
