Research direction

Start with the linked CyberSource Card-Present and EMV authorization examples and API reference, then compare their required EMV and point-of-sale fields with the provided sandbox payloads. Reproduce both contact and contactless requests and determine which value causes INVALID_DATA; done means documenting a corrected request that receives a successful authorization response.

Description

Following the examples at here and here, I am unable get a successful response in the sandbox environment.

Card Present + EMV (Contact)

Request payload
{
  clientReferenceInformation: { code: 'TC50171_3' },
  processingInformation: { commerceIndicator: 'retail' },
  orderInformation: { amountDetails: { totalAmount: '1', currency: 'SGD' } },
  pointOfSaleInformation: {
    cardPresent: 'Y',
    entryMode: 'contact',

    trackData: '%B4111111111111111^SMITH/BETTY^23121200123456789012**XXX******?*',
    emv: {
      tags: '9F3303204000950500000000009F3704518823719F100706011103A000009F26081E1756ED0E2134E29F36020015820200009C01009F1A0208409A030006219F02060000000020005F2A0208409F0306000000000000',
      cardSequenceNumber: '001',
      fallback: 'true'
    }
  }
}
Response Body

  status: 'INVALID_REQUEST',
  reason: 'INVALID_DATA',
  message: 'Declined - One or more fields in the request contains invalid data'
}

Card Present + EMV (Contactless)

Request payload
{
  clientReferenceInformation: { code: 'TC50171_3' },
  processingInformation: { commerceIndicator: 'retail' },
  orderInformation: { amountDetails: { totalAmount: '1', currency: 'SGD' } },
  pointOfSaleInformation: {
    cardPresent: 'Y',
    entryMode: 'contactless',
    catLevel: 6,
    terminalCapability: 5,
    trackData: '%B4111111111111111^SMITH/BETTY^23121200123456789012**XXX******?*',
    emv: {
      tags: '9F3303204000950500000000009F3704518823719F100706011103A000009F26081E1756ED0E2134E29F36020015820200009C01009F1A0208409A030006219F02060000000020005F2A0208409F0306000000000000',
      cardSequenceNumber: '001',
      fallback: 'true'
    }
  }
}
Response Body
{
  submitTimeUtc: '2020-04-23T11:22:38Z',
  status: 'INVALID_REQUEST',
  reason: 'INVALID_DATA',
  message: 'Declined - One or more fields in the request contains invalid data'
}

I have a feeling that the EMV values are incorrect, but am unsure what is wrong as the response is pretty vague. Would appreciate if someone could correct my mistake.
