  }
}

Response Body

  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.

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.
