The Face Comparison endpoint uses biometric analysis to compare two face images and returns a confidence score indicating whether they depict the same individual. Use this for identity verification during onboarding or transaction approval.

Endpoint

POST /api/onboarding/biometrics/face/comparison

Response

200 OK

Field	Type	Description
`data.status`	boolean	`true` if the faces match, `false` if they do not
`data.response_code`	string	`"00"` indicates a successful comparison
`data.message`	string	Human-readable match result
`data.confidence`	integer	Match confidence percentage (0–100)

{
  "status": "success",
  "data": {
    "status": true,
    "response_code": "00",
    "message": "Face Match",
    "confidence": 100
  },
  "message": "Face comparison completed successfully"
}

A data.status of false indicates the faces do not match. Use data.confidence to apply your own threshold for acceptance (e.g., require >= 80 for a positive match).

400 Bad Request

Returned when one or both image URLs are missing, inaccessible, or do not contain a detectable face.

{
  "status": "failed",
  "data": [],
  "message": "Could not process one or both images"
}
