Face Match (1:1)

Within FACIA, the Face Match service takes center stage as a dynamic endpoint, propelling transaction requests into the realm of facial matching algorithms. This innovative algorithm meticulously evaluates the likeness between a Selfie (Photo) and either a Document or another Selfie (Photo), adopting a seamless 1:1 matching approach.

Create Face Match Transaction

This endpoint initiates a transaction request for the face match algorithm, serving as a 1:1 service. The endpoint accepts three fields in the request payload, as mentioned in the request parameters.

Endpoint

POSThttps://app.facia.ai/backend/api/transaction/create-transaction/face-match

Authorization:

Token Type: Bearer
Description:

This API utilizes Access token or Client-Secret key in header for authentication.

You can use your client_id and client_secret key when using the "/get-access-token" endpoint to obtain a Bearer token for authorization while connecting to this API. For additional details on Authorization, click Here

Request Parameter

Parameters	Description
type	Required: Yes Type: string Example: type=photo_id_match The type must be "photo_id_match".
face_frame	Required: Yes Type: file Example: face_frame=file File must be of type .jpeg, .jpg or .png.
id_frame	Required: Yes Type: file Example: id_frame=file File must be of type .jpeg, .jpg or .png.
client_reference	Required: No Type: string Minimum: 5 characters Maximum: 255 characters Example: client_reference="QWERTY12345" Required if allow_override field set to 1.
allow_override	Required: No Type: boolean Default value: 0 Accepted values: 0,1 The client reference is mandatory if the value of the override key is set as 1. The override key allow the system to replace the latest previous image with the new one against the specified reference number of the client’s reference.
enroll_face	Required: No Type: boolean Example: enroll_face=true Default value: true If you do not want the system to enroll the face then set the value of the key as false.
