# Process face vs second id

`POST /omni/process/face-vs-second-id`

Base URL: `https://demo-api.incodesmile.com` — Incode demo environment

**Note**: This endpoint should be called only after [selfie](#/Onboarding/addFaceByThirdParty) and
[front-second-id](#/Onboarding/addFrontSecondIdV2) both are over.

It is validating user's selfie against photo from ID (1:1 recognition). Also, this call validates if user already exists
in the system (1:N recognition).

It is highly recommended that before calling this process-face endpoint, one should first finish following endpoints:
[add-front-secondId](#/Onboarding/addFrontSecondIdV2), [add-back-secondId](#/Onboarding/addBackSecondIdV2) (not required in
case of passports), [process-secondId](#/Onboarding/processSecondId) and [add-selfie](#/Onboarding/addFaceByThirdParty) in order
to get complete result view based on id verification, face recognition and liveness.
