# Face Match API (💲) This API is used to verify a user who has already undergone KYC verification or Multiple KYC verification. It verifies the user's identity by comparing their face with the previously submitted documents, eliminating the need for the user to undergo KYC onboarding again. If the user is already verified, the API will prevent them from undergoing the verification process again. {% hint style="info" %} Method: POST Authorization: Bearer Token Parameter: selfie\_image (Image File) (\*Mandatory) {% endhint %} ## Face Match/ Login Stels 1.
