QueryString for Accessing FaceAuth

FaceAuth is a sub-project of ID check, and administrators can create as many projects as they want. For users to receive additional authentication through FaceAuth, administrators must use the Face Auth URL within the Add-on project.
To reference a submission_Id that has been approved through ID document or Knowledge-based where a selfie image exists, it must be added to the URL through QueryString, and for security purposes, it must always be used in an encrypted state.
Encryption must use the API key within the FaceAuth project and uses AES-256.
For detailed methods, please refer to Query String Encryption in the Data Encryption and Decryption page.
Face Auth URL
  https://form.argosidentity.com/face-auth?pid={faceAuth_projectId}
Face Auth QueryString basic: Only add the submission_Id to reference
  https://form.argosidentity.com/face-auth?pid={faceAuth_projectId}&encrypted={sid={submission_Id}}
Face Auth QueryString with all parameters: sid, authUserId, authCf1, authCf2, authCf3, token
  https://form.argosidentity.com/face-auth?pid={faceAuth_projectId}&encrypted={sid={submission_Id}&authUserId={user Id}&authCf1={additional_info}&...&token={any tokenId}}
When encrypted
  https://form.argosidentity.com/face-auth?pid={faceAuth_projectId}&encrypted={encrypted}

Definition of Request Parameters

​
pid
string
required
Unique number assigned to the project when creating a FaceAuth project (automatically attached to the URL)
​
sid
string
required
submission_Id approved through ID document or Knowledge-based (sid is used for distinction)
​
authUserId
string
User Id that the administrator will assign to the user (this could be the user Id in the administrator’s service or the same userId used in ID document or Knowledge-based)
​
authCf1
string
Additional information that the administrator will assign to the user (e.g., email address, etc.)
​
authCf2
string
Additional information that the administrator will assign to the user (same as authCf1)
​
authCf3
string
Additional information that the administrator will assign to the user (same as authCf1)
​
token
string
Token that the administrator will add to the URL for security purposes.
Note!: This token operates separately from the pre-registered token in private mode.
The token is designed to assign a unique URL to each user when they authenticate through FaceAuth.
To apply a token, you must enable the token expiration condition setting option in the FaceAuth project, and it works as follows:
  • Count-based expiration: When the token is used once, the Token ID is immediately expired.
  • Time-based expiration: When the time has elapsed from the point when the token was used once, the Token ID is expired.
This token operates separately from the main project’s private mode token or pre-registered token.
For example, you can specify an arbitrary tokenId set by the administrator in the token, and even if you reuse the token used in the main project, it works because it is viewed separately. For a guide on enabling the token expiration condition setting option in the FaceAuth project, please refer to Add-on - FACE AUTH in the Service Guide.
For approved cases where no selfie image exists, the portrait image from the ID document will be used instead.

API Key

The Add-on API key serves to verify and authenticate client and server requests and is different from the project’s API key. It verifies the requester’s authentication information, and Argos Identity provides the appropriate response according to the request.
