TruFace Validation

Product: Validators

You can use TruFace to help your company identify, block and report fraudsters faces. Here is how it works:

  • When making an onboarding process: Our system will automatically check if the person undergoing your onboarding process has been reported before and will alert you.
    • Report faces: If you identify fraudsters, you can report and block those faces and these will be added to your collection.
    • If you mistakenly blocked a face: Don’t worry! You also have the option to unblock it.
    • Checking Faces: The process involves checking against your registered collection of blocked faces.
      • Note: Optionally your company could make use of risky faces detected by Truora. This requires a request for access, to do so please Contact Us.

Prerequisites

Before you begin, make sure you have the following:

  1. Truora API-Key: This key grants access to our services. If you don’t have one already, set up an account and then go to Authentication to obtain your Truora API-key.

  2. Media Files: You will need a reference image to perform user enrollment (Report a face) and another image to compare and make the validation (Check a face).

  3. Postman: Use Postman or any other collaboration tool for API development. Although it is not required to perform the integration, it will help perform tests along the way.

Truora provides a Postman collection online that includes the necessary tools to simplify the testing process.

Blocking faces

  • Create an enrollment for the validation account.
  • Use fraud_reason to block a face from being validated.
  • Save the account_id and enrollment_id from the response, since these will help you identify people who have been reported.

1. Create enrollment (Report a Face)

Setup main Request Headers and Body

To configure the main request headers and body, follow these steps:

  1. Create a POST request to the endpoint https://api.validations.truora.com/v1/enrollments.

  2. Set the Headers

        "instructions": {
            "file_upload_link": "https://files.truora.com/xxxxxxxxxxx"
        }
    }

Note

  • The validation_id and file_upload_link returned by this endpoint will be used in subsequent steps.

2. Upload Picture

The reference image must be submitted through a PUT request to the URL returned in the file_upload_link field of the previous step, selecting the Binary type in the Body. The image formats supported are: jpeg, png and webp. Maximum size is 10 MB.

After sending the PUT request you will receive a response similar to the following:

PUT
{{file_upload_link}} 

    {
        "code": 10200,
        "http_code": 200,
        "message": "Successfully uploaded"
    }

3. Get Validation

The Get validation request allows you to retrieve the current status and results of a validation. The validation_status begins as pending. Upon completion, the validation can either be success or failure.

  • To obtain the validation results, send a GET request to the endpoint https://api.validations.truora.com/v1/validations/{{validation_id}}, where validation_id is the identifier returned in the Create validation (Check a Face) request.
  • If you want to obtain links of the reported face image and the photo uploaded by the user, send the query parameter show_details with value true in the Get validation request, and you will receive the response with the links validation_input_files and input_files.
    • NOTE: These links will be valid for 15 minutes. To generate new links, the Get Result endpoint must be called again to return the result of the process with new links.

Once executed you will receive a response similar to the following:

GET
/v1/validations/{{validation_id}} 

        {
            "validation_id": "VLD853e95094e1bb5c938xxxxxxxxxxx",
            "ip_address": "xxx.xxx.xx.xx",
            "account_id": "ACC54350f7b7983b3c0aee50xxxxxxxxxxx",
            "type": "face-search",
            "validation_status": "failure",
            "failure_status": "declined",
            "declined_reason": "fraudster_face_match_in_client_collection",
            "creation_date": "2021-08-03T03:03:34.849954642Z",
            "message": "matched with face reported in enrollment ENR019e4390008b25634d8xxxxxxxxxx for fraudster",
            "fraudster_enrollment_id": "ENR019e4390008b25634d8xxxxxxxxxx"
        }

Note:

  • If the validation_status is success, it indicates that the user’s face was not found in any collection of reported faces.
  • If the validation_status is failure and the declined_reason is fraudster_face_match_in_client_collection, it indicates that the user’s face matched one reported as a fraudster.

Unblocking a Face

Delete enrollment (Unblock a face)

In order to unblock faces from Truora’s services you must:

  • Know the enrollment_id returned in Create enrollment (Report a Face) step.
  • Create a DELETE request to the endpoint api.validations.truora.com/v1/enrollments/{{enrollment_id}}.

The following success message confirms that the face has been unblocked:

DELETE
/v1/enrollments/{{enrollment_id}} 

    {
        "message": "Enrollment was successfully deleted"
    }

Getting results automatically (Webhooks)

To get validation results automatically, you must subscribe webhooks. For more information, please see Webhooks section.

Note: The hook only contains the validation result information. If you want to obtain links of the reported face image and the photo uploaded by the user, you must:

  • Decode the hook response and extract the value of validation_id field.
  • Use the validation_id to make the Get validation request with the query parameter show_details set to true.
  • The Get validation response will include the links in the fields validation_input_files and input_files.
  • These links will be valid for 15 minutes. To generate new links, the Get validation endpoint must be called again to return the result of the process with new links.

Declined and Expired reasons

Whenever a validation fails due to inconsistencies in the validation process or expires in the validation process, the API provides a reason to indicate why the validation was declined or expired:

  • To learn more about the possible declined reasons, please visit the Declined Reasons section.
  • To learn more about the possible expired reason, please visit Expired Reasons section.

Additional configurations

Using our API you can configure other parameters to improve the behavior of the validators and the user experience according to your particular needs. Please see the Config Validator Guide for more information on customization.

Please Note:

  • The config parameters you will see in the Config Validator Guide are global parameters for your account and will affect all the validations across your account.
  • However, validations performed using the flow you created will prioritize the configuration in the Validator Block of your flow. All other parameters, not configurable within the Flow Builder, will take the global configuration values.
