Veriff is a certified IDSP under the UK Digital Identity and Attributes Trust Framework (UK DIATF), UK Government site[↗]

Within the framework of UK DIATF, we offer the following solutions:

Contact your solutions engineer for info and configuration.

Prerequisites

  • You have a regular identity verification integration set up with Veriff

  • The check is configured for that integration by your Solutions Engineer

  • You have configured the decision webhook to get responses from Veriff (see the Webhooks section for info)

  • You are prepared to send the end-user to Veriff verification flow

Flow overview

UKDIATF Certified Identity Verification (M1A)

This is a solution that is completed using Veriff’s end-user flow (cannot be customized). Sending the address on session creation is optional.

Step 1: create a session using the POST /sessions endpoint

  • See the POST /sessions[↗] section for a detailed overview of how to create a session

  • Sending the verification.address.fullAddress parameter is optional

Step 2: create a session using the POST /sessions endpoint

  • Open the response payload of the POST /sessions[↗] request you just made

  • Use the URL in the verification.url parameter in the payload

  • A web flow will start, which will guide you through the process

Step 3: wait for session decision and decision webhook response

  • As soon as the session is verified, the decision webhook will send the response with session status. It will be one of 9000-code statuses

  • In case the session is declined, the webhook contains relevant info about the reason

    • The reason for decline is visible in:

      • verification.code ,

      • verification.reason and

      • verification.reasonCode parameters.

UKDIATF Certified Identity Verification (M1B)

This is a solution that requires that the end-user's address is provided to return info from registries, and that the flow must be completed using Veriff's verification flow (cannot be customized).

Step 1: create a session using the POST /sessions endpoint

  • See the POST /sessions[↗] section for a detailed overview of how to create a session

  • Sending the verification.address.fullAddress parameter is mandatory

Step 2: capture user pictures and videos via verification flow

  • Open the response payload of the POST /sessions[↗] request you just made

  • Use the URL in the verification.url parameter listed in the payload

  • A web flow will start, which will guide you through the process

Step 3: wait for session approval and decision webhook response

  • As soon as the session is approved, the decision webhook will send an approved response

  • This response will include the session status, as well as all the data that was extracted from the UK DIATF checks

    • This info is visible in verification.additionalVerifiedData.UKTFCheckResult array

  • In case the session is declined, the webhook contains relevant info about the reason

    • This info is visible in:

      • verification.code,

      • verification.reason,

      • verification.reasonCode and

      • verification.additionalVerifiedData.UKTFCheckResult parameters

UKDIATF Certified Identity Verification (L1B)

The solution is a UK-certified version of Veriff’s standard identity verification. You must use Veriff’s end-user flow to capture the document & selfie, but you can customize the flow.

If you are not integrated with us yet, see the Getting started section for first steps. If you are, contact your Solutions Engineer for info and configuration.

Find decision and/or session related info

M1A webhook response

M1A Webhook response = decision webhook response

M1B webhook response

M1B Webhook response = decision webhook response with specific properties in the verification.additionalVerifiedData.UKTFCheckResult array.

The relevant data is presented in strings, marking the result of its nominal check.

These checks are executed in succession and if the preceding check fails, the succeeding one is skipped.

The order of executing the checks is as shown below, but in the webhook payload the order may be random.

  • additionalVerifiedData.UKTFCheckResult.CIFAS

  • additionalVerifiedData.UKTFCheckResult.Electoral roll and Credit History UK

  • additionalVerifiedData.UKTFCheckResult.PEP

Approved session

Scenario: all the checks are successful.

The sample and explanation below contain only the UK DIATF-related part of the webhook.

The decision webhook is used for many purposes, to find more info about it, see the decision webhook documentarion.
