API Reference – Create access token

Important

For security, access tokens are valid for 1 hour only.
If your token expires, make another Create access token request.

2. Create workflow

Create a European Identity Verification workflow:

You specify the workflowName and provide your unique identifier for the client.
You receive a workflowId and a Fourthline clientId.

3. Create SDK session

Create the App Drop-in session:

You provide the workflowId.
You receive a validationCode to pass to the SDK in your backend.

API Reference – Create SDK session

Important

• SDK validation codes are single use and expire after 2 hours.
• If the client stops in the middle of the workflow, you need to create a new SDK session.
• When the client closes the app, the validationCode is invalidated and cleared from the cache.

Status: The case status changes to one of the following and we send the relevant webhook notification:

Status	Description	Action
`pending`	The data is valid.	Wait for the next status.
`invalid_data`	We found invalid or missing data.	Create a new workflow.

Status: The case status then changes to one of the following and we send a webhook notification:

Status	Description	Action
`inconsistent_data`	We found inconsistent data.	Create a new workflow.
`completed`	We have processed the case. For our recommendation to accept or reject the client, see the risk code.	Download the CDD Report.

Check case status

When you receive webhook notifications, we recommend also requesting the full case details:

You provide the verificationId (same value as the workflowId).
You receive all the data on the case.
