We provide you with the following handlers:

• Token expiration handler
• Verification completion handler
• Dismissal control handler

👍

Tip

Handlers are optional, but we encourage you to provide at least tokenExpirationHandler to make sure the access token is active.

Token expiration

Because of the limited lifespan of the access token, it is important that you are able to handle the situation where the token expires and needs to be refreshed.

As a solution to this, you set tokenExpirationHandler. The handler should make a call to your backend, obtain the newToken, and then pass it back to the SDK by running the onComplete closure.

sdk.tokenExpirationHandler { (onComplete) in
    get_token_from_your_backend { (newToken) in
        onComplete(newToken)
    }
}

📘

Note

onComplete must be executed even if you fail to provide a new token; just pass nil in this case.

Verification completion

You can use verificationHandler to be informed when the verification process has been concluded with a final decision.

The parameter isApproved lets you know if the applicant was approved or finally rejected. If you'd like to get notified about any other stages of the verification process, use onStatusDidChange described in Status updates notification.

sdk.verificationHandler { (isApproved) in
    print("verificationHandler: Applicant is " + (isApproved ? "approved" : "finally rejected"))
}

Dismissal control

You can take over the dismissal control by assigning dismissHandler. The handler takes the current sdk instance and the mainVC controller. It's up to you to dismiss the mainVC in the manner that you see fit.

sdk.dismissHandler { (sdk, mainVC) in
    mainVC.dismiss(animated: true, completion: nil)
}
