Using the pre-built UI

​

How it works

Your app redirects to a web page hosted by Authsignal (or displays it modally in an iframe). This is often the quickest way to integrate. You can configure your own custom domain and you can heavily customize the look and feel.

​

Integration steps

​

1. Backend - Track action

In your app’s backend, track an action which represents what your user is doing, e.g. signIn. You can do this using one of the Authsignal Server SDKs or you can call the Authsignal Server API directly using a RESTful HTTP request.

​

2. Frontend - Launch the pre-built UI

In your app’s frontend, pass the url from the track call to the Authsignal Web SDK to launch an enrollment or re-authentication flow.

authsignal.launch(url);

​

3. Backend - Validate challenge

Once the user has completed the challenge, Authsignal will send them back to the redirect URL you provided in step 1, appending a token as a query param which you can use to determine the result of the challenge server-side.
