# WhatsApp

> Step-by-step screens for the WhatsApp channel: signing in on a computer and on a phone, step-up, and the claims your app can get.

## General scheme

A sign-in starts in your app: it sends the browser to the sign-in page with a standard OpenID Connect redirect. The user
confirms in a channel, and the browser returns to your app with a code that your app exchanges for tokens.

![Signing in through Veriqa: your app sends the browser to the sign-in page by an OpenID Connect redirect, the person confirms in a channel, and Veriqa redirects back so your app can exchange the code for tokens.](https://mintcdn.com/veriqa/ccCax_wh-JmrZJTK/images/examples/en-flow-sign-in.webp?fit=max\&auto=format\&n=ccCax_wh-JmrZJTK\&q=85\&s=ded6eede4a7e26ade7410dd12eb871de)

An action confirmation starts on your server: it creates a transaction through the Veriqa API. The user confirms in a
channel, and your server reads the answer and performs the action. The browser is not redirected.
