WhatsApp

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.

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.
