After a user scans a QR code they are redirected to a callback URL. Yoti will then append a token attribute to this URL, which is used by the Yoti SDK to retrieve the user's information.
The URL will look like this: https://yourcallbackurl?token=YotiToken
By default, if you don't add a callback URL when creating your application, the user will be taken to a simple thank you page. In this case no token will be passed on to you.
