When you register a {% data variables.product.prodname_github_app %}, you can specify a callback URL. When you use the web application flow to generate a user access token in order to act on behalf of a user, users will be redirected to the callback URL after they authorize the {% data variables.product.prodname_github_app %}.

You can specify up to 10 callback URLs. If you specify multiple callback URLs, you can use the redirect_uri parameter when you prompt the user to authorize your {% data variables.product.prodname_github_app %}, to indicate which callback URL the user should be redirected to. If you do not specify redirect_uri, the first callback URL will be used. For more information about using the redirect_uri parameter, see "AUTOTITLE".

The callback URL is different from the setup URL. Users are redirected to the setup URL after they install a {% data variables.product.prodname_github_app %}. Users are redirected to the callback URL when they authorize a {% data variables.product.prodname_github_app %} via the web application flow. For more information, see "AUTOTITLE."

For more information about generating user access tokens, see "AUTOTITLE". For more information about registering a {% data variables.product.prodname_github_app %}, see "AUTOTITLE." For more information about modifying a {% data variables.product.prodname_github_app %} registration, see "AUTOTITLE."
