Fetch Auth. Provider Callback URL in Flows

Question

I have successfully created Auth. Provider from my ScreenFlow.

I want to display the callback URL in the same flow.

Can someone please tell me whether there is any way to fetch the Callback URL of a specific Auth. provider in the flow?

I appreciate any help you can provide.

Answer 1

Thanks to the guideline by @identigral I have managed to obtain the callback URL by using the following approach - here Sample_Auth is the developer name for the Auth Provider

String ssoUrl = Auth.AuthConfiguration.getAuthProviderSsoUrl(null,null,'Sample_Auth');

String callbackUrl = ssoUrl.substringBefore('/auth');

callbackUrl += '/authcallback/Sample_Auth';

I found this can also be achieved with help of the URL class, which is much easier to work with.

String baseUrl = URL.getOrgDomainUrl().toExternalForm();

String callbackUrl = baseUrl+'/services/authcallback/Sample_Auth';
