Need guidance on connecting my web app to the calling web app with its authentication passed to me

Questions
1

I’m constructing a .net mvc web app that will be called from another web app via a URL. The other app will have already authenticated via SAML to Okta. What is the best way to seamlessly “pass” that authenticated user context to my web app.
Thanks,
Leo
