Which one of SAML/OIDC should I go for when I want to integrate okta to my portal (react + express). Here, express is used to route API calls only. I also want to give role-based access to my portal.
I want to know which one of SAML/OIDC I should be using for such an application. If SAML, is there any article explaining how I should go about adding that to my portal?
