how do i connect the method api method by which i log in and django authentication ?
I can check the request status and pass jisung as an object. but it does not have a primary key and therefore I cannot use it

Answer 1

If the "third-party service" is some kind of social network, then there should be a lot of documentation for it. The keyword is OAuth.
If the "third-party service" is under its own control, then again Oauth (it is necessary to cut on both services) or other methods. Keywords: SSO - Single Sign-On, CAS - Central Authentication Service.
