Hi, I do have this scenario.
I’ve API Service 1, API Service 2 and one Single Page Application(SPA) developed in React.
When user logged in, the SPA is able to call API Service 1 and as well as API Service 2 using the token obtained from user login on behalf of user.
But how do API Service 1 can call API Service 2 vice versa on behalf of user.
I’m able to achieve machine to machine to communication with authentication but how a micro service can call other micro service on behalf a user.
