oauth2 how to get the grant code in order to request access_token ?

[quent]

Hello,

I'm trying to configure OAuth with Fusionauth with my application (api core).
(I configured Fusionauth with user, application and the oauth).

When i hit my api endpoint, i do get a redirection to the fusionauth login page with all parameters as described in the documentation.

My question is about the redirect_uri : I understood if the login succeeds, the redirect_uri will be called with code and userState parameter

https://www.piedpiper.com/login?code=+WYT3XemV4f81ghHi4V+RyNwvATDaD4FIj0BpfFC4Wzg=&userState=Authenticated

If i understand well, the redirect uri will be called automatically within the workflow ?
If yes, can this redirect_uri be an API endpoint, in order to receive the temporary code, and then send a request for the access_token ?
I tried it but get an error

Thank you
