Using Postman

[DNoel26]

I recently started learning NextAuth and I have three questions:

1. Why does the session token only show in the browser and not Postman when I use the default signin and return a static user object?

2. How do I setup Postman to work so that it doesn't skip the authorize function and callbacks?

3. Why are my req and res objects undefined?

next-auth.session-token (only shows on browser)
next-auth.csrf-token (shows up on both browser and Postman)
next-auth.callback-url (shows up on both browser and Postman)

import NextAuth from 'next-auth';
import Providers from 'next-auth/providers';

const options = {
    session: {
        jwt: true,
        maxAge: 60 * 60,
    },
    callbacks: {
        async signIn(user, account, profile, req, res) {
            console.log('SIGNIN: ', user, account, profile, req, res);
            return true;
        },
        async redirect(url, baseUrl, req, res) {
            console.log('REDIRECT: ', url, baseUrl, req, res);
            return baseUrl;
        },
        async session(session, user, req, res) {
            console.log('SESSION: ', session, user, req, res);
            return session;
        },

        async jwt(token, user, account, profile, isNewUser, req, res) {
            console.log('JWT: ', token, account, req, res);
            return token;
        },
    },
    providers: [
        Providers.Credentials({
            credentials: {
                email: { label: 'email', type: 'email', placeholder: 'jdoe@email.com' },
                password: { label: 'password', type: 'password' },
            },

            async authorize(credentials, req) {
                **ENTERS HERE AND THEN CALLBACKS WHEN I SIGNIN ON LOCALHOST:PORT/API/AUTH/SIGNIN USING CHROME**
                **HOWEVER, DOES NOT ENTER HERE OR CALLBACKS USING POSTMAN**

                console.log('IN NEXT AUTH!!!');
                console.log(credentials, req);

               **REQ SHOWS UP AS UNDEFINED, SAME FOR REQ AND RES IN CALLBACKS**

                return {user: 'User'}
            },
        }),
    ],
};

export default (req, res) => NextAuth(req, res, options)
