How to pass additional values to signIn() callback while using oauth in Authjs ( beta v5 )

[inderjotx]

What is the improvement or update you wish to see?

Using Auth.js ( next-auth v5 beta)
I am using Google Ouath , and building a role based sign-up , user can either sign-up as user or organization . I want to pass a additional param to the signIn("google") funation specifiing the role of the user. This will help me to create respective entity in the signIn callback

Is there any context that might help us understand?

I wasn't able to find any piece of information on Auth.js docs.

Does the docs page already exist? Please link to it.

I don't think that you can pass custom arguments to the signIn function.

You can extend the user session by adding the role field and even adding it to the database
Then, you can update the user role in the session callback from the token object.

// ...
callbacks: {
   async session({token, session}) {
     if (token.role && session.user) {
         session.user.role = token.role
     }
   }
  // ...
}

@Jay-Karia I am adding that already . During the sign-up progress , I need to get that additional argument from the user to create a entity with specified role .

    callbacks: {
        async signIn({ profile, user, account, credentials, ...other }) {

            const email = profile?.email;
            const name = profile?.name;
            const image = profile?.picture
            const phoneNumber = profile?.phone_number;
            const address = profile?.address?.formatted + ", " + profile?.address?.locality + ", " + profile?.address?.region + ", " + profile?.address?.country;

            // i want to get this arguement from the user
            const is_institute = false  


            let response = await getUserFromEmail({ email: email ?? null });
            let userData;

            if (response) {
                userData = response;
            } else {
                userData = await createUser({
                    email: email ?? null,
                    name: name ?? null,
                    image: image ?? null,
                    phoneNumber: phoneNumber ?? null,
                    address: address ?? null,
                    is_institute: is_institute
                })
            }

            if (userData) {
                return true;
            }

            return false;

        },
        async jwt({ profile, token }) {

            const email = profile?.email;

            if (email) {
                const user = await getUserFromEmail({ email: email ?? null });


                if (user) {
                    token.id = user?.id;
                    token.name = user?.name;
                    token.email = user?.email;
                    token.is_institute = user?.is_institute;
                    token.image = user?.image;
                }



            }

            return token;



        },
        async session({ session, token }) {



            session.user.id = token?.id as string;
            session.user.name = token.name as string;
            session.user.email = token.email as string;
            session.user.is_institute = token.is_institute as boolean;
            session.user.image = token.image as string;
            return session;

        },


    }

Okay,
When the register form is submitted, we'll call a function (a server action if you are using Next js) named register, we'll have to pass the values from the form as the function parameter.

We will get the role from the form input.

// actions/register.ts

export const register = async (values: z.infer<typeof registerSchema>) => {

    // validate data
    // ...

    // hash password
    // ...

    await db.user.create({
        data: {
            name: validatedValues.name.toLowerCase(),
            email: validatedValues.email,
            password: hashedPassword,
            role: validatedValues.role // getting the role from form input
        }
    })

    // ...

    return { msg: "User successfully registered, verify your email", status: "success" }

}

This function will create a user in database with the role specified in the form.
