Get google oauth access token and implement google refresh token

Hey everyone! 👋 I'm working on implementing authentication in my Next.js app using BetterAuth with Google OAuth, and I could use some help with two things: How can I retrieve the user's access_token after login? What's the best way to implement token refresh with BetterAuth in a Next.js setup? If anyone has experience with this or can point me to some solid resources or examples, I’d really appreciate it! 🙏 Thanks in advance! 💙

You can query your DB

I could be wrong but I think we're in the makings for a better api regarding this. @bekacru ?

Is this the only way, if it is alright i can use somekind of caching to reduce db stress

Well currently for this i create a temporary way to refresh the oauth2 access token, let me know if you guys already implement the better way to do this thanks for the response

for the accessToken , it is stored on account Table along with refreshToken. you can use the internalAdapter for findAccount and get the access token for there . if you could get an access to ctx you can do this way

// this is by userID
 const result = await ctx.context.internalAdapter.findAccounts(userId)

// this is by accountID
 const result = await ctx.context.internalAdapter.findAccount(accountId)

// this is by userID
 const result = await ctx.context.internalAdapter.findAccounts(userId)

// this is by accountID
 const result = await ctx.context.internalAdapter.findAccount(accountId)

yeah for the refresh token , you can lets say i used twitter, i can do sth like this .. the url might not correct but you can pass your way of refreshing access token.

twitter: {
            clientId: process.env.TWITTER_CLIENT_ID || "",
            clientSecret: process.env.TWITTER_CLIENT_SECRET || "",
            async refreshAccessToken(refreshToken) {
                const response = await fetch("https://api.twitter.com/2/oauth2/token", {
                    method: "POST",
                    body: new URLSearchParams({
                        grant_type: "refresh_token",
                        refresh_token: refreshToken,
                    }),
                });
                const data = await response.json();
                return {
                    accessToken: data.access_token,
                    refreshToken: data.refresh_token,
                };
            },
        },

twitter: {
            clientId: process.env.TWITTER_CLIENT_ID || "",
            clientSecret: process.env.TWITTER_CLIENT_SECRET || "",
            async refreshAccessToken(refreshToken) {
                const response = await fetch("https://api.twitter.com/2/oauth2/token", {
                    method: "POST",
                    body: new URLSearchParams({
                        grant_type: "refresh_token",
                        refresh_token: refreshToken,
                    }),
                });
                const data = await response.json();
                return {
                    accessToken: data.access_token,
                    refreshToken: data.refresh_token,
                };
            },
        },
