Does this help with Sign in with Vercel?

does this help me with implementing Sign in with Vercel?

Based on my research, I can now give you a comprehensive answer about whether the @vercel/sdk helps with implementing "Sign in with Vercel".

##Answer

Not directly. The @vercel/sdk is primarily a server-side SDK for the Vercel REST API - it's designed to manage Vercel resources (deployments, projects, domains, teams, etc.) programmatically using a bearer token. It's not specifically built for implementing "Sign in with Vercel" OAuth flows in your application.

###What "Sign in with Vercel" is:

"Sign in with Vercel" is an OAuth 2.0 + OpenID Connect (OIDC) based authentication feature that lets users log into your application using their Vercel account (similar to "Sign in with Google" or "Sign in with GitHub"). It's available via Vercel's Identity Provider (IdP).

###What the SDK does offer:

The SDK does have one relevant endpoint - exchangeSsoToken in the authentication module:

// From docs/sdks/authentication/README.md
await vercel.authentication.exchangeSsoToken({
  code: "<value>",
  clientId: "<id>",
  clientSecret: "<value>",
  grantType: "authorization_code",
});

This is specifically for Marketplace Integrations (not consumer apps) - it exchanges an OAuth authorization code for an OIDC token when building Vercel integrations.

###What you'll need to implement "Sign in with Vercel":

1. Create an app from the Vercel Dashboard
2. Get a Client ID and Client Secret
3. Implement the standard OAuth 2.0 flow yourself (or use a library like Better Auth, NextAuth/Auth.js, or Auth0):
   • Redirect users to https://api.vercel.com/oauth/authorize
   • Handle the callback with the authorization code
   • Exchange the code for tokens at https://api.vercel.com/oauth/access_token

###Recommendation:

Check out:

• Vercel's official documentation
• Vercel's reference app
• Libraries like Better Auth which have built-in Vercel provider support

The @vercel/sdk becomes useful after you've authenticated - once you have access tokens, you can use the SDK to interact with the Vercel API on behalf of the user.
