Is this suited for github?

  • Yes, this is suited for github

To Reproduce

  1. set google redirectURI to https://a.com/auth/callback (without provider)
  2. google redirects back to that url
  3. but better-auth not handle the url , return 404

Current vs. Expected behavior

expeected better-auth to recognize the url without provider in the url itself

in https://www.better-auth.com/docs/concepts/oauth#redirecturi it also mentione we can do it without provider


export const auth = betterAuth({
  // Other configurations...
  socialProviders: {
    google: {
      clientId: "YOUR_GOOGLE_CLIENT_ID",
      clientSecret: "YOUR_GOOGLE_CLIENT_SECRET",
      redirectURI: "https://your-app.com/auth/callback",
    },
  },
});

Hi @zhihengGet! I'm Dosu and I’m helping the better-auth team.

This is expected behavior - Better Auth requires the provider name in the callback URL path. The callback route is registered with the pattern /callback/:id, where :id is used to identify which OAuth provider should handle the callback. Without it, Better Auth returns 404 because it can't determine which provider to use.

The redirectURI configuration tells the OAuth provider where to redirect, but doesn't change Better Auth's internal routing - it still expects requests to hit /callback/google.

Solution: Use the callback URL with the provider name:

redirectURI: "https://a.com/api/auth/callback/google"

Or let Better Auth construct it automatically by setting your baseURL:

baseURL: "https://a.com/api/auth"
// Better Auth will automatically use: https://a.com/api/auth/callback/google

There's a related issue (#3877) where custom redirectURI settings are sometimes ignored. The current architecture requires the provider name in the path for identification.

To reply, just mention @dosu.

@Bekacru commented on GitHub (Feb 18, 2026):

The Dosu bot above is correct.

Better Auth requires the provider name in the callback URL path (/callback/:id) to identify which OAuth provider should handle the callback. The redirectURI configuration tells the OAuth provider where to redirect, but doesn't change Better Auth's internal routing.

Solution: Use the callback URL with the provider name:

redirectURI: "https://a.com/api/auth/callback/google"

Or let Better Auth construct it automatically by setting your baseURL:

baseURL: "https://a.com/api/auth"
// Better Auth will automatically use: https://a.com/api/auth/callback/google

This is the expected behavior by design.
