            bearerToken = ctx.response.headers.get("set-auth-token");
            localStorage.setItem("bearer_token", bearerToken ?? "");
        },
    }
);

❌ Failed code

result is null

import { authClient } from "@lib/auth-client";

            const authToken = ctx.response.headers.get("set-auth-token") // get the token from the response headers
            // Store the token securely (e.g., in localStorage)
            if (authToken) {

I am also getting this issue.

Why would the response header not be included in the client wide fetchOptions onSuccess context?

@DanielBoxer commented on GitHub (Aug 2, 2025):

I’m running into this too with a cross-domain setup. Could the social redirect be clearing all headers?

Maybe a workaround is to pass the auth token in the redirect url, but I’m not sure how to implement that with better-auth hooks.

I created a custom plugin to enable Bearer token authentication with Social Auth

// server/plugins/socialBearer.ts
import { BetterAuthPlugin } from 'better-auth';

export const socialBearer = () => {
  return {
    id: 'social-bearer',
    onResponse: async (response) => {
      const authToken = response.headers.get('set-auth-token');
      if (authToken) {
        const location = response.headers.get('location');
        if (location) {
          response.headers.set(
            'location',
            `${location}?authToken=${authToken}`,
          );
        }
      }
    },
  } satisfies BetterAuthPlugin;
};

// server/auth.ts
export const auth = betterAuth({
  ...,
  plugins: [
    bearer(),
    socialBearer(),
  ],
});

// client/callback-page.tsx
const url = new URL(window.location.href);
const authToken = url.searchParams.get('authToken');
if (authToken) {
  localStorage.setItem('bearer_token', encodeURIComponent(authToken));
  url.searchParams.delete('authToken');
  window.history.replaceState({}, document.title, url);
}```

@subasshrestha Thanks, I have it working now with your plugin!

For anyone else trying to get this working, I also had to remove the cookie header in my server for it to use the bearer_token:

const headers = new Headers(c.req.raw.headers)
headers.delete('cookie')
const session = await getAuth(c.env).api.getSession({ headers })

Hey, was this merged on any published version? Using the latest beta, but it does not seem to fix this issue or have the newly introduced bearerClient from the mentioned PR yet
