Vercel signs users in with their Vercel account, which suits deployment tooling and integrations that already read a team's projects.
Copy the redirect URI
In the Authdog console, select the project and environment, open Authentication > Providers, find Vercel, and click Enable. Copy the redirect URI shown in the form:
https://identity.authdog.com/api/v1/callback/<connectionId>Create the application
- Open the Vercel integrations console and create an integration.
- Fill in the name, description, and logo.
- Under Redirect URL, paste the redirect URI from Authdog.
- Save, then copy the Client ID and Client Secret.
Configure Authdog
| Field | Value |
|---|---|
| Client ID | The client identifier from the provider |
| Client Secret | The client secret from the provider |
Save, then toggle the connection active.
What Vercel returns
Authdog requests the openid profile email scopes and reads the profile from https://api.vercel.com/login/oauth/userinfo.
The userinfo endpoint returns the sub identifier, name, email, and avatar for the signed-in Vercel user.
A Vercel account can belong to several teams. Sign-in identifies the person, not the team — resolve team membership through Vercel's API after the session exists.
Test it
- Open your environment's hosted sign-in page, or link to
https://identity.authdog.com/api/v1/signin/<connectionId>. - Select the Vercel button and complete the flow.
- Confirm the user appears under Users in the console with a Vercel identity linked.
Troubleshooting
| Symptom | Cause |
|---|---|
invalid_redirect_uri |
The redirect URL on the integration does not match |
| Redirect or callback URL error | The URI registered with the provider does not match Authdog's exactly |
| Works in one environment only | Each environment has its own connectionId, and so its own redirect URI to register |
