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](https://console.authdog.com), select the project and environment, open **Authentication > Providers**, find **Vercel**, and click **Enable**. Copy the redirect URI shown in the form:

```url
https://identity.authdog.com/api/v1/callback/<connectionId>
```

## Create the application

1. Open the [Vercel integrations console](https://vercel.com/dashboard/integrations/console) and create an integration.
2. Fill in the name, description, and logo.
3. Under **Redirect URL**, paste the redirect URI from Authdog.
4. 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

1. Open your environment's hosted sign-in page, or link to `https://identity.authdog.com/api/v1/signin/<connectionId>`.
2. Select the Vercel button and complete the flow.
3. 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 |
