Salesforce Community signs in external users of an Experience Cloud site — customers and partners rather than internal Salesforce users. Because each site has its own host, this connector takes a Domain URI.

## Copy the redirect URI

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

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

## Create the connected app

1. Create a connected app in the org that owns the Experience Cloud site, as in the [Salesforce connector steps](/docs/connectors/salesforce).
2. Set the **Callback URL** to the redirect URI from Authdog.
3. In **Digital Experiences > All Sites**, note the site's full URL including any path prefix.
4. Make sure the site is active and allows self-registration or has the users you intend to sign in.
5. Copy the **Consumer Key** and **Consumer Secret**.

## Configure Authdog

| Field | Value |
| --- | --- |
| **Client ID** | The **Consumer Key** of the connected app |
| **Client Secret** | The **Consumer Secret** of the connected app |
| **Domain URI** | Your Experience Cloud site URL, e.g. `https://acme.my.site.com/customers` |

Save, then toggle the connection **active**.

## What Salesforce Community returns

Authdog requests the `openid email profile` scopes and reads the profile from ``<domain>/services/oauth2/userinfo``.

The site's own userinfo endpoint returns the community user's id, username, email, and display name — scoped to that site, not to the internal org directory.

Include the site's path prefix in the Domain URI. A site published at `/customers` will not authorize requests sent to the bare domain.

## 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 Salesforce Community button and complete the flow.
3. Confirm the user appears under **Users** in the console with a Salesforce Community identity linked.

## Troubleshooting

| Symptom | Cause |
| --- | --- |
| `invalid_client_id` | The connected app belongs to a different org than the site |
| Endless redirect to the site login page | The site is inactive, or the user is not a member of it |
| 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 |
