OpenID Connect (OIDC) is a modern authentication protocol built on OAuth 2.0. This guide walks you through configuring OIDC SSO for your Opik organization.

<Note>
OIDC SSO is available on Enterprise plans. This feature is not available in open-source deployments. [Reach out](https://www.comet.com/site/about-us/contact-us/) if you want to enable this feature for your Opik deployment.
</Note>

## Prerequisites

Before you begin, ensure you have:

- **Organization admin access** to Opik
- **Admin access** to your identity provider that supports OIDC
- **Enterprise plan** enabled for your organization
- **Email domain** you want to use for SSO (e.g., `company.com`)

## OIDC vs. SAML

OIDC offers several advantages over SAML:

| Feature | OIDC | SAML |
| --- | --- | --- |
| Protocol | REST/JSON-based | XML-based |
| Token format | JWT | XML assertions |
| Setup complexity | Simpler | More complex |
| Mobile/API friendly | Yes | Limited |
| Workspace sync | Via default workspace | Via attribute mapping |

Choose OIDC when:

- Your IdP supports OIDC (most modern IdPs do)
- You prefer simpler configuration
- You don't need attribute-based workspace sync

Choose [SAML](/v1/administration/authentication/saml) when:

- You need automatic workspace assignment based on user attributes
- Your organization requires SAML specifically

## Configuration overview

Setting up OIDC SSO involves:

1. **Register Opik** in your identity provider as an OIDC application.
2. **Configure Opik** with your IdP's OIDC endpoints and credentials.

## Step 1: Register Opik in your IdP

Create a new OIDC/OAuth application in your identity provider:

### Application settings

| Setting | Value |
| --- | --- |
| **Application type** | Web application |
| **Grant type** | Authorization Code |
| **Redirect/Callback URL** | `https://www.comet.com/opik/oauth/callback/<organization-id>` |

<Tip>
The exact callback URL will be displayed in your Opik SSO configuration page. Copy it directly from there.
</Tip>

### Required scopes

Ensure your OIDC application requests these scopes:

- `openid` - Required for OIDC
- `profile` - User profile information
- `email` - User's email address

## Step 2: Gather IdP information

After registering the application, collect the following from your IdP:

| Information | Description | Where to find |
| --- | --- | --- |
| **Client ID** | Unique identifier for your application | IdP application settings |
| **Client Secret** | Secret key for authentication | IdP application settings |
| **Authorization URL** | Endpoint for authorization requests | IdP documentation or well-known endpoint |
| **Token URL** | Endpoint to exchange codes for tokens | IdP documentation or well-known endpoint |
| **User Info URL** | Endpoint to fetch user profile | IdP documentation or well-known endpoint |

<Tip>
**Well-known endpoint**: Most OIDC providers expose a discovery document at `/.well-known/openid-configuration` containing all endpoint URLs.
</Tip>

## Step 3: Configure Opik

1. Navigate to **Admin Dashboard** > **SSO Configuration**.
2. Select **OIDC** as the SSO protocol.
3. Enter the following settings:

### Required OIDC settings

| Field | Description | Example |
| --- | --- | --- |
| **Domain** | Email domain for SSO users | `company.com` |
| **Client ID** | Application identifier from your IdP | `abc123xyz` |
| **Client Secret** | Secret key from your IdP | `secret_...` |
| **Authorization URL** | IdP's authorization endpoint | `https://idp.company.com/oauth/authorize` |
| **Token URL** | IdP's token endpoint | `https://idp.company.com/oauth/token` |
| **Callback URL** | Opik's callback URL | `https://www.comet.com/opik/oauth/callback/...` |
| **User Info URL** | IdP's user info endpoint | `https://idp.company.com/oauth/userinfo` |

### Optional OIDC settings

| Field | Description | Default |
| --- | --- | --- |
| **Default Workspace** | Workspace for new SSO users | Organization default |
| **Application Resource ID** | Custom resource identifier | Not set |

## Field reference

### Client ID

The unique identifier assigned to Opik when you registered it with your IdP:

- Created when you register the application
- Used in authorization requests to identify Opik
- Should be treated as public (not secret)

### Client Secret

The secret key used to authenticate Opik with your IdP:

- Created when you register the application
- Used when exchanging authorization codes for tokens
- **Must be kept secret** - never expose in client-side code

<Warning>
**Security**: The client secret is sensitive. If compromised, regenerate it in your IdP and update the configuration in Opik.
</Warning>

### Authorization URL (Auth Base URL)

The endpoint where users are redirected to authenticate:

```
https://idp.company.com/oauth/authorize
```

This URL receives authorization requests with:

- `client_id` - Your application's client ID
- `redirect_uri` - The callback URL
- `scope` - Requested permissions
- `response_type` - Always `code` for authorization code flow
- `state` - Security parameter to prevent CSRF

### Token URL (Access Token URL)

The endpoint where Opik exchanges authorization codes for access tokens:

```
https://idp.company.com/oauth/token
```

Opik sends a POST request with:

- `grant_type` - Always `authorization_code`
- `code` - The authorization code received
- `redirect_uri` - The callback URL
- `client_id` and `client_secret` - For authentication

### Callback URL

The URL where your IdP redirects users after authentication:

```
https://www.comet.com/opik/oauth/callback/<organization-id>
```

- Must be registered in your IdP's allowed redirect URIs
- Must match exactly (including trailing slashes)
- Opik generates this URL based on your organization ID

### Protected Resource URL (User Info URL)

The endpoint where Opik fetches user profile information:

```
https://idp.company.com/oauth/userinfo
```

Opik uses the access token to request:

- `sub` - User's unique identifier
- `email` - User's email address
- `name` - User's display name

### Default Workspace

When users authenticate via OIDC for the first time:

- They are added to the **default workspace** specified in SSO settings.
- If not specified, they are added to the organization's default workspace.
- Workspace assignment can be managed manually after initial login.

<Note>
Unlike SAML with workspace sync, OIDC does not support automatic workspace assignment based on user attributes. Users are added to the default workspace on first login.
</Note>

## Testing the configuration

After configuring both Opik and your IdP:

1. **Open an incognito/private browser window** (to avoid cached sessions).
2. Navigate to Opik's login page.
3. Enter an email address with your configured domain.
4. You should be redirected to your IdP for authentication.
5. After authenticating, you should be redirected back to Opik and logged in.

## Troubleshooting

### Common issues

| Issue | Possible cause | Solution |
| --- | --- | --- |
| "Invalid redirect URI" | Callback URL mismatch | Verify callback URL matches exactly in both Opik and IdP |
| "Invalid client" | Wrong client ID | Verify client ID is copied correctly |
| "Invalid client credentials" | Wrong client secret | Verify client secret, regenerate if needed |
| "Scope not allowed" | IdP scope restrictions | Ensure `openid`, `profile`, `email` scopes are allowed |
| User not created | Missing email claim | Verify IdP returns email in user info response |

### Troubleshooting checklist

1. **Verify client credentials**: Double-check client ID and secret.
2. **Check callback URL**: Must match exactly (including protocol, trailing slashes).
3. **Validate endpoint URLs**: Ensure all URLs are correct and accessible.
4. **Review IdP logs**: Check your identity provider's logs for errors.
5. **Test well-known endpoint**: Verify `/.well-known/openid-configuration` returns valid JSON.
6. **Check scopes**: Ensure required scopes are configured and allowed.

### Debugging with browser tools

Use browser developer tools to inspect the authentication flow:

1. Open **Network** tab before starting login.
2. Look for requests to your IdP's authorization endpoint.
3. Check for error parameters in the callback URL.
4. Review any error responses from the token endpoint.

## Security considerations

### Client secret protection

- Store the client secret securely in Opik's configuration.
- Never expose the client secret in logs or client-side code.
- Rotate the secret periodically per your security policies.

### Callback URL validation

- Only configure the exact callback URL provided by Opik.
- Do not add additional redirect URIs unless necessary.
- Review registered redirect URIs periodically.

### Token handling

Opik handles tokens securely:

- Access tokens are used server-side only.
- Tokens are not exposed to the browser.
- Sessions are managed securely after authentication.

## Next steps

- [Configure SAML](/v1/administration/authentication/saml) if you need workspace sync features.
- [Set up JWT authentication](/v1/administration/authentication/jwt) for programmatic access.
- [Manage users](/v1/administration/admin-dashboard/users) and workspace assignments.
