## Backend class

For Django, add this class path to `AUTHENTICATION_BACKENDS`. For other
integrations, use the same class path in the framework-specific backend
setting.

| Backend name   | Class path                               |
|----------------|------------------------------------------|
| `slack`        | `social_core.backends.slack.SlackOAuth2` |

Slack

- Register a new application at [Slack](https://api.slack.com/applications), set the callback URL to
  `http://example.com/complete/slack/` replacing `example.com` with your
  domain.
- Fill `Client ID` and `Client Secret` values in the settings:
  ```default
  SOCIAL_AUTH_SLACK_KEY = ''
  SOCIAL_AUTH_SLACK_SECRET = ''
  ```
- Also it’s possible to define extra permissions with:
  ```default
  SOCIAL_AUTH_SLACK_SCOPE = [...]
  ```

  See auth scopes at [Slack OAuth docs](https://api.slack.com/docs/oauth).
- Limiting by team is possible by:
  ```default
  SOCIAL_AUTH_SLACK_TEAM = ''
  ```
