class FileInstallationStore (*, base_dir: str = '/Users/kazuhiro.sera/.bolt-app-installation', historical_data_enabled: bool = True, client_id: Optional[str] = None, logger: logging.Logger = <Logger slack_sdk.oauth.installation_store.file (WARNING)>)

The installation store interface.

The minimum required methods are:

  • save(installation)
  • find_installation(enterprise_id, team_id, user_id, is_enterprise_install)

If you would like to properly handle app uninstallations and token revocations, the following methods should be implemented.

  • delete_installation(enterprise_id, team_id, user_id)
  • delete_all(enterprise_id, team_id)

If your app needs only bot scope installations, the simpler way to implement would be:

  • save(installation)
  • find_bot(enterprise_id, team_id, is_enterprise_install)
  • delete_bot(enterprise_id, team_id)
  • delete_all(enterprise_id, team_id)
