The installation store interface for asyncio-based apps.

The minimum required methods are:

  • async_save(installation)
  • async_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.

  • async_delete_installation(enterprise_id, team_id, user_id)
  • async_delete_all(enterprise_id, team_id)

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

  • async_save(installation)
  • async_find_bot(enterprise_id, team_id, is_enterprise_install)
  • async_delete_bot(enterprise_id, team_id)
  • async_delete_all(enterprise_id, team_id)
