class InstallationStore

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)
