Callbacks

Developers can optionally define callbacks for events happening related to installation of their app. When a lifecycle event is fired, a POST request is made to the appropriate URL registered for the event.

Five particulars events (Install, Uninstall, Enable, Disable, Upgrade) can be registered to a callback under the callback section in App Registration. Each URL must use HTTPS to ensure data is sent securely.

📘
Authentication
Apps can verify that the request came from Seismic using the x-seismic-signature request header, which is set with all life-cycle requests.

Validation

🚧
Signing secret
All apps using callbacks should generate a signing secret for their app.

Additional details on signing secrets can be found here .

❗️
Acknowledgement
If callbacks are utilized, a response is required within 3 seconds with a 202. Failure to respond for any reason will block the action/event from occurring.

The five events that are available include:

Event	Description
Install	Occurs when an app is installed from the app catalog by a Seismic adming.
Uninstall	Occurs when a Seismic admin removes an app from their tenant.
Enable	Occurs when a Seismic admin enables an app. Until an app is enabled its features will be inactive - API client Event subscription * Extensions
Disable	Occurs when a Seismic admin disables an app. Disabling an app will deactivate all app functionality for a given tenant.
Upgrade	Occurs when a Seismic admin upgrades an app.
