 To send notification, you can use the HTTP request action, which sends an HTTP POST request to a specified URL with a JSON payload. The payload is defined using a payload template, which is a JSON-like syntax that allows you to include variables enclosed in double curly braces `{{variable}}`. This enables the
 dynamic injection of data into the payload when the webhook is triggered.

 The `resource` variable represents the triggering system resource. For example, when using the `ACTOR.RUN.SUCCEEDED` event, the resource is the Actor run. The variable will be replaced by the `Object` that you would receive as a response from the relevant API at the moment when the webhook is triggered. For the Actor run resource, it would be the response of the [Get Actor run](/api/v2#/reference/actors/run-object-deprecated/get-run) API endpoint.
 
 In addition to Actor runs, webhooks also support various events related to Actor builds. In such cases, the resource object will look like the response of the [Get Actor build](/api/v2#/reference/actor-builds/build-object/get-build) API endpoint.
