/api/v1/subscribe

It allows an external application to subscribe to our service and listen for triggered events from it. Currently,
Workato is the only application using this endpoint.
Once called, this will create a Script and a Hook (CustomAction or EventHook) that will call the given webhook_url
every time the hook is triggered.
Expected payload:

{
"recipe_id": "an ID to identify the recipe that is calling this endpoint",
"webhook_url": "a URL to callback when the event triggers",
"model": "Vitruvi model that is triggering the event.
We expect the model name in lowercase and with underscores",
"hook": "The hook, either Event or CustomAction",
"event_type": "Type of the event, e.g., ADD, UPD, DEL",
"custom_action_name": "The name of the CustomAction"
}
