Is there any documentation of how the integration API calls from DNA center work. I am not looking for documentation on how to make API calls against DNA Center but instead any information on how the Integration API's behave (or as it is shown under platform->Manage->Configurations->General Settings "Rest Endpoint for Publishing Event").
I've tried using the devnet sandbox and having it send to a trash rest endpoint, but no information is ever posted although the Runtime Dashboard shows the tasks as completing successfully.
