Seems your model is to glue together microservices we control. Is it possible to ingest webhooks that we would direct your way, but where it's actually coming from a third party API? We don't control the payload or headers in that instance.

I know we could first send it to a function to add the extra stuff and then to you, but that seems redundant.
