I have a situation where a client wants us to post data from a dataset to their webhook but it needs custom headers so I can supply an API key. The JSON writeback connector doesn't have any custom header configuration options as part of the connector setup.
I also explored using the JSON No Code connector to post data, but that connector doesn't allow you to specify a dataset for the source dataset (at least from what I can tell). It would be useful to have added as a feature as well.
I think this would be a very easy win that helps folks from having to write code for simple webhook POST requests.
