I'm trying to use the REST Connector, and I'm having some trouble. There are no examples in the Gallery and it's the only connector that doesn't have a page in the docs: https://docs.skyvia.com/connectors/

I have a URL that I would like to POST data to, and I want to set that URL up as a Connection using the REST Connector

There's a URL field that's straightforward, but there's a required Metadata field on the Connection. What is that for? What do I need to put in there?

Are there examples anywhere of a scenario like this?
