Add functionality to REST API connector to handle POST requests

Micah Johnson

The current REST API connector (which is in preview) is only designed to handle GET requests, but adding POST functionality would greatly increase the connector's utility. The POST method allows for more complex API calls that use nested JSON, arrays, multiple criteria, pagination info, etc. A GET request can only pass query parameters in the URL, which quickly becomes messy or limited in length. Using POST avoids URL size limits and allows structured filtering. I believe that most of this could be accomplished through the upload of a JSON template with the POST call details.

Large, external datasets - such as government data - require the POST method and often require a script to call the metadata for page info and then cycle through multiple pages to bring in the full dataset. They also require date parameters and so on.

Thanks for consideration of the idea.
