Import the contents of a CSV file into an existing HubDB table.
You can import the CSV into the draft version of the table (allowing a user to examine the table in HubSpot before making the updates live) by including
/draft at the end of the request path. See the examples for details.
This endpoint takes a multipart POST request. The first part will be a set of JSON formatted options for the import. The second part will be the CSV file you want to import.
