Create a list

Creates an empty list with source API and status mapped, immediately ready to receive contacts through POST /lists/list/{listId}/contacts or the batch route. List names do not need to be unique: calling this twice creates two lists, so store the returned listId.

To make the contacts of the list enter a campaign, attach the list to the campaign (in the app or through the Campaigns API). Contacts added afterwards flow into the campaigns that use the list.

Do not send source: the value Manual is reserved to the web app and starts the list with most columns hidden, which removes their fields from GET /lists/list/{listId}/rows until contacts fill them.
