Submit a JSON object with the campaign item URL in the request body.
Returns the newly created Campaign Item as a JSON object in the response body.
You can pass 1 field only in the request JSON Object:
url.
The new Item is created with a status of CRAWLING. This is a read-only state - no fields can be modified.
The Item should be polled repeatedly until its status changes.
Once the Item status changes to RUNNING (or NEED_TO_EDIT), it can be edited.
