This endpoint allows buyers from external DSPs to submit creatives for approval.
The creative submission process is designed to minimize response times and occurs in the background.
Buyers can specify the creative's files using either the media_files field or the adm field, which accepts VAST or raw HTML content.
Upon submission, a message is returned to indicate that the creative and its files are being processed.
The query string parameters publisher_id and deal_id are mutually exclusive, with publisher_id taking precedence over deal_id.
If publisher_id is provided, the creative will be sent to the specific publisher for approval.
If deal_id is provided, the creative will be sent to the owner of the deal for approval.
