The Creative Submission API enables external buyers to submit their creatives for approval to publishers. This process allows buyers to bid on their creatives only after they have been approved.
The API provides endpoints for submitting creatives and checking their approval status.

In Hivestack, creative approval is handled at the file level. This means each file within a creative must be individually approved.
For instance, if a creative is initially submitted with a single image file, that image will be approved by the publisher. However, if additional files are added later through a bid response, those new files will require separate approval.
Approved files will remain available for playback, even if other files are pending approval. Additionally, creatives can support multiple formats, with each file needing individual approval.
