Paid Ads campaigns (the Video Ad and Static Ad campaign types) get creators making creative for ads you run from your own ad accounts: the deliverable is the file itself, not a post on the creator's account.
The flow:
Creators upload their video or image through the Artec app; it lands in your campaign's review section.
You approve, request a revision, or reject: same review flow as organic content.
Approved creative gets Push to Meta and Push to TikTok buttons that upload it straight into your connected ad account as an ad creative: no downloading and re-uploading.
Payment structures for this channel: flat, per post, or spend share: where the creator earns a percentage of what you actually spend running ads built on their content, computed nightly from your ad account's own data.
