Offer a sponsored view. Protect the destination.

Understand LinkCode Sponsored Unlock sessions, explicit visitor choice, no-fill behavior, server verification and one-time redirect tokens.

The protected flow

✓The publisher explicitly enables Sponsored Unlock on one LinkCode.
✓The initial resolver returns safe gate copy and never includes the protected destination.
✓The visitor chooses Watch & unlock; LinkCode then selects an approved, eligible and funded direct campaign.
✓No-fill opens the normal destination through a short-lived one-time token.
✓A filled session counts only eligible active watch time received in ordered server events.
✓After verification, the server resolves the destination and issues a single-use redirect token.

Privacy and abuse protection

Rewarded sessions reuse LinkCode’s rotating privacy-preserving visitor and IP hashes, coarse location and bot/risk classification. They do not store a raw IP address.
