Callback
Callback delivery is an advanced server-side pattern. Use it only when you specifically need decision handoff back into your own callback endpoint rather than polling or standard browser-driven reads.
When it fits
When your infrastructure is already organized around callback-based ingestion and you want decisions to arrive at a controlled server boundary.
What it does not change
The canonical concepts stay the same: jobs, decisions, consent, and beacons remain part of the same API model.
Need rollout review?
Contact the team
Start in the dashboard, choose Script Tag or Server API, and use contact only when you need rollout review, enterprise coordination, or non-standard integration help. Billing beacon rules live in the API concepts guide.
