Wrapper
The Wrapper section in the main sidebar is where you manage your header-bidding configuration, deploy changes, and run experiments.
What's under Wrapper
| Subsection | Purpose | Link |
|---|---|---|
| Configs | Global wrapper settings (auction timeout, refresh, global floor, floor provider, custom script/CSS) | Wrapper configuration |
| Releases | Deploy config changes to production | Releases |
| Experiments | A/B test configuration changes | Experiments |
The full name is Prebid Wrapper; the portal sidebar abbreviates it to Wrapper. Both refer to the same thing.
How changes flow
Most day-to-day changes are config-only — they propagate through the CDN in seconds. Library rebuilds only happen when code or Prebid modules change.
Key settings
Configs
| Setting | What it controls |
|---|---|
| Auction Timeout | How long the auction waits for bid responses |
| Refresh | Ad-refresh trigger, interval, and cap defaults |
| Global floor | Wrapper-wide Price Floor (plus per-device overrides) |
| Floor Provider | Optional external floor endpoint |
| Custom Script / CSS | Wrapper-scoped custom code |
Currency (set on your account), price granularity (a GAM price-bucket setting), and user sync (Setup → User Sync) are configured elsewhere — not in Wrapper Configs.
Releases
| Feature | What it does |
|---|---|
| + Release | Create a draft release from a source config (or experiment), ready to deploy — it references that source, it isn't a bundle of staged edits |
| Copy a release | Duplicate a previous release into a new draft — the basis for rolling back (copy a good release forward, then deploy); there's no one-click rollback |
| History | Review past releases |
Experiments
| Feature | What it does |
|---|---|
| A/B test | Compare two configurations |
| Traffic split | Control % of users in each variant |
| Analytics | Measure experiment performance |
Common tasks
| Task | How |
|---|---|
| Deploy changes | Wrapper → Releases → + Release |
| Roll back | Copy the last known-good release into a new draft and deploy the copy — see Rolling back |
| A/B test a change | Wrapper → Experiments → A/B Test |
| Update global settings | Wrapper → Configs |
AI Assistant for wrapper tasks
The AI Assistant can handle wrapper chores by request — drafting a release from your current config, walking you through a rollback (there's no one-click rollback), or setting up an experiment — proposing each change for your approval before it's applied. See the AI Assistant guide.
