Webflow Browser API

The Browser API is a JavaScript interface exposed via the global wf object on all Webflow sites with Analyze and Optimize enabled. It requires no manual installation. Use it to manage consent, track experiments, and personalize user experiences.

Key Concepts

• Global wf object — Automatically available on all sites with Analyze or Optimize enabled
• wf.ready() — All Browser API calls must be wrapped in this readiness callback. See references/wf-ready.md
• Consent management — Three methods to manage tracking consent: getUserTrackingChoice(), allowUserTracking(), denyUserTracking()
• Variations — Track experiment results via onVariationRecorded() and forward to analytics tools
• Custom attributes — Set visitor attributes via setAttributes() for audience targeting and result filtering (Enterprise only)
