# 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)
## API Methods
| Method | Description |
|--------|-------------|
| `wf.ready(callback)` | Execute code after the Browser API loads |
| `wf.getUserTrackingChoice()` | Returns `"allow"`, `"deny"`, or `"none"` |
| `wf.allowUserTracking(options?)` | Opt user into tracking |
| `wf.denyUserTracking(options?)` | Opt user out of tracking |
| `wf.onVariationRecorded(callback)` | Register a callback for variation events |
| `wf.setAttributes(scope, attributes)` | Set custom visitor attributes |
## Important Notes
- The Browser API is only available on sites with Webflow Analyze or Optimize enabled
- Custom JavaScript attributes (`setAttributes`) are only available on Enterprise sites
- Always wrap all API calls inside `wf.ready()` to prevent calls before initialization
- Place scripts in `<head>` custom code for earliest possible execution
## Reference Documentation
Each reference file includes YAML frontmatter with `name`, `description`, and `tags` for searchability. Use the search script in `scripts/search_references.py` to find relevant references.
### Getting Started
- **[references/introduction.md](references/introduction.md)**: Overview, capabilities, placement options, getting started
- **[references/wf-ready.md](references/wf-ready.md)**: `wf.ready()` API reference
### Consent Management
- **[references/consent-management.md](references/consent-management.md)**: Consent APIs, CMP integrations (OneTrust, TrustArc), custom consent solutions
### Optimize
- **[references/optimize-overview.md](references/optimize-overview.md)**: Optimize overview and quickstart
- **[references/variations.md](references/variations.md)**: Variations concept and `onVariationRecorded()` API reference
- **[references/attributes.md](references/attributes.md)**: Custom attributes and `setAttributes()` API reference
### Searching References
```bash
# List all references with metadata
python scripts/search_references.py --list
# Search by tag (exact match)
python scripts/search_references.py --tag <tag>
# Search by keyword (across name, description, tags, and content)
python scripts/search_references.py --search <query>
```
## Scripts
- **`scripts/search_references.py`**: Search reference files by tag, keyword, or list all with metadata
