All live-camera parameters go on: ``` https://app.posetracker.com/pose_tracker/tracking ``` This page lists only flags **the tracking page actually reads**. Overlay, silhouette, and timer colors exist **only on this URL**. The SDK uses component props and `options.features` instead — [Provider & client](/reference/provider-client) and the [param map](/reference/features-plans#webview-param--sdk-map). Upload uses a **different path** and extra flags: [Upload tracking](/webview/upload). ## Required | Param | Example | Role | | ------- | -------------- | ------------------------------------------------------------ | | `token` | `YOUR_API_KEY` | Dashboard API key (`api_uuid`). Always required on this URL. | ## What to track You may omit all three for **keypoints-only** (pose stream, no reps). If you set more than one, the page returns an error. | Param | Example | Role | | ----------------------------------- | --------- | ------------------------------------------------------------------------------------------- | | `exercise` | `push_up` | Catalog id — [Exercises](/reference/exercises) | | `userExercise` | UUID | Custom movement from PoseTracker Studio. **WebView only** — the SDK does not take this UUID | | `reference` or `reference_movement` | UUID | [Reference movement](/webview/reference-movement). **WebView only** | ## Streams and scoring (plan-gated) | Param | Default | Role | | ----------------- | --------------------------------------- | ---------------------------------------------------------------------------------------------------------------------- | | `skeleton` | `true` | `true` / `false`, or a skeleton `api_uuid` | | `keypoints` | `false` | Raw keypoints **during** an exercise (paid). Pose-only (no exercise) always streams | | `angles` | `false` | Joint-angle stream — paid | | `progression` | `false` | 0–100 within the current rep or hold — paid | | `recommendations` | `false` | Form cue strings — paid. **Not emitted for every exercise**; always use `counter.form_score` for the counted-rep grade | | `minGrade` | — | `A`…`D` — only count reps at or above this grade | | `userHeightCm` | — | **Required** for `jump_analysis` | | `devicePitchDeg` | — | Jump camera-tilt compensation | | `scoring_profile` | `kali-analysis` when `reference` is set | Reference mode: `default` \| `kali` \| `kali-analysis` | Plan matrix: [Features & plans](/reference/features-plans). ## Layout and boot | Param | Role | | ------------------------ | --------------------------------------- | | `width` / `height` | Pixel size of the camera surface | | `isAndroid` or `android` | `true` — Android WebView tweaks | | `loading_message` | Boot overlay copy | | `postureBox` | Legacy placement box (`true` / `false`) | ## Placement overlay and timer Hosted-page appearance. Ignored if you are not using this tracking URL. | Param | Example | Role | | --------------------------------------------------------------------------------------------------------- | ------------- | -------------------------------------------------- | | `placementOverlay` | `true` | Gray padding + start-pose silhouette | | `placementZoneColor` | `#19221f` | Fill outside the safe zone | | `placementOverlayOpacity` | `0.45` | Zone opacity `0`–`1` | | `placementImageOpacity` | `0.9` | Custom placement image opacity `0`–`1` | | `placementBoxStrokeColor` | `#e2e2ef` | Safe-zone border | | `silhouetteColor` / `silhouetteShadow` | hex | Silhouette stroke / halo | | `silhouette` | `false` | Hide the mannequin | | `placementZone` | `false` | Hide the gray padding | | `timer` | `3` or `true` | Post-placement countdown (`true` → 3 s) | | `timerSeconds` | `5` | Override when `timer=true` | | `timerBg` / `timerColor` / `timerBorder` | hex | Timer card | | `guide` | `true` | Orbit rings (e.g. `shoulder_roll`). Off by default | | `engineDebug` | `true` | Internal HUD — **do not ship** | | `placementOverlayImageUrl` | URL | Custom placement art | | `paddingHorizontal` / `paddingVertical` / `paddingLeft` / `paddingRight` / `paddingTop` / `paddingBottom` | number | Placement insets | ## Pose model (WebView only) These flags exist on the hosted page. The **SDK rejects** them as `features` (`feature_not_supported`). On the SDK, BlazePose is `options.model = 'blazepose'` (light / web packages only). | Param | Default | Role | | ---------------- | ------- | --------------------------------------------- | | `blazepose` | `false` | Use BlazePose on the hosted page (plan-gated) | | `poseBackend` | `webgl` | `webgl` or `wasm` | | `runInWorker` | `true` | Worker inference | | `poseEngine` | `tfjs` | Pose runtime | | `mediapipeModel` | `lite` | MediaPipe model when BlazePose is on | ## Common URLs Live exercise: ``` https://app.posetracker.com/pose_tracker/tracking?token=YOUR_API_KEY&exercise=push_up&skeleton=true ``` Keypoints only (no reps): ``` https://app.posetracker.com/pose_tracker/tracking?token=YOUR_API_KEY ``` Paid streams + overlay: ``` https://app.posetracker.com/pose_tracker/tracking?token=YOUR_API_KEY&exercise=shoulder_roll&skeleton=true&keypoints=true&angles=true&progression=true&placementOverlay=true&timer=3 ``` Jump analysis (height required): ``` https://app.posetracker.com/pose_tracker/tracking?token=YOUR_API_KEY&exercise=jump_analysis&userHeightCm=178 ``` ## Not on this URL | Name | Where it lives | | ---------------------------- | ---------------------------------------------------------------- | | `difficulty` | SDK `startExercise(id, { difficulty })` only — **not read** here | | `userExercise` / `reference` | WebView only — not on the npm SDK yet | | Overlay / timer / guide | WebView only — SDK hosts draw their own UI | | Pixel tracking | Separate product — not on this site | Leave undocumented query flags unset. ## Related * [WebView messages](/webview/messages) * [WebView vs SDK param map](/reference/features-plans#webview-param--sdk-map) **For LLMs:** WebView params live on `https://app.posetracker.com/pose_tracker/tracking`. Required: `token`. Optional: one of `exercise`, `userExercise`, `reference` (omit all for keypoints-only). Do not document `difficulty` as a WebView param. Overlay/timer params are WebView-only. `userExercise` and `reference` are WebView-only. [https://docs.posetracker.com/webview/query-params](https://docs.posetracker.com/webview/query-params)
