PoseTracker API query parameters

PoseTracker runs a single tracking engine for both integration modes (Real-time + Uploads).

Real-time tracking (camera / webcam)

GET https://app.posetracker.com/pose_tracker/tracking?QUERY_PARAMS

Upload tracking (video or image)

GET https://app.posetracker.com/pose_tracker/upload_tracking?QUERY_PARAMS

Both endpoints support the shared parameters below.

---

1. Authentication

token (required)

Type: string Required: yes

Your PoseTracker API key.

Used to:

• authenticate requests

• apply usage limits based on your plan

Example

?token=YOUR_API_KEY

---

2. Platform Configuration

isAndroid

Type: boolean Required: only for Android apps

Description:

PoseTracker requires this parameter when running inside an Android WebView.

Android WebViews handle camera permissions differently, and this flag ensures PoseTracker uses the correct runtime behavior.

Usage:

?isAndroid=true

For:

• Android mobile apps

Do not use for:

• iOS apps

• web browsers

• desktop environments

Example

https://app.posetracker.com/pose_tracker/tracking?isAndroid=true

---

3. Movement Tracking Mode

PoseTracker supports two movement tracking modes.

Only one of these parameters should be used at a time.

---

exercise

Type: string

Required: no

Description:

Selects a built-in PoseTracker movement.

Examples

exercise=squat
exercise=push_up
exercise=lunge
exercise=plank
exercise=jump_analysis

Built-in exercises provide:

• repetition counting

• form scoring

• posture validation

• recommendations

• progression signals

More info here: EXERCISE (optional)

---

reference

Type: string Required: no

Description:

UUID of a reference movement created in the PoseTracker dashboard.

When provided, PoseTracker compares the user's movement to this reference movement instead of using a built-in exercise.

This allows developers to track custom movements.

Example

reference=7f3c5a0d-9d84-4d15-9c5a-cc1e3a4b1baf

Example URL

https://app.posetracker.com/pose_tracker/tracking?token=YOUR_TOKEN&reference=REFERENCE_UUID

⚠️ exercise and reference cannot be used together.

When using reference, PoseTracker returns similarity metrics inside the reference_score field.

More details here: REFERENCE

---

4. Rep Filtering (Repetition Exercises Only)

minGrade

Type: string Required: no Default: not set

Allowed values:

A
B
C
D

Description:

Only count repetitions that meet a minimum form grade.

Example

minGrade=B

Counts reps graded:

A
B

Ignores reps graded:

C
D
F

Example URL

https://app.posetracker.com/pose_tracker/tracking?token=...&exercise=squat&minGrade=B

Applies only to repetition exercises.

Ignored for:

• duration exercises (plank, wall_sit)

• custom exercises (jump_analysis)

• reference tracking

Grades are returned inside the counter.form_score event.
