> ## Agent Instructions
> Trackstar is a unified REST API for WMS, cart, and carrier systems. Base URL: https://production.trackstarhq.com. There is no SDK; call the API with plain HTTP.
> Send x-trackstar-api-key on every request. Endpoints scoped to one connection also need x-trackstar-access-token. Read both from environment variables and never print them.
> Reads return data Trackstar has already synced from the connected system. Writes (POST, PUT, PATCH, DELETE) are forwarded to the connected system immediately.
> A new connection has no data until its initial sync finishes. Wait for the connection.historical-sync-completed webhook, or poll GET /connections/{connection_id} and check historical_sync_completed.
> List endpoints page with page_token and next_token (limit is capped at 1000). Repeat every filter on every page. Filters use field[operator]=value, for example created_date[gte]=2026-01-01T00:00:00Z.
> Write bodies must not contain null or empty strings; omit the field instead. Call GET /integrations/{integration_type}/{integration_name}/write-info first to learn the exact fields an integration accepts.
> To test without real credentials, POST /sandbox/generate-sandbox/{wms|cart|carrier} with the API key returns a sandbox access token. Start at https://docs.trackstarhq.com/how-to-guides/build-with-ai.md and install the skills with: npx skills add https://docs.trackstarhq.com

# Welcome to Trackstar!

> What Trackstar is and how to start building on the unified WMS, Cart, and Carrier API

Thank you for your interest in Trackstar! If you have any questions, don't hesitate to reach out to `support@trackstarhq.com`. Access to the API can be requested via [our website](https://trackstarhq.com).

### What is Trackstar?

Trackstar is a Unified API for Supply Chain Logistics.
We currently offer APIs for Warehouse Management Systems (WMS), Carts, and Carriers.

Integrate once with Trackstar, and you automatically get access to all of our supported integrations — no need to build and maintain individual connections to each system.

We provide a drop-in frontend authentication component that makes it easy to connect to your customers' end systems.

### How It Works

<Steps>
  <Step title="Connect">
    Your customer connects their system (WMS, Cart, or Carrier) via [Trackstar Link](/how-to-guides/trackstar-link), a [Magic Link](/how-to-guides/trackstar-link#sending-a-magic-link), or the [dashboard](https://dashboard.trackstarhq.com/connections). Each connection produces an **access token**.
  </Step>

  <Step title="Sync">
    Trackstar automatically syncs data from the connected system on a recurring schedule. An [initial sync](/how-to-guides/syncing-data#initial-sync-behavior) pulls historical data, and ongoing syncs keep everything up to date.
  </Step>

  <Step title="Build">
    Use the access token to read and write data through Trackstar's unified API. The same endpoints work across all integrations within a vertical.
  </Step>

### About Our Endpoints

The Trackstar API can be queried via HTTP REST endpoints. We follow standard HTTP authentication, response codes, and verbs.
Our API accepts JSON-encoded requests which are all documented here. All of our responses are returned as JSON.
All requests must be made via `https` and all requests should be made to `https://production.trackstarhq.com/`
