> ## 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
