Track parcels (billable)

Track up to 5 parcels at once. Average response time 5 seconds per item. Supports 500+ carriers including USPS, UPS, FedEx, DHL, and more.

When to use this endpoint: Use /v2/track for on-demand, one-off lookups — for example, when a customer checks their order status on your website.

For continuous monitoring, use Webhooks instead. If you need to keep your database in sync with delivery status (e.g., updating order records, triggering notifications), register a webhook subscription via /v2/webhooks/register with recurring: true. The webhook approach is far more efficient — instead of polling repeatedly, you receive a push notification only when the status actually changes.

Rate Limits: Each API key has per-minute and per-month request quotas based on your plan. When exceeded, the API returns HTTP 429. See response headers X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset for current usage.
