Unified responses
Work with a consistent JSON format instead of maintaining separate response models for every carrier.

How it works
From tracking number to useful shipment data.
Your application requests tracking data when it needs an update. Webhooks are not supported; use a polling schedule that fits your request allowance.

Frequently asked questions
What teams usually want to know.
Need help evaluating a custom integration? Contact our team directly.
Ask a questionWhich carriers are supported?
C2W supports UPS, USPS, FedEx, DHL Express, DHL eCommerce, OnTrac, UniUni and GOFO. Check your specific services and routes before migrating. Read the carrier integration guides for practical evaluation notes.
Does the API support webhooks?
No. Webhooks are not supported. Your server requests tracking data when needed; your application manages polling and any customer notifications.
Is there a free plan?
Yes. The Basic plan includes 5 requests per day with a hard usage limit. Paid plans start at $9.99/month. See all plans and request-budget examples.
Are limits based on shipments or requests?
The published allowances are API requests per day. Budget repeated calls for the same tracking number separately. Daily quotas and rate limits both apply; see your RapidAPI subscription for reset times and billing counters.
How fresh is the tracking information?
Each request retrieves the latest tracking status available from the carrier API. Status changes depend on when the carrier records and makes new shipment events available. Choose a polling interval that fits your workflow and request limits.
Do I need to send a carrier parameter?
The documented GET request uses a trackingNumber query parameter. It does not document a separate carrier parameter. Validate representative numbers from your services during evaluation.
Can I submit multiple tracking numbers?
The public reference documents one tracking number per request. For a batch workflow, contact C2W to confirm the available endpoint, maximum size, and quota accounting before implementation.
What happens when tracking data is unavailable?
Check the HTTP status before parsing JSON. Authentication failures, quota limits, and unavailable carrier data require different handling. The integration guide shows how to keep errors separate from shipment status.
Can you support custom requirements?
Yes. Discuss request limits, response fields, carrier-specific requirements, and billing directly with the founder. Custom scope, feasibility, timing, and cost are agreed individually.
Where do I get an API key?
Subscribe through the C2W TrackingPackage listing on RapidAPI. Keep your API key on your server and start with the API documentation.
