Shipping API & Developer FAQs
What is a multi-carrier shipping API for eCommerce?
A multi-carrier shipping API connects your store or platform to multiple shipping carriers (e.g., UPS, FedEx, USPS, Royal Mail, Australia Post, or DHL Express) through a single integration. Instead of connecting, maintaining, and switching between separate carrier connections or interfaces, you can automatically compare rates, print labels, track packages, and generate tax, duty, and customs documents. When simplifying shipping operations or monetizing shipping capabilities, Easyship can act as the technical link or integration layer between your shopping cart, marketplace, or platform and the respective shipping carriers.
How many shipping services can I access with Easyship's API?
Easyship provides instant access to 550+ courier services across 200+ countries and territories through a single API integration. This includes all major global carriers such as UPS, FedEx, and DHL Express, a long list of regional specialists, and local postal services worldwide, such as USPS, Australia Post, Royal Mail, or Canada Post. You can also connect your own negotiated business accounts and use those rate cards alongside Easyship's discounted pricing—all through the same API.
How scalable is Easyship's API for high-volume retailers?
Our API handles billions of calls with 99.99% uptime. Whether you ship 50 or 50,000 packages daily, our infrastructure scales automatically, delivering reliable, predictable performance for high-volume fulfillment. Companies like eBay and Shopify use Easyship to handle peak season holiday shipping surges.
Is Easyship's shipping API reliable for Enterprise brands and platforms?
Yes, absolutely! We maintain 99.99% uptime with SOC certification and GDPR compliance. Our multi-carrier infrastructure includes automatic carrier redundancy, 24/7 enterprise support, and real-time monitoring. Trusted by eBay, Shopify, and American Express for seamless fulfillment services, we proactively manage carrier outages and industry shifts so your shipping never stops.
How does Easyship handle connecting your own carrier accounts, billing, and reconciliation?
Connect your own carrier accounts to access your negotiated rates and generate labels through our API. Easyship provides full cost visibility with itemized billing reconciled back to each shipment. Choose direct carrier billing or white-label centralized billing under your account. Our API provides flexible billing and reconciliation options for Enterprise depending on the exact requirements.
Does Easyship offer white-label shipping services for brands and platforms?
Yes, our API integration is completely flexible. Remove all Easyship branding from your shipping flow. Use your own logo, branding, domain, and messaging to deliver an on-brand shipping experience. Offer discounted rates, tracking, and allow customers to pay for postage without leaving your platform—or mark up shipping costs to generate transactional revenue. Manage unlimited customer accounts with isolated billing. Explore all the custom implementation options available on our Enterprise plans, with dedicated onboarding and support.
What white-label shipping capabilities can be implemented using Easyship's API?
Ready to turn shipping into a profit center? Offer a range of shipping services under your own brand and platform user experience. Customize tracking pages with your logo, embed rate calculators in your checkout, and send branded delivery notifications. Even set your own shipping prices and keep the markup as revenue or pass on discounted rates. With an end-to-end white-label experience, your customers never see Easyship—just your brand. Perfect for platforms and marketplaces wanting to monetize shipping, differentiate their app, or create a consistent user experience.
