If you're needing to integrate shipping into your site or fulfillment operation, EasyPost allows you to connect with all the major carriers in one simple integration. Instead of bulky, expensive software that requires lots of manual labor, EasyPost allows you to connect to USPS, UPS, FedEx, DHL and more at a fraction of the cost of other shipping integrations. What's more, it takes 1/10th the time to integrate.

When doing a shipping integration there are roughly two options:

  • Plugins
  • APIs

Depending on your ecommerce or fulfillment platform, there are many plugins that will manage your shipping integration. With EasyPost, we offer plugins for:

Using these will save you significant amount of time on a daily basis. These will help you automate shipping label purchases, tracking, and more.


If you're doing more than 500-1000 shipments per month, APIs are by far the best option for shipping integrations. APIs allow you to completely automate almost all of the shipping functions. Pull back accurate rates, purchase shipping labels, generate customs forms, provide tracking information to customers, and more.

Each of the major shipping carriers has their own API. Here are links to some of them:

However, if you want to spend less time integrating shipping and more time building your business, EasyPost is a great option. The EasyPost API provides access to all those carriers, plus DHL and others.

Another major issue is that the carrier APIs often have out-of-date documentation and mismatched test and production servers.

Want to give EasyPost a try before you delve into the carrier APIs directly? You can take a look at our EasyPost API Documentation to see how simple the integration is.
