A niche vertical of APIs in which there are multiple web services to choose from is package tracking. There are more than 70 tracking and shipping APIs listed in the ProgrammableWeb directory with many of the biggest global package shippers represented including FedEx, DHL and UPS.
These are typically designed for commercial applications that need to integrate tracking, address verification, label printing and rate calculations. Here's a quick overview of 7 options available to developers wanting to track their packages.
- FedEx API: This package tracking API has been integrated into a variety of third-party shipping tools (They highlight case studies from Cover Shield and Webgility). Their new FedEx Web Services is replacing the soon to be retired FedEx Ship Manager API. Uncertified developers have access to standard services such as package tracking and FedEx locator. More advanced services are available to developers that submit to a certification process. Note that their site provides little in the way of public documentation.Track this API
