Thinking of trying the Pitney Bowes Tracking API? There are a number of points to consider, many of which will affect cost, performance, and integration times.
First off, the Pitney Bowes Tracking API is a SOAP / XML API. This can introduce problems of its own when attempting to parse responses from their API.
Additionally, Pitney Bowes doesn't provide any supported client libraries. Regardless your programming language, you'll need to write your own client library.
Fortunately, there are alternatives to such a slow integration process. EasyPost is a multi-carrier API with quick technical support and client libraries for all major programming languages.
