API's for Address Validation, Direct Mail Automation, and Mail Tracking

What is an API? 

Application program interface (API) is a set of routines, protocols, and tools for building software applications. An API specifies how software components should interact. Additionally, APIs are used when programming graphical user interface (GUI) components. In the simplest terms, APIs are sets of requirements that govern how one application can talk to another.

How do APIs Work?

APIs expose some of a program’s internal functions to the outside world in a limited fashion. That makes it possible for applications to share data and take actions on one another’s behalf.  APIs simplify all of this by limiting outside program access to a specific set of features—often enough, requests for data of one sort or another.   For example, AccuZIP's Direct Mail RESTful API exposes Web Service CASS™ Certification, NCOALink® (COA), Duplicate Detection, FCM/STD Presort, Mail Tracking and Reporting and EDDM® Mailing List Creation to outside applications. Think of APIs as doors or windows. APIs clearly define exactly how a program will interact with the rest of the software world, saving time, resources and potentially nasty legal entanglements along the way. AccuZIP's APIs come with complete documentation, technical support, and training.

I have gotten exceptional customer service from one of your employees. He has been unbelievably helpful onboarding me onto the software and he has taken the time to answer all of my questions and help me set up a lot of stuff that I needed to set up. He has gone above and beyond and has been extremely helpful and knowledgeable about the product. So far I love the product.
