Build APIs and expose APIs for external useĪPIs have potential to add value to your business for customers and employees alike.To get the most out of APIs, businesses use APIs in the following ways: Business Case for APIsĪPIs expand the capabilities and functionalities you can offer, without putting a ton of resources behind integrations.
The point is that you can obtain the output you need in a form that’s easy to parse within the language you need for your application. You can find REST-based Web services that output the data in Command Separated Value (CSV), JavaScript Object Notation (JSON) and Really Simple Syndication (RSS). Unlike SOAP, REST doesn’t have to use XML to provide the response. REST uses four different HTTP 1.1 verbs (GET, POST, PUT, and DELETE) to perform tasks. SOAP relies solely on XML to provide messaging services, while REST offers a more lightweight method, using URLs in most cases to receive or send information. Just like a webpage is rendered, APIs can use HTTP requests to get information from a web application or web server.ĪPIs are typically categorized as either SOAP or REST and both are used to access web services. Each API has documentation and specifications which determine how information can be transferred. An API essentially provides the language and contract for how two systems interact. An Application Programming Interface (API) allows two systems to communicate with one another.
