What are the different types of APIs?
There are three types of application programming interfaces: REST, SOAP, and ASP.NET. SOAP — Simple Object Access Protocol — connects various platforms through HTTP and XML, and integrations made with this interface type are less manageable, so developers have started moving away from it. REST is an abbreviation for Representational State Transfer, and it's independent of a specific protocol so that users can build smooth and flexible integrations. ASP.NET functions as a form of REST developed around .NET technology. In most cases, you'll need to have a Windows Server to be able to employ it. Still, this platform is effortless and straightforward.
