What are the main differences between API and Web Service?

  • Although all APIs are Web services, but not all Web services are APIs.

  • Web services could not have all the specifications or be able to do everything an API can do.

  • On the other hand, an API can be exposed in several ways, a Web service can only communicate using SOAP, REST, and XML-RPC.

  • While APIs don’t require a network to function, Web services always require one.
