SOAP vs. REST APIs: The Key Differences

API:


API stands for Application programming interface. API is a piece of software in which communication and data exchange from one application to another. It’s a middle layer between database and user interface.


When talking about API architectures, it’s common to compare SOAP vs. REST, two of the most common API paradigms. SOAP is a protocol, and REST is an architectural style. REST APIs access a resource for data (a URI); SOAP APIs perform an operation.


The most widely popular tool for API testing in the world, SoapUI allows you to test REST and SOAP APIs with ease – as it has been built specifically for API testing.





 




PROS AND CONS OF SOAP:


PROS:

  • SOAP is a great tool to have when working with multiple extensions is the aim. It makes creating highly functional apps a little strenuous task.

  • SOAP is a protocol-neutral protocol and can be accessed easily via HTTP, SMTP, TCP, and many other kinds of application protocols. This also means a wide range of users can bring it into practice.

  • It serves as a comprehensive resource to learn about API consumption. It makes API development a seamless experience.


Cons:

  • It uses XML for payload data transfer. XML takes longer than usual time for this job

  • SOAP has complicated syntax. It can only work with XML


PROS:

  • It doesn’t bank upon any other client-server context for information storing. Because of this, it speeds up the entire process.

  • APIs developed using REST are highly flexible and can collect the server data in multiple formats.

  • In REST, responses are catchable.


Cons

  • REST-based applications are also very cramped to the HTTP Protocol which restricts them.

  • REST is easy to work with at every front.
