Here I will make a discussion about similarities, differences, and an overview of SOAP API and REST API services.

What is REST API?

REST (Representational State Transfer) is another standard, made in response to the shortcomings of SOAP. Try to troubleshoot problems with SOAP and provide an easier way to access web services.

REST offers a lighter alternative. Many developers have found REST to be easy to use. REST (typically) uses a simple URL to make a request instead of XML. Although in some cases it may be necessary to provide additional information, most REST web services depend solely on the URL approach.REST will perform tasks with four separate HTTP 1.1 verbs (GET, POST, PUT, and DELETE).

REST response must not be in XML. You can find REST-based web services with data output in Command Separated Value (CSV), JavaScript Object Notation (JSON), and Very Simple Syndication (RSS). the point is, you can get the output you need in an easy-to-analyze format in whatever programming language you use.

What is SOAP API?

Simple Object Access Protocol (SOAP) is a standards-based web services access protocol that has been around for a long time. Originally developed by Microsoft, SOAP is not as straightforward as the acronym suggests.

SOAP messaging services are fully XML-based. SOAP was created by Microsoft to replace older Internet-incompatible technologies such as the Distributed Component Object Model (DCOM) and Common Object Request Broker (CORBA) architecture.

Because they rely on binary messaging, these fail.SOAP technologies use XML messaging, which works best on the Internet.

Microsoft sent SOAP to the Internet Engineering Task Force (IETF) for standardization after its initial release. WSAdressing, WSPolicy, WSSecurity, WSFederation, WSReliableMessaging, WSCoordination, WSAtomicTransaction, and WSRemotePortlets are just a few of the acronyms and abbreviations associated with SOAP.

Similarities of REST and SOAP

Although SOAP and REST both use the HTTP protocol, SOAP has a stricter collection of messaging models than REST.

SOAP rules are fundamental because without them we will not be able to achieve any degree of standardization. REST is a more versatile style of architecture because it does not require processing.

SOAP and REST both depend on well-defined rules that everyone has agreed to follow in the name of information exchange.

Benefits of REST

No expensive tools needed to interact with the web service

• Reduced learning curve

• Efficient (SOAP uses XML for all messages, REST can use smaller message formats)

• Fast (none extended processing required)

• Closer to other web technologies in design philosophy

Benefits of SOAP

• Language, platform, and transport-independent (REST requires the use of HTTP)

• Works well in distributed enterprise environments (REST assumes direct point-to-point communication)

• standardized

• Provides significant extensibility of precompilation in the form of WS * standards

• Built-in error handling

• Automation when used with some language products.
