Security: SOAP supports several security standards, including encryption, digital signatures, and authentication.Messaging: SOAP is a messaging protocol and defines a set of rules for exchanging structured data between different systems.Platform-Independent: SOAP is designed to work with any programming language or platform that supports XML and can send and receive HTTP messages.Protocol-Independent: SOAP is designed to work with any protocol that supports the transmission of messages over the internet, including HTTP, SMTP, and FTP.SOAP was later standardized by the World Wide Web Consortium (W3C) in 2003. SOAP was designed to provide a platform-independent way to exchange data between different systems over the internet. SOAP was first introduced in 1998 by Microsoft as a successor to Common Object Request Broker Architecture (CORBA) and Distributed Component Object Model (DCOM). SOAP is an XML-based protocol and is considered one of the earliest web service protocols. Simple Object Access Protocol (SOAP) is a messaging protocol used for exchanging structured data between different systems over the internet. With all this in mind, let's get into the details of how SOAP, REST and GraphQL APIs work. If you'd like a deeper intro to what APIs are, here's an awesome video about it. We'll also take a look at SOAP, which was quite popular some years ago and is still used in some niche sectors. The most popular ways to implement APIs nowadays are REST and GraphQl. That's why I think it's a very good idea for us as developers to get to know them well. Almost any kind of application will use a client-server model enabled by API communication. Having this set of rules, the client knows exactly what it has to require in order to complete a certain task, and the server knows exactly what the client will require when a certain action has to be performed.ĪPIs are absolutely everywhere in current software development. If you send C, I'll always respond D." and so on. It's like a contract between the two parts that says "If you send A, I'll always respond B. The way in which these two parts usually communicate is through an API (application programming interface).Īn API is nothing more than a set of defined rules that establishes how one application can communicate with another. The most important concept to remember about it is that clients request resources or services that the server performs. Most applications nowadays use a client-server model. Put simply, the client is the application that requests some kind of information or performs actions, and the server is the program that sends information or performs actions according to what the client does. In a recent article I talked briefly about two very important concepts in modern software development: the client-server model and APIs.Ĭlient-server is a model that structures the tasks or workloads of an application between a resource or service provider (server) and a service or resource requester (client). We're going to talk about the main kinds of APIs used nowadays (SOAP, REST and GraphQL), their characteristics, pros and cons, and situations in which each of them might be more beneficial. Hi everyone! In this article we're going to take a good look at APIs, a core concept in modern software development.
