11/10/2023 0 Comments Soap vs rest vs jsonfree choice of the data format - it's up on you to decide whether you can use plain TXT, JSON, XML, or even create you own format of data.lightweight (in all means: no server- nor client-side extensions needed, no big chunks of XML are needed to be transfered here and there). Here are my cons'&'pros for both: REST Pros The only difference between SOAP and REST services (no matter whether using JSON) is that SOAP WS always has it's own WSDL document that could be easily transformed into a self-descriptive documentation while within REST you have to write the documentation for yourself (at least to document the data structures). It was nice to use it, nice to learn it, and it is beautiful we can use JSON now. Nowadays SOAP is a complete overkill, IMHO. If you are creating a client application and your server implementation is done with SOAP then you have to use SOAP in client side.Īlso, see: Why use SOAP over JSON and custom data format in an “ENTERPRISE” application? JSON doesn't have a standard way of doing this. In short, SOAP has a way of specifying the data structure in a maturely formatted document (WSDL). JSON has similar ways of specifying this data structure - a JavaScript class comes to mind as the most common way of doing this - but a JavaScript class isn't really a data structure used for this purpose in any kind of agnostic, well established, widely used way.See W3C specification: Web Services Description Language "Cart is a collection of Products and each Product can have these attributes, etc." A well put together WSDL document really has this nailed. SOAP has an industry-mature way of specifying that data will be in a certain format: e.g.I don't mean how the data is encoded and passed, but how the data formatted format is defined, the data model. With every JSON setup, you're always coming up with your own data structure for each project. There is one big reason everyone sticks with SOAP instead of using JSON.Recently, a lot of new APIs are being developed as ODATA only APIs to prepare for the future challenges of scalability and performance.I found the following on advantages of SOAP: ODATA can be assumed as the youngest child of the HTTP family with newest and greatest capabilities but lacks in wide adoption. This is the newest member of the family for data exchange built on architectural pattern of REST. OData - It has been adopted by a lot of companies including SAP, IBM, Salesforce, Tableau, Databoom, Progress, Red Hat and Dell. REST is more suitable for Apps requiring moderate security but high scalability for example Social sites like Twitter, Facebook, Instagram etc. Similarly, REST is a step between SOAP and ODATA and can be assumed as the middle child of the HTTP family. REST is an architectural pattern that ODATA uses as well. This means that developers have no need to install additional software when creating a REST API. REST API - While REST APIs were designed to take advantage of existing protocols & used over any protocol, when used for web APIs it typically takes advantage of HTTP. SOAP is more suitable for Enterprise Apps requiring high Security, distributed environments like Payments and financial applications. SOAP has been there for a while and can be assumed as the eldest son of HTTP family. However, lately companies have started looking at REST/Odata services due to its light wait, extensibility, navigational properties at resource level. That is why it is perfect for usage across the web applications. SOAP API - It is built upon the XML specification & works with the HTTP protocol. For simplicity, we can assume it to be the Father of transport protocols with Children like SOAP, REST and ODATA HTTP - HTTP is the native transport layer protocol that can carry plain, soap, json or ODATA messages. SOAP, REST, ODATA and HTTP protocols are the most important current Web service APIs.
