We have already discussed Representational State Transfer Application Programming Interface.
SOAP - Simple Object Access Protocol
1. A protocol.
2. It has got very tight security and strict rules.
3. Messages carry a lot of information. That's why they need more bandwidth and resources.
4. You can use only XML format, where XML stands for eXtensible Markup Language.
5. It uses service interfaces. For example, WSDL (Web Service Description Language) is used to inform the Client about the functionality of a web service.
6. It is a protocol, cannot use REST.
7. Best when your application needs high reliability and tight security.
REST - Representational State Transfer
1. No official standard (just a concept). It is an architectural style.
2. Simple, not many standards, just HTTP protocols.
3. It mostly carries JSON messages like - {"name":"Neeraj","blog":"techNtoast"}. That's why it does not need much bandwidth.
4. You can use lots of formats like HTML (Hypertext Markup Language), XML, JSON (JavaScript Object Notation), plain text etc.
5. REST API takes the advantage of URL exposure. For example, an object representing the data of CRM or Customer Relationship Management, which is hosted on this URL - https://www.techntoast.com, I will go to https://www.techntoast.com/2019/08/crm-or-customer-relationship-management.html to access that data.
6. It is an architectural pattern, can use SOAP.
7. Best for stateless CRUD (Create, Read, Update, and Delete) operations.
