This document compares SOAP and REST web services protocols for selecting the right protocol. It provides a flowchart to guide the decision. REST should be used unless there is a specific reason to use SOAP. REST is simpler, faster, more scalable and supports web/mobile clients better. SOAP supports more transports, sessions, transactions, and enterprise security features. The document lists advantages of REST like simplicity, wider data formats support, and performance/scalability. It also lists advantages of SOAP like wider transport support, session/state support, transaction support, and better error handling.

- 3. Guiding Principle (Rule of Thumbs) • Use REST unless there is a specific reason to use SOAP • REST is easier, faster, more scalable and provide better support for web browsers and mobile clients. • There are some unique & distinctive advantages of using SOAP for certain use-cases but those use cases are very small % of overall use-cases for implementing web services. • A flow-chart is provided in the next slide to guide with determining if you should use SOAP or REST protocol for your web services
- 4. Flow-chart for selecting right web services protocol
- 5. Explanation of Flow chart decisions criteria • REST only supports HTTP Transport • RESTful services does not maintain state • RESTful Web service is not ACID compliant and does not support two-phase commit across transactional resources
- 6. Explanation of Flow chart decisions criteria • REST services communications can be secured over HTTP by using an SSL certificate. SOAP supports SSL as well as more enterprise security features by it’s support for WS- Security • Rest does not support a standard messaging system and delegates clients to deal with communication failures by retrying. On the other hand, SOAP supports built in successful/retry logic and provides end-to-end reliability (sometimes through SOAP intermediaries) (continued )
- 7. Advantages of REST services over SOAP Criteria Advantage Simplicity/Ease of use REST uses standard HTTP and it is much simpler for creating web services clients and for API development as well. All languages have methods to call HTTP GET, PUT etc. Wider support for Data interchange formats REST allows many data formats like XML, JSON etc. where as SOAP only permits XML. JSON is usually a better fit for data interchange and it parses much faster. Extended Client Support REST allows better support for browser and mobile clients due to it’s support for JSON Performance & Scalability REST has better performance and scalability features. Read operations in REST can be cached whereas SOAP based reads cannot be cached
- 8. Advantages of SOAP services over REST Criteria Advantage Wider support for Transport Protocol It can be used over any transport protocol such as TCP, HTTP, SMTP or even MSMQ Session/State Support It is easy to configure session support for SOAP Transaction Support SOAP can support distributed two-phase commit transactions by implementing WS-Atomic standards Better Support for Enterprise Security Provide more choices for implementing security beyond the standard SSL support by implementing WS-Security standard Better error handling and guaranteed delivery REST only supports HTTP error handling but SOAP provides more robust error handling including user defined error handling and a documented contract for error responses. SOAP can also provide support for guaranteed delivery by implementing WS-Reliable standards.
