Difference between SOAP and REST Web Service in Salesforce.

Salesforce provides two types of web services. Below we are showing the difference between SOAP and REST Web Services which are as follows:

• SOAP web service is a protocol, whereas REST web service is an architectural style in Salesforce.
• SOAP web service stands for Simple Object Access Protocol and REST web service stands for Representational State Transfer.
• SOAP web service is not able to use REST because SOAP is a protocol, whereas REST web service can use SOAP web services because it is a concept and can use any protocol like HTTP, SOAP.
• SOAP web service uses services interfaces to expose the business logic and REST web service uses URI to expose business logic.
• SOAP web service defines standards to be strictly followed, whereas REST web service does not define too many standards like SOAP.
• SOAP web service defines standards to be strictly followed, whereas REST web service does not define too many standards like SOAP.
• SOAP web service requires more bandwidth and resource than REST and REST web service requires less bandwidth and resource than SOAP.
• SOAP web service defines its own security, whereas RESTful web service inherits security measures from the underlying transport.
• SOAP web service permits XML data format only, whereas REST web service permits different data format such as Plain text, HTML, XML, JSON etc.
• SOAP web service is less preferred than REST, whereas REST web service more preferred than SOAP.
• SOAP web service supports several protocols and technologies, including WSDL, WS-Addressing, and XSDs, but REST web service based implementation is simple compared to SOAP.
