SOAP vs Rest API - What's the Difference

SOAP (Simple Object Access Protocol) and REST (Representational State Transfer) are two different web services architectures used for exchanging data between systems.

Soap vs Rest API Differences:

Here are some differences between SOAP and REST.

Communication Style:

SOAP
REST
SOAP uses a messaging protocol that follows a strict set of rulesREST is more flexible and can use a variety of protocols including HTTP, HTTPS, and SMTP

 

Data Format Soap vs Rest:

SOAP
REST
SOAP typically uses XML (eXtensive Markup Language) as its data formatREST typically uses JSON (JavaScript Object Notation) or sometimes XML.

Interface Definition:

SOAP
REST
SOAP uses WSDL (Web Services Description Language) to define the interface between the client and the server.REST uses HTTP methods (such as GET, POST, PUT, DELETE, etc.) to define the interface.

Error Handling:

SOAP
REST
SOAP has a standardized error handling model that includes error codes and fault messages.REST typically returns HTTP error codes (such as 404 Not Found) to indicate errors.

Caching:

SOAP
REST
SOAP does not support caching.RESTful services can take advantage of browser caching, which can improve performance.

Statelessness:

SOAP
REST
SOAP maintains a state between requests.REST is stateless, meaning each request contains all the information necessary to complete it.

Performance:

SOAP
REST
SOAP can still be a reliable and effective web service architecture for certain applications, especially those that require strong security or transactional support.REST is generally considered faster and more lightweight than SOAP, as it uses less bandwidth and has less overhead.
