SOAP vs REST API: Which is Better?

What are the main differences between SOAP and REST APIs?

SOAP (Simple Object Access Protocol) is a protocol that uses XML for message format, while REST (Representational State Transfer) is an architectural style that can use various formats like JSON, XML, etc. SOAP is more rigid and has built-in error handling, whereas REST is more flexible and easier to use.

Which one is more secure, SOAP or REST?

SOAP is generally considered more secure due to its built-in security features like WS-Security, which provides message integrity and confidentiality. REST can be secured using HTTPS, but it doesn't have the same level of built-in security.

When should I use SOAP instead of REST?

You should consider using SOAP when you need high security, ACID-compliant transactions, or when working with legacy systems that require it. REST is better for web services that require scalability and flexibility.

Can you give me an example of a use case for REST?

Sure! A common use case for REST is a web application that needs to interact with a server to fetch user data, like a social media app retrieving user profiles or posts.
