SOAP

SOAP (Simple Object Access Protocol) is a protocol specification for exchanging structured information in web services using XML. It defines a messaging framework that allows programs running on disparate operating systems to communicate via HTTP and other protocols. SOAP APIs are known for their strict standards, built-in error handling, and support for complex operations.

Also known as: Simple Object Access Protocol, SOAP API, SOAP Web Services, XML Web Services, WS-*

Why learn SOAP?

Developers should learn SOAP for enterprise-level integrations, financial services, or legacy systems where reliability, security, and transactional support are critical. It is particularly useful in scenarios requiring ACID compliance, such as banking transactions or healthcare data exchanges, due to its WS-* standards for security and reliability.
