SOAP

SOAP (Simple Object Access Protocol) is a messaging protocol for exchanging structured information in web services using XML over HTTP and other transport protocols. It provides built-in standards for security, transactions, and reliability, making it a common choice for enterprise integrations and legacy system communication.
