SOAP 1.1

SOAP 1.1 (Simple Object Access Protocol) is a protocol used for exchanging structured information between software applications over a network. It enables different systems, often built with diverse technologies, to communicate reliably by sending formatted messages called "XML." These messages can include requests for data or instructions for actions. SOAP 1.1 emphasizes standardization, making it easier for systems to understand each other, especially in web services. It supports complex operations, security, and transactions, serving as a foundation for enterprise-level communication between distributed applications.
