SOAP (Simple Object Access Protocol)

SOAP (Simple Object Access Protocol) is a protocol used for exchanging structured information in the form of XML messages between web services over the internet. SOAP defines a set of standards for message format, envelope structure, header elements, and transport protocols to enable interoperability and communication between distributed systems. SOAP-based web services use HTTP, SMTP, or other transport protocols for message exchange and rely on XML-based messaging formats for data representation and serialization.
