SOAP Header

A SOAP header is a part of an XML message used in web services to include additional information needed for processing the request or response. Think of it as the "cover letter" that accompanies a formal letter, providing details like authentication, transaction info, or routing instructions. It doesn't contain the main data but delivers essential context, ensuring the message is handled correctly and securely by the receiving system. This allows different systems to communicate efficiently while maintaining important metadata separately from the main message content.
