Important Note!
SOAP is done via POST, only with special XML markup in the post-body.

This XML is the definition of the web service, meaning its inputs, outputs, operations, and the like. Most likely, you will have another tool read this WSDL and make the operations available to you in your application. Whenever your utilities or IDE asks for a WSDL path to DOTS Address Geocode – US, you can provide this one.

Every web service has operations that it offers to subscribers – methods that do different work and return different output. Examining the link above, you will notice several of these operations available, which are described in detail later on.
