Web Service Structure:
Web services are methods that integrate with other applications via the web, and encapsulate complex business logic. Web services are too large a topic to cover in this document, but Service Objects has developed its web services to be as easy to integrate and as accessible as possible.
DOTS Address Geocode – US is a public XML web service that supports SOAP, POST and GET operations.
The host path, or physical location of the web service is here:
The location of the WSDL, or Web Service Definition Language document, is here (This is also accessible via the "Service Definition" link.):
Service XML Request Help Page
Service JSON Request Help Page
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.
