A Web Service is a communication method over two electronic devices over the Web. The final goal of having native Web Services on Microsoft Dynamics NAV is to make it easy for other systems to integrate with Microsoft Dynamics NAV.
 
W3C defines Web Services as a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL).
 
There are some concepts we need to know before continue to talk about Web Services:
 
WSDL-> W3C defines a Web Service Description Language as an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint. Related concrete endpoints are combined into abstract endpoints (services). WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate, however, the only bindings described in this document describe how to use WSDL in conjunction with SOAP 1.1, HTTP GET/POST, and MIME.

SOAP-> Simple Object Access Protocol provides a simple, extensible, and rich XML messaging framework for defining higher-level application protocols offering increased interoperability in distributed, heterogeneous environments. This was the only protocol supported for Microsoft Dynamics NAV 2009.  Microsoft Dynamics NAV 2013 also supports a new protocol called ODATA.



For Detail see Video on how to expose pages and codeunits on webservice.

Web Services were introduced on Microsoft Dynamics NAV 2009 and they were supported through Web service–enabled pages and codeunits. With proper authentication and authorization, external systems can read and write data on pages and call codeunits as XML Web services using SOAP over HTTP and having their interfaces exposed in a WSDL. When you publish pages and codeunits as Web services from Microsoft Dynamics NAV, they are immediately available for Web service requests over the network.

On Microsoft Dynamics NAV 2013, Web Services created for Microsoft Dynamics NAV 2009 remain, and some new features and capabilities have been added.

In this document we will cover Web Services on Microsoft Dynamics NAV and we will mainly focus on new features added for Microsoft Dynamics NAV 2013.

There is a vast amount of documentation created for Microsoft Dynamics NAV 2009 Web Services release that still applies to Microsoft Dynamics NAV 2013 and thus we will not cover what has already been written.

If this is your fist approach to Microsoft Dynamics NAV Web Services please consider going through these links as mandatory so they will show you valid lessons for Microsoft Dynamics NAV 2013 release.

Video Download is available on how to expose pages and codeunits on webservice.
