Overview

When we show how easy it is to add web services to your FileMaker Solutions people always say – WOW, That's cool! We have taken the time to make it as easy as possible. If you can write FileMaker calculations, you can interact with Web Services – yes it really is that easy.

In 3.0 we have made significant changes in this new release.

• We have added REST support so you can integrate to any REST based service.
• XPATH is built right into the product that means that getting a list of results is extremely powerful. No loops to write - just a simple XPATH statement and presto a list of results from any xml result. Say goodbye to complex text parsing calculation and welcome to the power of XPATH.
• Another time saving feather is the ability to load the WSDL from a url. This allows you to work seamlessly from client once you have hosted your file on server.
• Encode and Decode Base64 - if you need to send your service provider a file or maybe they custom generated an image or pdf that you would like to download, then this feature will allow you to do just that.

Version 3.0 is a very exciting release because there are more and more WSDLs that we are able to parse and have been working closely with the open-source project to enhance and extend it.

Another very exciting opportunity in the FileMaker community is that 360Works recently announced the release of Web Services Manager. What this tool allows you to do is to expose your FileMaker scripts as WSDL functions. Combine the ability that 360Works provides in being able to publish your FileMaker scripts as Web Services, and our plug-in which lets you harvest those functions and interact with that particular web service and now you have opportunities to build light weight, non-persistent connections.

Dynamically loading functions is very cool, but the fact that a simple calculation can be getting results from Google, getting a shipping rate from FedEx, or looking up statistics for a particular neighborhood is even more exciting. The possibilities you can offer your customers are innumerable.

Before we dive into each of the functions, it is important to understand how to distinguish the default functions from the functions that you'll be using when you interact with a web service. If no WSDLs are loaded, the only functions that will show up are the default functions. We'll explore each one of these in detail in the default functions area.

Default functions. Note: default functions appear at the top of the list and are prefixed with an underscore.

These functions perform various tasks. Register the plug-in, get the version, set preferences, get preferences, load WSDL functions, and unload WSDL functions. A good analogy might be to think of the Web Services Plug-in much like a car, and WSDLs like gas - so without gas you car can't go anywhere. In an analogous way, without any WSDLs, your database will not be interacting with any outside services.

“WSDL or Web Services Description Language is 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”. - soaprpc.com
