Web services allow invoking methods and fetching data on external web services which support the WSDL standard.
- To add a new service click plus ( + ) symbol in the web services list from the process designer dashboard.
- Enter the web service address in the URL field. (Example: http://www.webservicex.net/globalweather.asmx?WSDL )
- Currently only WSDL standard is supported, but other service types will be added in the next releases.
- After clicking on 'Ok' button, service is automatically discovered in couple seconds, and service methods are displayed on screen.
Rest based services do not have any meta description and there is no need to register or discovery before using. You can directly call any rest service with $Rest object.
Service discovery scans the available methods on service and automatically registers the web service xml data types in "External Xml Schemas". Web service data types can also be directly used in the process data model.
In example, "GetWeather" is a method in service and expects the "CityName", "CountryName" fields to invoke and return GetWeatherResult type. Gray box contains the example of a usage for scripting. Return value of the method may be a basic value or a complex data type. You may need to inspect the data type from external xml schemas.
Test Mode URL
This field is optional, you may leave it blank. If you want to use another service for testing environment, you can specify the URL of service. If the workflow instance is in test mode, this address is used automatically. Test and live service definition must be identical, otherwise unpredictable errors may occur.
Consuming SOAP Service
Calling Service from Scripts
After service is registered you can call the service from scripting environments including browser based client scripts.
var result = $Services.GlobalWeather.GlobalWeatherSoap.GetWeather({
CityName : 'Amsterdam',
CountryName : 'Netherlands',
});
Using Service Results as Data Source
You may also use the service methods to populate lists (for example DropDowns)
After service is registered add a new data source as "Web Service Query"
Click on "Edit" button to edit data source. Service method is now displayed on screen and specify input parameters.
Additional Options
All standard SOAP headers are automatically handled by system but in some scenarios you may need set additional SOAP headers transfer information.
While invoking service after specifying request body you may give secondary object to as headers body. If service definition has matching header by name, specified value is imported to the SOAP message.
var result = $Services.GlobalWeather.GlobalWeatherSoap.GetWeather({
CityName : 'Amsterdam',
CountryName : 'Netherlands',
}, {
MyHeader : 'MyHeaderValue'
});
Consuming Rest Service
Rest services does not provide any discovery information and dynamically invoked.
Please refer to $Rest page to get information for consuming a rest service.
