How to use web service consumer
Download as PPTX, PDF0 likes236 views
The document discusses how to use a Web Service Consumer in Mule applications to consume SOAP web services when no specific connector exists. It provides an example Mule flow that defines a web service consumer configuration, sets a JSON payload with a country code, transforms it to XML, and calls the GetCitiesByCountry operation to get cities for that country from the GlobalWeather web service. The output cities are displayed in the browser by triggering the flow at a localhost URL.

How to use web service consumer
- 1. How to use Web Service Consumer 26-05-2015
- 2. Abstract • The main motto of this PPT is How to use Message Enricher in our applications.
- 3. Introduction • When developing applications with Mule, users often need to be able to consume a SOAP Web service to acquire data from an external source. In the best case scenario, you can use an existing Anypoint Connector in your Mule application to connect to a specific service provider, such as Zuora or Avalara. However, where no service-specific connector exists to facilitate the connection, the quickest, easiest way to consume a Web service from within a Mule application is to use the Web Service Consumer.
