Demonstration




Calling A Web Service







• Web Service invoked programmatically by PeopleCode

• For a synchronous message this would typically be code on a FieldChange or PageSave event




Calling A Web Service




• Contact Record has FieldChange PeopleCode for FieldChange




Calling A Web Service































1. Construct Request string

2. Make Synchronous Request Message call and receive results in the Response Message
3. Unravel Response Message and display appropriate fields














Call Web Service
Demonstration




Call Web Service
Example




• User updates the value of the data in the Zip Code field
• Field Change PeopleCode triggers to call the Web Service to return the Weather information for that Zip code
