Configuring the Process Project from Which you Want to Call the REST Service

You can configure a task (Service Task, Send Task, Throw Message Event, Message End Event) in a process to call a REST Service.

1. Add a Service Task to your process, and configure it with a Service Type of REST Service.
   You can also configure the following to call a REST Service:

   • Send Task
   • Service Task
   • Message End Event
   • Send Task and Throw Message Event: you need to select Send One Way Request to activate the Implementation option "REST Service".
2. Select Operation: Select to select the REST service method. See Defining the Interface to an External REST Service.
   
3. Define any data fields needed for the call.
4. Map process data to / from the method parameters (see Defining Input and Output Mappings for more information).
