Add Gateways to the Process

This tutorial demonstrates how to make a process more flexible using BPMN 2.0 exclusive gateways, routing execution based on dynamic conditions.

​

Add two gateways

Open your process in the Camunda Modeler. Insert a gateway (diamond shape) between the start event and the service task. Position a second gateway after the user task. Adjust the sequence flows to connect these elements appropriately. Name the new elements clearly:

​

Configure the gateways

Select each outgoing sequence flow and configure its condition in the properties panel: <1000 € flow — set Condition Type to Expression and enter ${amount<1000}: >=1000 € flow — ${amount>=1000}: Yes flow — ${approved}: No flow — ${!approved}: These conditions use the Unified Expression Language to evaluate the gateway.

​

Deploy the process

Use the deploy button in the Camunda Modeler to publish your updated process.

​

Work on the task

Navigate to Tasklist at http://localhost:8080/camunda/app/tasklist/ and authenticate with the demo credentials. Start a new instance and set variables via the generic form, using an amount ≥ 1000 to trigger the approval task. Complete the task by checking the approved checkbox. Test various scenarios, including rejecting payments and creating instances with amounts under 1000.
