🛠 Step 1: Create User Task in BPMN

Add a User Task in BPMN modeler.

Example:

Start Event → User Task → Service Task → End Event

BPMN XML Example

<bpmn:userTask id="approveOrder" name="Approve Order">
  <bpmn:extensionElements>
    <zeebe:taskDefinition type="io.camunda.zeebe:userTask" />
  </bpmn:extensionElements>
</bpmn:userTask>

---

🛠 Step 2: Configure Task Assignment

In Camunda 8, assignment is done using:

• assignee

• candidateGroups

• candidateUsers

Example

<zeebe:assignmentDefinition assignee="demo" />

OR group assignment:

<zeebe:assignmentDefinition candidateGroups="managers" />

Now only that user/group will see the task.

---

🛠 Step 3: Add Task Form

Camunda 8 uses Form Builder.

Create form in Modeler → Forms → JSON form schema.

Example Form JSON

{
  "type": "default",
  "components": [
    {
      "label": "Approved",
      "type": "checkbox",
      "key": "approved"
    },
    {
      "label": "Comments",
      "type": "textfield",
      "key": "comments"
    }
  ]
}

Attach form to task:

<zeebe:formDefinition formKey="approval-form" />

🛠 Step 4: Deploy Process

Deploy using Modeler or CLI.

After deployment:

Open Tasklist:

Login → demo / demo

You will see the task.

---

🧪 Step 5: Complete Task

1. Start process instance

2. Open Tasklist

3. Claim task

4. Submit form

Process moves to next step automatically.
