Here is a Spring Boot RestController that starts the crm-warranty process, queries for and starts the first task while assigning a salesPerson variable:


@RestController
@RequestMapping("/demo")
public class DemoRestController {

    private final RuntimeService runtimeService;
    private final TaskService taskService;

    public DemoRestController(RuntimeService runtimeService, TaskService taskService) {
        this.runtimeService = runtimeService;
        this.taskService = taskService;
    }

    @PostMapping("/{salesPerson}")
    public String startDemoProcess(@PathVariable("salesPerson") String salesPerson) {
        ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("crm-warranty");

        Map<String, Object> variables = new HashMap<>();
        variables.put("salesPerson", salesPerson);

        List<Task> tasks = taskService.createTaskQuery().processInstanceId(processInstance.getId()).list();

        tasks.forEach(task -> taskService.complete(task.getId(), variables));

        return processInstance.getId();
    }
}

I tested it by adding a kadir user to flowable-idmm, adding this controller to the flowable-rest WAR, and executing:

curl -X POST localhost:8080/flowable-rest/demo/kadir -u admin:test

The next task is then visible in flowable-task:
