Async Service Task

We have a requirement where my service task has to trigger an API to perform some operations and wait indefinitely until it gets a signal/async-event that the operation is successful and it can now move to next task.

Not sure if merely making an service task as async will help. What could be the better approach?

Hi Amit,

Making task async does not make service call asynchronous (see http://activiti.org/userguide/index.html#bpmnConcurrencyAndTransactions)

Use:
<br>Activiti<br><br>start -> service call&nbsp; &mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;> intermediate message/signal -> end<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /\&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /\&nbsp; <br>&mdash;&mdash;&mdash; |&nbsp;&nbsp;&nbsp;&nbsp; |&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;|&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; \/&nbsp;&nbsp; answer immediately&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; take request &mdash;&mdash;&mdash; process request&nbsp; &mdash;&mdash;&ndash; send signal/message to activiti&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>called system<br>
