Hi,

I have added a boundary message event to a subprocess to sent an email upon reception. Like this:

 ![image](https://canada1.discourse-cdn.com/flex035/uploads/flowable/original/2X/9/998bca2d2a6a8b6ccf8037fa8a10418e366a836f.png)

Is there an easy way to get the executionId of the boundary message event activity? I want to expose it to the outside to be able to call it by HTTP using

```auto
PUT /service/runtime/executions/:executionId

```

Or an alternative way of doing it?

Thanks!

If you need a list of executions waiting for the message:

```auto
getRuntimeService.createExecutionQuery.messageEventSubscriptionName(...).list()

```

Regards
