How to send signal to particular instance along with details?

Question

I have 2 process P and Q where I am trying to throw signal (globally)from process P and catching signal at Q. When there are multiple instances, for example: In process P -process instances P1, P2 and in process Q -process instances Q1 and Q2. If I throw signal from one process instance that will be caught by multiple instances of other process.

For example, If I throw signal from Q1 that will be caught by all the instances of P [P1,P2].

I tried following ways:

1] RuntimeService.signalEventReceived(String signalName, String executionId);

With this method, I can invoke particular instance but, was not able to pass the details[data].

2] POST runtime/signals { "signalName": "My Signal", "tenantId" : "execute", "async": true, "variables": [ {"name": "testVar", "value": "This is a string"}

] }

With this api, I was able to get details[data] by passing variables, but was not able to invoke particular process instance.

Is there any way to send signal to particular instance along with details?

Thanks & Regards,

You can try to use this method

void signalEventReceived(String signalName, String executionId, Map<String, Object> processVariables);
