Endpoint /actionevent not working

[Cezary_Rynkowski]

Hey
What I'm trying to accomplish is to automatically send an errored state in response to a contentOffer.

I'm grabbing a Journey.qualifiedContentOffer event and trying to call the
api/v2/journey/deployments/{deploymentId}/actionevent
And here 2 things

1. where can I get the sessionId from? Looks like this code

ac('api.session.getId', (err, IdInfo) => {
        if (err) {
        // handle error
        return;
        }
        return IdInfo;
        });

generated a new sessionId and not the one I should use.

2. even if I manually take the sessionId from the ping, the call returns nothing.
   Example:

curl 'https://api.mypurecloud.com/api/v2/journey/deployments/xxxx-xxxx-xxxx-xxxx/actionevent' \
  -H 'Accept: */*' \
  -H 'Content-Type: application/json' \
  --data-raw '{"sessionId":"xxx","actionId":"xxx","actionState":"engaged"}'

From what I can see all events e.g. closing content offer uses a different API:

https://api.mypurecloud.de/api/v2/journey/deployments/xxx-xxx-xxxx/customers/xxxx-xxxx-xxxx/beacons?data=BASE64ENCODEDDATA&type=webactionevent

So how is it with this API, does it work at all?

Ok, let's ignore the 1st part of the question for now.

I am almost certain that the endpoint indicated in point 2 does not work at all. Using the endpoint

https://api.mypurecloud.de/api/v2/journey/sessions/web/recent?pageSize=20

I retrieve the last sessionId. I use it later in the request:

curl 'https://api.mypurecloud.com/api/v2/journey/deployments/10bd8ff4-b4df-425e-8d8c-5b302c039cf8/actionevent' }
  -H 'Content-Type: application/json' }
  --data-raw '{"sessionId":"4e521990-2e41-11ef-a8fa-55b338f632f1","actionId":"808e899a-51ac-3ac2-8c3b-4ad788623e82","actionState":"engaged"}

In response I get 204 No Content
I don't see a single engaged status in the ActionMap report.

PS. Yes, I have a hanging offer at this time. I am using the correct ActionId.

Please confirm that in the given scenario this should work.
