Hi Nahla,
There are for sure APIs for that as everything in the GUI runs in the back through APIs.
however they might not be documented/Supported but it is still fun for me to try every now and then.
I checked quickly I founds the below API nodes they might be helpful for you :
orgs/201/incidents/{inc}/action_invocations
Sample query: /rest/orgs/201/incidents/2253/action_invocations
Query String Parameters
want_children: true
status: 0
status: 1
status: 2
status: 3
Result should be usually with status 0 if completed however the time out comes with status 3.
Let me know If you where able to use it or if you need more info.
Regards,
