Thanks for your prompt response. Let me put up my question in a little more detail:
So basically I have created a HubSpot App that sends data to a 3rd party app on certain events on a user action. For eg. whenever a user updates a contact, we send the updated record to 3rd party platform. So far this is all doable. What I want to now do is also send the details of the person who is currently logged in ( the person who actually performed the action).
Do you think this is possible to fetch the Currently logged in user via the API on any trigger?
