How to get ticket creator on Freshservice?

Hi everyone :grinning_face_with_smiling_eyes:!

At freshservice we can create a ticket for another requester, as shown in the image (the agent Felipi created the ticket for the requester Pablo).

I would like to get this information via onTicketCreate event or API.

Is there a way to accomplish this?

Regards,
