Hi @... you'll want to use submitter role for your query. The Support API docs explains the difference as follows.

The submitter is the user who created a ticket. By default, the requester of a ticket is the submitter. For example, if your customer emails your support address, this creates a ticket with the customer as both the requester and submitter. The requester will also appear as the author of the ticket's first comment.

However, a support agent can also create a ticket on behalf of a customer. If an agent creates a ticket through the web interface, the agent is set as the submitter.
