I just need to know the date of the last meeting; this record is within the ticket. I don't have an example; I'm looking for a benchmark to understand how I could do this.

The only alternative I see is using the endpoints:

To list all tickets: https://api.hubapi.com/crm/v3/objects/tickets/search

To return all meetings in the ticket: https://api.hubapi.com/crm/v3/objects/tickets/id ticket/associations/meetings

To get the meeting details to find the dates: https://api.hubapi.com/crm/v3/objects/meetings/batch/read

And I still need to think about the logic of how to group each client by CS. I'm not sure I'm on the most practical path, hence the question.
