For any given lead I know I can get it's Activity through the Get Lead Activities endpoint. My problem is I want to get the first ever activity recorded for that lead all the way to the last. Is there a way to do this? If I try I date set way in the past (epoch) I get the following response:
Would I have to go through each pageToken till I get data? Is there a way to get the date of the first activity record for a lead?
