How to get emailSend activities for all contacts in one API call?
I know how to get the EmailSendActivity for each contact with the provided API.
However, there are a huge number of target contacts that I want to acquire,
and I would like to avoid API calls for that number.
So I'm looking for a way to get the EmailSendActivities for all contacts in one API call.
Is it possible to use CustomObject or somehow achieve it in some other way?
I look forward to your skills.
Thank you.
