I am currently using Constant Contact API v2
If i have a list id and want to see which email campaigns got sent to a certain list currently i have to...and please correct me if i am wrong....
Please let me know if there is a simpler way of doing this?
Sorry if this seems overcomplicated, but I believe you're doing this in the most efficient manner possible. We actually haven't gotten many related requests, although we do get requests to see other types of list history data. Our data structure currently doesn't store much history for lists particularly and that's why you have to go through another avenue, like getting the email campaigns first like you are. Storing more list history would be a rather large feature and/or infrastructure change for us, but I will pass on your feedback!
