GET the Send History of an Email Campaign Activity

Use this method to return the send history of an email campaign activity. This method returns the send history as an array containing an object for each time you sent a specific email campaign activity to contacts.

Each send history object contains the email campaign activity send date, the number of contacts it was sent to, and the contact lists or segments used to send it. Each send history object also includes if the send attempt completed or encountered an error, and the reason why each error occurred. This method returns results in ascending order starting with the first send attempt.

If the email campaign activity has not been sent to contacts, this method returns a 200 response and an empty array.
