We have integrated Hubspot single send api in our application to send transactional emails.
Recently found (from April 6th 2017) that single send api is returning extra attribute ‘eventId’ for sendResult=‘SENT’ response. Earlier to April 6th ‘eventId’ attribute was not there in response. The new attribute is not recognized in our application and its breaking.
Please revert the hubspot single send api response so that eventId attribute is not sent when sendResult=‘SENT’
