Starting from July 1st, 2019:
requesterattribute of the Ticket object (containing a User object) will be removed and replaced by the
customerattribute (containing a Customer object). This will affect Ticket objects returned by our API and payloads of our webhooks. The
customerattribute of the Ticket object is already available so you can update your applications to use this new attribute starting today.
If you have any further questions about these changes, please don’t hesitate to contact our support.
