With the Zonka Feedback + Zendesk integration, you were able to send surveys when the ticket status is updated. And now based on customer requests and feedback, and to make this more flexible and scalable, we have added the ability to create multiple triggers based on any Zendesk ticket fields to trigger Email or SMS Surveys to your customers. 

This covers you for all events when you want to measure customer satisfaction and agent feedback
