The Heureka | Ověřeno zákazníky app automatically exports order data to your account at Heureka. Heureka then sends out to the email address in the order a satisfaction questionnaire for the customer to fill out.
​
After obtaining a specific number of positive reviews from customers in the satisfaction surveys, Heureka awards an Ověřeno zákazníky (Verified By Customers) certificate that can be added to the store frontend.
