When a user completes a survey we send a callback. For this purpose, you can enter a URL with the desired parameters.
All optional tags that are specified are automatically attached to the callback.
At the end of each callback, we append a "&hash=[HASH]".
This hash consists of a HEX encoded SHA1 HMAC.
The whole URL is hashed with the secret key of the App.
