Postback secret


To prevent fake conversions from sophisticated bots or from spy, you can protect your post back url by enable "Postback Secret".

Once enabled, you need to put a few characters as a secret, or click the button to let system generate random secret for you.

Then add the &secret=YOUR-SECRET to your post back url. Post back request with wrong secret will be rejected. So don't share this secret with anyone once you save the affiliate network details.


The Postback Secret is set on affiliate network level, which means if set a secret for an affiliate network, won't affect postback for other affiliate networks.
