If you want to set the postback you need to go to the "Offer / Postback". There you can see all your postback and their settings. The postback settings really depend on a few factors. For which offer/offers do you want to fire the postback, on the offer event. You can set multiple postbacks.
Offer: You can select one or more offers.
Event: On which events should the postback react and fire. If you will leave the field empty, it will fire for every event occurring.
Status: Should be set for "Approved" or "By Creating"
