How do I record a sale that happens offline?

Mark the action “Only I record this, in Affily” — a house sale, a signed contract. Your site and tag can then never report it, so nobody can fake one.

When it happens, find the tracked action it came from (the viewing) in your activity — search by its id — and choose “Record sale”. It goes to the creator who brought that viewing, however long ago it was, and pays what that creator’s terms say. After the program has ended it is still recorded against them, but paid only if the program keeps paying after the end. The screen shows the amount before you confirm.

Recorded one by mistake? Undo it while it is still unsettled, and record it again.
