Why was a reward taken back from my balance?

Sometimes an advertiser rejects a completion after it was paid — usually because the user cancelled a trial, refunded a purchase, or used a VPN to fake their country. When that happens the advertiser takes the money back, and the reward is taken back from your balance too.

We tell your server every time this happens, so you can take the coins back from that user as well. The notification carries the same transaction id as the original reward, with status reversed and a negative amount — so store each completion by transaction id and status together, or the reversal looks like a repeat and gets ignored. The postback guide shows the exact format.

Your conversions page shows every completion and every reversal.
