Is it not possible to send conversion payouts back to Decisive through
I got the following error message from
postback URL used: http://win.crwd.io/convert/{externalid}{payout}
Do I need a parameter between {externalid} and {payout}?
Signed,
Confused
It's not possible. If you review Decisive's help documentation you'd see that they expect a bidhash. Nothing else.
There's no point trying to tell a programmed system about something it isn't programmed to interpret.
In your specific example, even for me - a human - I'm left wondering "WTF is the payout?" Is it $750.68? $50.68? $0.68?
Decisive gives you a CPA. You know offer payout, so calculating profitability is simple. (Payout - CPA) * (number of conversions).
