Prosper202 gives every click its own id. Awin carries that id in its clickref field and sends it back when a conversion happens, so the sale is credited to the click, its traffic source and its cost.
1. Put the click id on your offer URL
In Prosper202's campaign setup, add this to the Awin link you were given, keeping your affiliate id and the other parameters as they are:
clickref=[[subid]]awc is Awin’s own click identifier, not yours. Put ClickRefs before the ued destination URL.
Spare fields for your own tokens such as [[c1]]: clickref2–clickref6.
2. Send conversions back with a postback
Enter Prosper202's global postback URL in Awin (Toolbox › Transaction Notifications):
https://your-tracking-domain.com/tracking202/static/gpb.php?subid=!!!clickRef!!!&amount=!!!commission!!!- Use your own tracking domain. Step 9 of the setup (Conversion Tracking) gives you the URL with it filled in.
subid=!!!clickRef!!!is Awin's token for theclickreffield, so it sends back the click id from step 1. If you put[[subid]]in a different field, use that field's token.amount=!!!commission!!!records the payout Awin reports. Leave it out to keep the payout you set on the campaign.
3. Test it before you send traffic
Click your own tracking link once, then check that the click arrived and that a test conversion finds it. On an install with Prosper202 ClickServer Pro, p202 conversion simulate runs the whole loop for you. If a conversion doesn't show up, see Conversions Not Showing Up.
Things that trip people up
- Transaction Notifications may be missing from your Toolbox menu. Awin asks you to raise a support ticket to get access. Source
- Awin sends notifications only to ports 80 and 443, so your tracking domain can't use a custom port. Source
- Click references can't contain # + " ; & | or '. Prosper202's click id is a plain number, so leave clickref holding only [[subid]]. Source
