Voluum allows you to send a separate postback URL for each conversion event.
Setup
Step 1. Create custom conversion events
Go to Settings → Custom conversions.
Create a custom conversion event for each conversion type you want to track.
Step 2. Configure postback URLs
You can configure postbacks either in the Traffic Source or directly in a Campaign.
Traffic Source
Enable Traffic source postback URL per event type.
Click Add event for each conversion type.
Select the corresponding event from the drop-down list.
Enter the RollerAds postback URL with the appropriate goal value.
Campaign
Open your campaign.
Expand Conversion reporting to traffic source.
Select Unique for this campaign.
Click Add event for each conversion type.
Enter the corresponding RollerAds postback URLs.
Important! Campaign-level postback settings override the traffic source configuration.
