Some Offers track more than one conversion event — for example, an app campaign that tracks an Install, a Registration, and a Sale within the same Offer. Each event can have its own classification, payout, and visibility settings.
This article walks through a complete example of how to set up a multi-event Offer in Aftrad.
Overview
In this example, the Offer has three events:
Install — tracked as a KPI (informational, no payout)
Registration — tracked as Payable ($2 per conversion)
Sale — tracked as Payable ($10 per conversion)
Each event is configured as a separate payout rule in General > Payouts & Events. The Install is set as the Default payout rule, and Registration and Sale are set as Custom payout rules.
💡 Tip: The Default payout rule acts as a catch-all — any event that doesn't match a Custom rule will be attributed as the default event type. In multi-event Offers, it's common to use the Default rule for the first event in the funnel (e.g., Install) and Custom rules for subsequent events.
Step 1 — Configure the Default payout rule (Install)
The Install event is configured as the Default payout rule with the following key settings:
Classification — KPI — this event is tracked for reporting purposes only and does not generate a payout for the Affiliate.
Event parameter — leave empty or set to None, since any postback without an
event_parametervalue will match the Default rule.
For a full description of all available fields, see Offer payout rules.
Step 2 — Configure the first Custom payout rule (Registration)
The Registration event is configured as a Custom payout rule with the following key settings:
Event parameter — set to List, with the value
registration. This means Aftrad will apply this rule only when the Advertiser sendsevent_parameter=registrationin their postback.Classification — Payable — this event generates a payout for the Affiliate.
Step 3 — Configure the second Custom payout rule (Sale)
The Sale event is configured as a Custom payout rule with the following key settings:
Event parameter — set to List, with the value
sale. Aftrad will apply this rule only when the Advertiser sendsevent_parameter=salein their postback.Classification — Payable — this event generates a payout for the Affiliate.
Step 4 — Share the Postback URL with the Advertiser
Share the Advertiser Postback URL with the Advertiser and agree on the event_parameter value they will send for each event. These values must match exactly what you configured in the payout rules above.
For this example, the Postback URL structure is:
https://yourpostbackurl.com/api/v1/events?click_id={click_id}&event_parameter={event_type}&payout={payout}And the expected postbacks per event are:
Install — event_parameter is empty or not sent:
https://yourpostbackurl.com/api/v1/events?click_id=XXXXXXXX
Registration — event_parameter=registration:
https://yourpostbackurl.com/api/v1/events?click_id=XXXXXXXX&event_parameter=registration
Sale — event_parameter=sale:
https://yourpostbackurl.com/api/v1/events?click_id=XXXXXXXX&event_parameter=sale&payout=10
Step 5 — Verify events in Advertiser Events
Once the Advertiser starts sending postbacks, go to Performance Hub > Advertiser Events and filter by Click event ID to verify that each event is being received and correctly attributed.
