Use an outgoing postback to send a tracked event to another platform. First confirm that incoming events appear in Metricanic.

​
Configure the outgoing request

  1. Confirm that the visit contains the source’s click ID as External ID. See Traffic sources.
  2. Get the postback URL template from the receiving platform.
  3. Edit the campaign and select the event in 2. Events.
  4. Enable Outgoing postback and paste the template into Destination URL.
  5. Add the Metricanic macros required by the receiver.
  6. Save the campaign.
  7. Send a new test event for a tracked visit with a real external ID.
  8. Inspect the attempt in Postbacks, then check the receiving platform.
For a receiver that uses ad_click and amount, the URL could be:
If the visit’s external ID is ad-731 and the incoming payout is 24.50, the request sends ad_click=ad-731&amount=24.5. Replace the example endpoint and parameter names with the receiver’s actual template. Use source postback copies the selected traffic source’s URL into the event. If that source URL changes, update and save the events that should use it.

​
Know which click ID each system expects

Use {external_id} to return the traffic source’s original click ID. The incoming event uses Metricanic’s {click_id}. Check the receiver’s instructions. Its field named click_id may require {external_id}.

​
Send only the stages the receiver needs

For a lead campaign, you can record submissions and approvals in Metricanic but send only approvals. Enable Outgoing postback for the approval event. Count as conversion controls Metricanic’s conversion totals. Set Outgoing postback separately to control sending. If you use event rules, check the postback settings in the first matching rule.

​
Check the amount before relying on it

{payout} uses a valid incoming payout first. This can differ from recorded revenue. For example, incoming payout=24.50 with Fixed amount set to 20 records USD 20 revenue, but sends 24.5 through {payout}. If the receiver needs 20, enter that amount in its URL or change the payout sent by the originating system. Check the final URL in Postbacks. If a macro remains unresolved, check its spelling and the original visit’s values.

​
Send 50 percent of revenue in an outgoing postback

Use Revenue share (%) and {event_cost} when the amount is also a commission expense. This increases Cost and reduces Profit. Follow the commission example.

​
Distinguish delivery from attribution

A successful delivery does not confirm that the receiver attributed the conversion. Check its conversion count and amount. For Google Ads, follow the Google Ads guide.
