This tutorial will explain the basic reasons why a postback doesn't work and how to fix them.
Mistake 1: not passing the unique click ID to the Everflow Platform in the tracking link.
How it works
In order for a conversion to post to an external platform there needs to be a unique click ID being sent from that external platform to Everflow.
For every click generated using an Everflow tracking link(example: http://everflow-demo.servtrk.com/21KL6/D42TR/) there needs to be a spot to pass the click ID generated on the Affiliate's third party platform.
Make sure every tracking link you implement has a spot to pass the click ID macro.
Example of a GOOD tracking link:http://everflow-demo.servtrk.com/21KL6/D42TR/?sub1=[click_id]
Mistake 2: Not passing that click ID back to the affiliate's third party platform.
Add a spot to the postback url to pass the data being collected in the tracking link.
Example of a GOOD Affiliate Postback:
As you can see the sub1 spot is collecting the click ID in the tracking link, then it is used to pass back the same click ID in the postback when a conversion is generated.
