If you're a Decision API client (firing impression and click urls server-to-server) the pixel method won't work because Kevel isn't dropping a cookie at time of ad request. Instead, you'll need to make a server-to-server call when the conversion event is triggered.
Add the macro of
?conv=%conversionid%to the Click URL when Setting up a Creative , such as,
http://www.nike.com/?conv=%conversionid%. This will generate a GUID like
In the Decision API Response, you'll see the GUID in the
clickURLfield. Save this GUID and keep it tied to the user. Options include:
a. Storing it on a cookie
b. Tying it to a persistent ID and storing in a database
c. Persisting the
conv=GUIDin the URL
Once the user has made a conversion, you need to GET the below endpoint and append the GUID from the original click. As the GUID is tied to a specific ad, when you ping the endpoint, Kevel will register a conversion for that ad and add it to reporting.
The endpoint is:
Note that the conversion macro will not unfurl until after the click is called. Therefore you will not be able to get the conversionId from the response itself - only from the clickURL.
Server-to-server conversion tracking works the same as above. However, it does require the Advertiser having to do steps #2 and #3 in their system, so it will not be a turnkey set-up for them.
Some additional parameters you could append to the endpoint are:
override: replaces the revenue value of the conversion (f.e. appending
?override=1.23would set the revenue to $1.23)
additional: adds the specified value to the original revenue value of the conversion (f.e. appending
?additional=1.23would add $1.23 to the original revenue for the conversion)
