Clickbank Instant Notification

  • Clickbank uses a different format for the Postback URL and passes encrypted details about conversions.

  • CPV Lab Pro offers a dedicated Clickbank Postback URL that will decrypt data and mark conversions in the database.

    • In order to decrypt data you need to define the same Secret Key both in Clickbank and in CPV Lab Pro.
    • The Secret Key can have a maximum of 16 uppercase letters and digits.
  • Starting with CPV Lab Pro 5.0 you have support for version 7.0 of the Clickbank Instant Notification. This version 7.0 allows the code to execute on PHP 7.2 and above because it doesn’t use the mcrypt extension like the old 6.0 version.

You’ll setup your campaign as you normally would but when entering your Clickbank offers you need to allow the steps below:

1. Select Clickbank as the Offer Source.

  • Clickbank must be selected as the offer Source or the SubIDs will not work correctly.
  • CPV Lab Pro generally uses spacing characters _ in SubIDs, but these types of characters are not allowed in Clickbank Tracking IDs.
    • So when Clickbank (exactly as show) is selected then CPV Lab Pro will automatically change the spacing character in the SubIDs to “z” in order to pass correctly to Clickbank.

2. Entering Clickbank Offer URLs

  • When entering Clickbank Offer URLs, be sure to include the Tracking ID Parameter they support to the end of the offer url as: ?tid=

3. Setup Clickbank Instant Notifications for Conversion Tracking

  • In your Clickbank Account

    • go to the My Site page under Vendor Settings menu, then click Edit in the Advanced Tools section

    Advanced tools

    • enter the secret key that you set above
    • set the Instant Notification URL to: http://cpvlabpro-domain/adclick-cb70.php
      • make sure you replace cpvlabpro-domain with your actual domain name
    • Select Version 7.0 and then Click TEST IPN.

    Test IPN

  • If the URL is correct, you should see a Verified message appearing next to the URL

    Verify IPN

  • Clickbank will automatically send the following parameters to the URL:

    • ctid – the Clickbank transaction ID which must be setup to be the CPV Lab Pro subID
    • caccountamount – the conversion revenue (in cents)
  • CPV Lab Pro will read these 2 values and mark the correct conversion in the database, as well as store the actual revenue, then execute any additional server-to-server pixels setup for that campaign.

  • Because the Clickbank performs a POST request, any 3rd party pixels entered as image, iframe or script won’t execute

    • so in this case only server-to-server 3rd party pixels will fire (those are entered as simple URLs in the campaign setup page).
  • The Clickbank pixel allows multiple conversions from the same subID.

    • If the pixel fires more than once for the same subID, CPV Lab Pro will sum the revenues that were sent from Clickbank.
  • Go to the Configuration Editor page (under Settings) and edit the Clickbank Secret Key and Clickbank Sale Status variables;

    • Enter the same Secret Key that you have entered in your Clickbank account previously:
