Follow these directions to set up recurring commissions from Chargify for your Referral (or Affiliate) program.

NOTE: You must also have the ambassador javascript snippet on your payment success page, to record the initial commission.

1. Go to Chargify -> Settings -> Webhooks

• Enable webhooks
• Specify URL to your webhook handler
• Check "Renewal Success" in "Webhooks subscriptions"
• Save webhooks settings

2. Add ambassador_chargify.php file to your libraries folder.

3. Set values for $username, $api_key and $campaign_uid variables, and add additional variables (optional).

You can find them here:

• https://getambassador.com/c/general
• https://getambassador.com/c/campaigns

Additional Variable Information located in API docs:

• https://getAmbassador.com/api

4. In your function which handles webhook data add this code:

4.1 PHP

NOTE: You need to specify path to your library folder

require_once(PATH_TO_LIBRARY_FOLDER.'/ambassador_chargify.php');
$ambassador_chargify = new Ambassador_chargify();
$ambassador_chargify->renewal();

4.2 PHP + CodeIgniter

$this->load->library('ambassador_chargify');
$this->ambassador_chargify->renewal();

5. Run your webhook URL in a browser to check if there are any errors displayed. If you see blank page, it is ok.
