To enable support for s2Member, go to Affiliates → Settings → Integrations and check the box that says s2Member:

Once enabled, AffiliateWP will automatically generate referral records when a customer successfully registers for your site after clicking on a referral link.

In Affiliates → Referrals the Reference column refers to the transaction ID from your merchant processor (Stripe, PayPal, Authorize.net, etc.) for the payment recorded in s2Member.

Important notes:

  • Referrals will only be credited on the initial signup payment, and will not be created when subscription payments are recorded.
  • In order for referral tracking to work properly, your IPN / webhooks must be configured for s2Member. Consult the s2Member documentation for further information if you experience issues with referrals not being created properly.
