1. Enable the Marketing Hub module and set Allow Refer a Friend = Yes, then set Digital Amount to Referring Customer (what the referrer gets) and Digital Amount to Referred Customer (what the friend gets).
2. Each customer gets a personal link https://yoursite/register?ru=THEIR-ID, shown in the Invite a friend popup (profile banner, and optionally the site footer). They can copy it, email it from the popup, or share it on Facebook, X, LinkedIn or WhatsApp.
3. When someone opens that link, Sprwt remembers the referrer for the session; if they register, the new account is tied to the referrer.
4. When the new customer completes their first paid order, both wallets are credited: the referrer receives "Referral from #ID Name" and the friend receives "Referral #ID". Both also get the referral emails ("order_referral_referrer" / "order_referral_referee").

Nothing is paid at registration — only at the friend's first checkout.
