Purchase referrals connect a participant’s unique referral link to your Shopify storefront.

1. Open the Purchase Sweepstakes post-entry or install settings.
2. Enable referral tracking and configure the entry award.
3. Confirm the destination storefront page.
4. Save and publish the required Shopify app embed.

Revup carries referral context through normal cart and accelerated product-checkout paths using the available Shopify mechanisms. A qualifying purchaser is associated with one referrer under the promotion rules; later competing links should not silently replace a confirmed attribution.

Test with two separate customer identities from referral link through paid order. Confirm the referred purchaser qualifies, the referrer receives the correct entry award, and a refund later reconciles the award when required.

Explain the referral requirement and award in the official rules. A click alone should not be described as a completed referral when a qualifying purchase is required.
