Native WhatsApp share

Double-sided reward
Inviter gets ₹100/$10/€10 on first qualifying purchase. New customer gets the same on first order.
AI fraud detection
Same-device, same-IP, same-payment-method blocked. AI flags suspicious sign-up patterns.
Reward confirmation template
Utility-category send confirms inviter reward unlock with Shopify discount-code injection.
People also ask
Q.Is a referral invite Marketing or Utility?
The invite send IS customer-initiated (they tap Share) — fully free. Only the inviter's reward confirmation is a Utility template.
Q.How do I structure the reward?
Double-sided works best: ₹100 / $10 / €10 to the inviter on first qualifying purchase, plus the same value to the new customer's first order.
Q.How do I prevent self-referral fraud?
LandinChat blocks same-device, same-IP, and same-payment-method referrals. AI flags suspicious patterns (rapid sign-ups, fake numbers).
Q.What viral coefficient should I expect?
Healthy programs hit K=0.3–0.7 (each customer brings 0.3–0.7 new customers). K=1.0+ is true viral growth.
Q.Can I gate rewards on minimum order value?
Yes — set a minimum AOV threshold for reward unlock, plus optional product-category gates.
Q.How do I track referral attribution?
Unique referral code per inviter + Shopify discount-tag attribution. Full dashboard with K-factor, payout tracking and top-referrer leaderboard.
Why WhatsApp referrals beat email and link-share
Email referral programs hover at K=0.05–0.1 — virtually no viral lift. WhatsApp share is one tap, lands in a personal thread, and converts at 3–5x because it's a real friend-to-friend recommendation.
Because the share itself is customer-initiated, it's free — you only pay for the inviter's reward confirmation (Utility template) and the new customer's welcome (Marketing template).
LandinChat blocks self-referral fraud (same-device/IP/payment-method) and runs an AI ranker on sign-up patterns. Healthy programs hit K=0.3–0.7 and cut CAC by 60–80%.
