Multi-Tenant Isolation
Every variant and coupon is indexed with strict store_id tenant scoping, guaranteeing zero cross-store data leakage.
Sub-Order & OTP Handshake
Multi-vendor carts split into isolated vendor sub-orders with 6-digit cryptographic OTP confirmation upon customer handoff.
Dual-Provider Webhook Engine
Provider-specific signature verification for Razorpay (HMAC-SHA256 timingSafeEqual) and Stripe (constructEvent) with idempotency keys.
