Auth + WhatsApp messaging, built for India. One API. | QuickAuth

Hey Product Hunt 👋 I'm Hardik, founder of CodeLamda. Today we're launching QuickAuth — and I want to tell you the story behind it, not just the feature list. The moment we knew we had to build this: Last year we were helping an Indian D2C brand ship their checkout. They were on Twilio for SMS OTP (₹0.25/SMS, billed in USD), Wati for WhatsApp order updates, and had just lost their WABA for the second time because a "thank you for shopping" template got flagged as marketing. Their dev team was firefighting across three dashboards while the founder was losing sleep over a suspended WhatsApp number that 40% of his customers depended on. That's not a product problem. That's a stack problem — and every Indian team building on phone numbers is living it. Here's what we did differently: → Same WABA powers auth AND bulk messaging. Your "Login with WhatsApp" button and your "order shipped" campaign share one number, one dashboard, one INR invoice. No vendor sprawl. → Utility-lane routing for everything that qualifies. Order updates, payment receipts, delivery alerts — auto-categorized into Meta's utility template lane. Higher delivery, lower cost, no opt-in friction. ~98% delivery on utility templates in production. → WABA stays healthy. Template categorization workshops with our team before you ship a campaign. Adaptive rate-shaping during high-volume sends. Sender-quality monitoring with alerts. Zero account suspensions across 500k+ messages so far. → Login with WhatsApp drops OTP friction. One-tap sign-in, signed callback to your app, no 6-digit code typed on a tiny keyboard. +34% signup conversion on Indian numbers in our pilot. → DLT + Meta verification handled. You don't fill a single TRAI form. We do DLT registration, sender ID approval and Meta Business verification within 24 hours. Included with onboarding. → SMS-pumping protection — suspicious-prefix scoring, velocity heuristics, per-IP quotas. Pumping gets blocked at the request step, before any OTP fires and any rupee is burned. The boring details that matter: Mumbai data residency (ap-south-1) DPDP Act 2023 + SOC 2 Type II Phone numbers hashed, OTPs wiped 5 min after verification API mirrors Twilio Verify-style signatures — most migrations take an afternoon Where we are: Private beta. 800+ teams on early-access. End-to-end production-ready from the dashboard today; API access opens up as volume justifies. SDKs for Node, Python, PHP and Flutter shipping to early customers through late 2026. Free tier on both products. INR billing throughout — no FX surprises. The honest ask: If you've ever fought a WABA suspension, watched SMS-pumping bills climb, or spent two weeks chasing a DLT template approval — I'd love your feedback. Roast the pricing, the API, the positioning. All of it. I'm here all day. 📧 contact@quickauth.in 💬 +91 95749 80048 🇮🇳 Made in Surat, Gujarat
