WhatsApp OTP, auto-read OTP for Android and iOS, and multi-channel routing across SMS, WhatsApp and voice — wired into a single auth API in private beta.

SMS and WhatsApp OTPs auto-fill into your Android and iOS app — no copy-paste, no app-switch. Built on the SMS Retriever API, iOS auto-fill, and WhatsApp's system OTP-hint format.
Multi-channel routing
Pick SMS, WhatsApp or voice automatically based on reachability and cost — with smart fallback the moment a channel fails or stalls.

We handle compliance
DLT registration, Meta Business verification and a template categorization workshop — done for you, not by you.
Ship login + campaigns

Marketing reach, utility deliverability.

Same platform that runs your authentication — utility-first template routing for both.
Utility-lane routing
Order updates, payment alerts, reminders — categorized into the utility template lane for higher delivery and lower cost.
Button click tracking
Meta gives no click data on WhatsApp template buttons — nobody else shows you this. We track every tap, per recipient, per campaign.
Template categorization workshop
Our team rewrites your template copy so Meta classifies it correctly the first time — fewer rejections, faster approvals.
Audience segmentation
Filter your customer list by behaviour, location, purchase history — send the right utility message to the right cohort.
Rate shaping & scheduling
Time-zone aware sends and adaptive throughput help keep the WABA healthy during bulk pushes — no flat-line throttling, fewer Quality Rating drops.
Block-resistant sending
Per-template pacing and Quality Rating monitoring help keep your sender healthy through high-volume sends — materially lower WABA-suspension and number-ban risk.

Questions, answered.
How does QuickAuth get higher delivery rates than other WhatsApp platforms in India?+
Most platforms push every business message through Meta's marketing template category — which carries higher cost, marketing-opt-in friction, and aggressive deliverability throttling. We use intelligent template categorization to route order updates, payment alerts, reminders and account notifications through the utility category whenever the content qualifies. Same Meta WhatsApp Cloud API, same policies — just routed into the lane the message actually belongs in. Result: higher delivery, fewer rejections, no marketing-opt-in friction.
Why don't you publish pricing?+
Real costs in India depend on your volume, channel mix, template categorization breakdown and fallback patterns. A static price list would either mislead you or quote you well above the deal we can actually offer. Aarav puts together a custom INR quote within 24 hours of your application.
What is DLT registration and do I have to do it myself?+
DLT (Distributed Ledger Technology) is the TRAI-mandated registry every Indian SMS sender, header and template has to be enrolled in. You don't have to handle it — our team takes care of DLT registration, sender ID and template approvals end-to-end, usually within 24 hours. Included with onboarding, no extra charge.
Does WhatsApp OTP need DLT registration in India?+
No. WhatsApp Business API messages run on Meta's platform, so they're outside TRAI's DLT scope — only SMS needs DLT. That makes WhatsApp OTP a fast way to start sending verifications without waiting for sender-ID approval. We still recommend SMS as a fallback channel for unreachable numbers.
Why deliver OTP over WhatsApp instead of SMS?+
WhatsApp OTP sends the verification code to the user’s WhatsApp inbox instead of SMS. On Android and iOS our SDK auto-reads it, so the user rarely types anything. In India WhatsApp typically lands faster and cheaper than SMS and sidesteps SMS-pumping fraud — with SMS kept as the automatic fallback for users without WhatsApp. Both run on the same Meta Cloud API and the same QuickAuth verify flow.
Does QuickAuth support auto-read OTP on Android and iOS?+
Yes. On Android we use the SMS Retriever API (app-hash appended to the OTP message; no SMS-read permission needed). On iOS we set UITextContentTypeOneTimeCode so the keyboard auto-suggests the code from the SMS. For WhatsApp OTPs we use the message-format hint that triggers Android's system OTP-autofill prompt. Reduces friction at the verification step — fewer drop-offs between code-sent and code-entered.
Can I use the same QuickAuth account for both authentication and bulk WhatsApp?+
Yes — that’s the point. QuickAuth runs auth (WhatsApp OTP, SMS OTP, multi-channel routing) and bulk WhatsApp business messaging (utility, marketing) on the same WABA, the same dashboard and the same template-categorization pipeline. Deliverability monitoring, template approvals and INR billing roll up across both — instead of stitching an OTP vendor, a marketing tool and a WhatsApp BSP into one stack.
How do you prevent SMS-pumping fraud?+
Four overlapping layers. (1) suspicious-prefix scoring — a maintained block-list of MNC and country prefixes commonly used for artificial traffic. (2) velocity and ratio heuristics — abnormal request-to-verify ratios on a number range get throttled. (3) per-IP and per-device quotas with graceful back-off. (4) optional device fingerprinting at the request step. The bulk of pumping attempts get blocked at the request step, before any OTP fires and any cost is incurred.
Is the QuickAuth SDK ready?+
Yes. The official SDKs — web (npm @quickauth/web), React Native, iOS (CocoaPods + SPM), Android (Maven Central in.quickauth:sdk) and Flutter (pub.dev) — are published and installable now. The platform itself is in production; API access rolls out to early customers as their volume justifies it, and many teams still run onboarding through the dashboard first.
Where is user data stored?+
Mumbai (ap-south-1). Phone numbers are hashed; OTPs are wiped 5 minutes after verification. SOC 2 Type II and aligned with the DPDP Act 2023.
One API for authentication and WhatsApp messaging.
Free tier included. No credit card required. Live in minutes.
