WhatsApp Business API in Chennai, Tamil Nadu

What it actually costs in Chennai

Since 1 July 2025, Meta bills the WhatsApp Business API per delivered message, priced by category — marketing, utility or authentication — not per 24-hour conversation. The old per-conversation model is gone; the 24-hour window is now a free customer-service window, not a billing unit, so replies to an inbound customer message within that window carry no per-message charge — free today, chargeable from 1 October 2026. InfiQ applies its own transparent platform pricing on top of Meta's live India rate card, quoted in ₹ and ex-GST, with GST invoiced to your Tamil Nadu GSTIN. Our plans (starting around ₹999 and ₹2,999 per month, plus Enterprise) cover the platform, agent seats, automation and support; message volume is billed on Meta's per-category rates. You get an itemised view of what's platform fee versus message spend, so a Chennai finance team can reconcile every rupee.

• Marketing messages: promotions, offers, re-engagement — the highest-rate category
• Utility messages: order, payment and account updates tied to a transaction
• Authentication messages: OTPs and login verification
• Service replies inside the 24-hour window: no per-message charge (free today, chargeable from 1 October 2026)

Onboarding a Chennai business, step by step

Getting live on the official API is a defined sequence, and InfiQ handles the parts that usually trip businesses up. First, we verify your business in Meta Business Manager — for most GST-registered Chennai companies this maps cleanly to existing documents. Next, you connect your phone number through Meta's Embedded Signup, and critically you retain ownership of your BSUID (Business-Scoped User ID) and WhatsApp Business Account throughout — InfiQ never holds your number hostage. Then we help you draft and submit message templates for approval in Tamil, English and Hindi, structured to pass Meta's review the first time. Once templates clear, you go live, typically within 2 hours including business verification. We also confirm your green-tick (Official Business Account) eligibility as part of setup.

• Business verification in Meta Business Manager using your existing GST and company records
• Number connection via Embedded Signup with full BSUID and WABA ownership retained by you
• Template drafting and approval in Tamil, English and Hindi
• Go-live and green-tick eligibility check, usually within 2 hours

Support and messaging in your language

A channel only works if your customers and your team both feel at home in it. InfiQ supports messaging in Tamil, English and Hindi, so a customer in Chennai can read an order update in Tamil while your back office works in English, and templates can be maintained in more than one language for the same use case. Support runs on India hours, aligned to how Chennai businesses actually operate, so you are not waiting on a foreign time zone when a template gets stuck in review or a campaign needs to go out before a Pongal or Diwali push. Because InfiQ is WhatsApp-first, everything here is focused on getting your WhatsApp channel right rather than spreading you thin across half-built channels.

Ownership, compliance and the 2026 usernames change

Serious Chennai businesses care about who owns the asset. With InfiQ you keep your WhatsApp Business Account and your BSUID, so if you ever change providers your number, history and green tick move with you. On compliance, the API's template and opt-in rules protect your sender quality — we help you collect valid opt-ins and keep your quality rating high so your daily messaging limits scale up rather than getting throttled. Looking ahead, WhatsApp is rolling out usernames in 2026, where customers can reach a business without exposing a phone number, tied to the BSUID identifier — building on the official API now means you are positioned for that change rather than scrambling later.
