Bengaluru brands ship across India, start-ups build WhatsApp into their products, and clinics and ed-tech firms need reminders that arrive. We set up the official WhatsApp Business API for them as a verified Meta Tech Provider, entirely online.
AvanceZone Technology is a verified Meta Tech Provider for the WhatsApp Business Platform, based in Sulur, Coimbatore, with no office in Bengaluru. Onboarding is fully online, as it is with any WhatsApp API provider: business verification, number connection, templates and webhooks are all done remotely. Meta bills each delivered message. Indicative India rates since 1 October 2026 are ₹0.8631 per marketing message and ₹0.115 per utility, authentication or service message, with 1,000 service messages free per business number each month. Add 18% GST and our platform fee, which we quote after a short call.
For a brand shipping cash-on-delivery orders across India, the most useful message is often the cheapest: a utility template asking the customer to confirm before the parcel is packed. A cancellation on WhatsApp costs about ₹0.115 in Meta charges; a parcel the courier brings back costs far more.
What the customer sees
Hi Ananya, please confirm your cash-on-delivery order BLR-48213: 2 items, ₹1,348, delivering to Koramangala on Thursday.

Cart reminders are a different category. Meta's guidelines list "you left items in your cart" as marketing even if the customer asked for reminders, so each one costs about ₹0.8631. Send one, to customers who opted in, and stop.
Catalogues and in-chat payments let customers browse and pay inside the chat; drips and retargeting are on our WhatsApp marketing page.
If WhatsApp is a feature inside your product, the dashboard is secondary. The usual order of work:
One POST to /api/v2/whatsapp/send sends an approved template to your own phone.
Approved templates can go from our shared platform number while your own number is verified. Free-form replies need your own number.
Inbound messages and delivery statuses reach your HTTPS endpoint, signed with HMAC-SHA256 so you can reject forgeries.
Read approved templates by API, so code never sends an unapproved name or language.
Move sends to your own number. SMS fallback for OTPs and failed sends uses the same API key.
Working code, error codes and the same send against Meta's Cloud API are in our guide to sending WhatsApp messages from PHP.
Meta's test for utility: non-promotional, and specific to the person's order, account or service. Reminders about a booked appointment or a fee already owed pass. Anything that sells, upsells or chases a renewal is marketing, at about 7.5 times the price.
| Message | Category | Why |
|---|---|---|
| Your physiotherapy session is on {{1}} at {{2}}. Reply to reschedule. | Utility | About a booking the patient made |
| Term 2 fee of ₹{{1}} for {{2}} is due on {{3}}. | Utility | A payment owed on an existing account, with no offer |
| Renew before {{1}} and get 20% off next term. | Marketing | Tries to secure a renewal with an offer |
| Book your annual health check this month. | Marketing | Promotes a service the patient has not booked |

When someone taps a click-to-WhatsApp ad and sends the pre-filled message, Meta attaches a referral to that first message: the ad's ID, headline and source URL, and a click ID (ctwa_clid).
Our platform records the first referral on the conversation, so each lead stays tied to the ad that brought it, even after later campaigns. That lets you compare ads by the conversations they start, not just by clicks.
The free entry point window
Meta's pricing page, checked in November 2026: if the customer messages you from a click-to-WhatsApp ad on the WhatsApp Android or iOS app and you reply within the customer service window, your reply opens a free entry point window that may stay open for up to 7 days. While it is open, Meta does not charge for marketing, utility, authentication or service messages.
Two limits: chats started from WhatsApp on desktop or web do not qualify, and the ad spend is billed by Meta separately.

In the 2011 census, Kannada was the mother tongue of 42.1% of Bengaluru's people, followed by Tamil (16.34%), Telugu (13.73%), Urdu (13.00%) and Hindi (4.64%). Brands here also ship nationwide, which is where Hindi templates earn their place.
| Template | Code | Text from | Status |

order_update | hi | Your Hindi copy | Approved |
An illustration. Until the Kannada entry is approved, a send with "language": "kn" fails, so your code should send the English one. Billing is by category, not language.

Meta has split the old WhatsApp Business Account in two: a WhatsApp account holding your number, profile and catalogue, always owned by you, and a Messaging account per provider holding templates and billing. The change arrived on 23 September 2026 and, Meta says, reached all businesses by mid-October.
Meta controls every step above and says its documentation is subject to change. We check the current process on the day we start and never promise dates for anything Meta reviews. Chat history held in your old provider's inbox stays in their system unless they export it.

| Line | Messages billed | Indicative rate | Amount |

| Marketing Two campaigns to 6,000 opted-in customers | 12,000 | ₹0.8631 | ₹10,357.20 |
| Utility Order, COD and shipping updates | 8,000 | ₹0.115 | ₹920.00 |

Marketing is 89% of the Meta charges here, so the size of the campaign list matters most. Messages inside a free entry point window from a click-to-WhatsApp ad would cost nothing, and utility rates fall in volume tiers. Meta revises its rates; we confirm the live rate card before launch. Without a payment method on file, Meta stops delivering service messages once the free 1,000 are used.
