WhatsApp Business API development

Conversations that carry the business.

The hard parts are never the messages. They are template approval, opt in records, the 24 hour session window, webhook reliability and per conversation pricing. We design for those first and the interface second.

WhatsApp and Meta APIs

We build on the WhatsApp Business Platform Cloud API: account onboarding, template approval, webhook services and the CRM layer on top. It is the same ground the hosted WhatsApp platforms cover, except the account and the data stay yours, and it is the work Indian businesses ask us for most.

What we build

  • WABA setup and business verification support
  • Message template design and approval
  • Cloud API webhook services with delivery and read receipts
  • Campaign and broadcast tooling with opt in capture and an audit trail
  • A shared team inbox with assignment, tags, notes and bot to human handover
  • Catalogue and order flows

What you get at handover

A verified business account in your name, templates approved against your brand, and a service that behaves under Meta’s rate limits and pricing changes.

Engagement shape

Discovery first, because business verification is the long pole and not the code. Then a fixed scope build, then a retainer while message volume settles.

Stated plainly

We are not a Meta Business Partner and not a Solution Partner. We build as a developer on the Cloud API, which means your business account, your billing and your message data stay yours. We cannot resell API access, message credits or green tick verification, and nobody can guarantee template approval, because Meta decides it.

Proof

What we have built on it.

Ami’s Craft routes live orders into WhatsApp with a structured order reference, so payment and fulfilment happen inside the chat. Our reminder assistant is at MVP and is migrating from an unofficial library to the Cloud API, which is the same migration every business still on one will have to make.

We get close to 1,100 enquiries a month on WhatsApp and most of them were going unanswered until someone checked the phone at night. Kyron moved us onto the Cloud API, got our templates approved, and routed every enquiry to a named person with a follow up timer. Average first reply is now under twelve minutes. It also came in below the yearly cost of the readymade CRM we were evaluating.

However we work together

  • You own the IP. It transfers on final payment and it is written into the statement of work, not only the master agreement.
  • We sign your NDA, or ours, before the first technical call.
  • Repos, cloud projects and store accounts are created in your name on day one, and our access is revoked at project close.
WhatsApp and Meta APIs, in practice

What clients ask about this one.

No, and we will not imply otherwise. We build as a developer on the WhatsApp Cloud API. Your WhatsApp Business Account, your Meta billing and your message data stay in your name.

No. Meta decides template approval, green tick verification and whether a number gets restricted. What we can do is design templates that follow the current policy, submit them, and handle the rejections.

A hosted platform is faster to start and charges per month, per user or per conversation on top of Meta’s own pricing. An owned build costs more up front and keeps the number, the data and the integration inside your business. We will say plainly when a hosted platform is the better answer for you.

A Meta Business account with two factor authentication, a verified business through Meta’s document review, and a display name that passes their naming policy. We prepare the submission with you. The timeline is Meta’s, not ours.
