How WhatsApp Business API Integration Works

The API has no app and no interface of its own — it needs a platform on top. Here's the whole path from a phone number to a running WhatsApp operation.

GUIDED SETUP
Phone number connected
Meta Business account linked
Webhooks configuredby Flowcall
Test message delivered

Step 1 — Connect Your Number

Bring a phone number (new, or migrate your existing WhatsApp Business number) and a Meta Business account. The guided setup links them to Flowcall — no code, no webhook configuration on your side.

Step 2 — Get Verified

Business verification runs through Meta; green-tick (verified business) support is built in. Your display name, logo, and business profile get set up as part of onboarding.

Get Your Number Live on the API

Bring your number and thirty minutes. We'll walk the integration path end to end and show AI resolving a real query on WhatsApp before the call ends.

Three things: a phone number, a Meta Business account, and a platform on top of the API (it has no interface of its own). With Flowcall, the guided setup connects your number, business verification and green-tick support run through onboarding, and the implementation team wires your store, courier, and workflows — most teams go live in 2–3 weeks.

The app is a phone app for one person on one device. The WhatsApp Cloud API is for teams and automation: shared team inbox, AI agents, broadcast campaigns to opted-in segments, integrations with your store, and no device limits. If more than one person answers customers, you've outgrown the app.

Evaluate on what runs after the connection: does the provider just pass messages through, or resolve queries? Flowcall pairs the API integration with an AI Agent that resolves 80–90% of queries end to end, native UPI payments, a team inbox, and campaign tooling — and the same platform runs email, Instagram, and live chat, so WhatsApp isn't another silo.

Yes — existing WhatsApp Business numbers migrate to the API. Your customers keep messaging the number they already have; conversations continue with history intact on the platform side.

Yes. Your product catalog syncs from Shopify, WooCommerce, or any source, and products render as native carousels in the conversation — browsable, filterable by the AI, and orderable in the thread.
