How it connects

Three WhatsApp engines. Pick the one that suits you today.

Most platforms give you Meta's official API and nothing else, so you wait on approval before you can send a word. Flash Chat gives you three engines for WhatsApp — and SMS besides — and you can run them together on one account.

FlashQR

The simplest way to get a number working. Scan a QR code with the phone you already use and start sending. Nothing to install, nothing to run.

Live in: Minutes
Does: Text, media, delivery reports
Trade-off: The essentials only

OpenWA

Also linked by QR, but driving a full WhatsApp client. Groups, chat history, editing a message you already sent — the things a business API simply cannot do.

Live in: Once the engine is running
Does: 47 operations
Trade-off: You host the engine

Cloud API

Meta's own channel. Approved templates, tappable buttons, and the only engine that keeps sending while your phone is switched off.

Live in: Once Meta verifies you
Does: Templates, buttons, ad tracking
Trade-off: Needs a Business Account

And SMS, from your own SIM

Not a WhatsApp engine, so it sits outside the comparison below. Install the Android app on a handset with your SIM and it reaches the people none of the three above can — the ones who are not on WhatsApp. Carrier rates apply, and the phone stays online.

You are not choosing once. Run all three on one account — and SMS alongside them — and the same inbox, contacts and automations sit behind every one.

Features

Everything after the message arrives.

One inbox for every channel, and the machinery to answer the questions your team shouldn't have to.

Keep what you already have

Your number, your phone, your history.

Linking by QR works the way WhatsApp Web does. Your phone carries on exactly as before, and Flash Chat sits alongside it as another linked device. Nobody has to change the number they have been giving customers for years.

Same number, no new SIM, no migration downtime
Keep replying from WhatsApp on the phone as normal
Import your existing chats so the inbox starts full
Unlink whenever you like — the number was always yours

AI replies

An assistant that cannot run up a bill.

Point it at your own documents and it answers from them. Set a monthly spend cap, and it warns you as you approach it, then switches itself off rather than quietly costing more.

How it works

From signing up to a live reply, in an afternoon.

No developer, no onboarding call, no waiting on an approval you cannot chase.

STEP 01

Connect a number

Scan a QR code with the phone in your pocket, or connect a Cloud API number if you already have one. Both take the same few minutes.

No approval needed on QR

STEP 02

Set what answers itself

Build a flow for the questions you answer every day, and let automations catch keywords and first-time messages.

Visual builder

STEP 03

Put your team on it

Invite everybody, assign the threads that need a person, and watch the rest handle themselves.

No per-seat charge

For developers

An API that covers what the dashboard covers.

Scoped keys, predictable JSON, and signed webhooks so your server can trust what it receives. Name a channel and the same call sends over WhatsApp or SMS.

FAQ

Questions worth asking first.

01Do I need approval from Meta to start?

Not on the QR route. You scan a code with the phone you already use and you can send straight away. Approval only matters if you want the official Cloud API, with its templates and verified badge, and you can add that later without losing anything.

02What is the catch with linking a phone?

Two things, and we would rather say them here. You cannot send Meta's message templates, so you cannot start a conversation with somebody who has not written to you first, and you do not get the green verified badge. For support and sales replies neither matters. For bulk notifications, use the Cloud API.

03Do I lose WhatsApp on my phone once I connect it?

No. A QR link is a companion device, exactly like WhatsApp Web, so the phone carries on as normal and you can keep answering from it. Flash Chat simply sees the same conversations. You can also import the chats you already have, so the inbox does not start empty.

04Can I use WhatsApp and SMS from the same place?

Yes. An SMS channel is just another connected number, so the same inbox, the same contacts and the same API call reach it. Name the channel in the request and the message goes out over that route.

05How does the SMS route actually send?

An Android app on a handset holding your SIM. Your operator carries the message and bills you for it, so the sender is genuinely your own number rather than a shared shortcode.

06Is there a charge per team member?

No. Plans are limited by what you send and store, not by how many people are signed in. Invite everybody who needs access and give them a role that fits.

07What happens when I hit a plan limit?

The limit is enforced rather than warned about, so sends stop instead of quietly becoming an overage bill. You will see which limit you reached and can move up a plan straight away.

08Can I build on top of it?

That is what the API is for. Forty-eight endpoints across nineteen resources, keys with scopes so an integration only gets what it needs, and signed webhooks so your server can verify that an event really came from us.
