Complete WhatsApp Business API Platform

It is the way Meta lets software talk to WhatsApp. There is no app to install. You connect a phone number to a platform like this one, and from then on you work in a console and, if you want, through code. It exists for businesses that get more messages than one person can answer, or that want messages sent automatically from their own systems.

The free app is one phone, one person, and you can only reply to people who wrote to you first. The API removes all three limits. If one person can comfortably keep up with your WhatsApp, stay on the free app — it is genuinely good, and you do not need this.

Minutes. We are an approved Meta Tech Provider, so you sign in through Meta's own window, pick your number, and templates and the API are switched on. The green tick is a separate Meta review with its own timetable, and your number works without it.

Yes, as long as it is not signed in to the WhatsApp app or the WhatsApp Business app right now. If it is, delete that account first, then connect the number here. A number can only be in one place at a time.

Not if you send to people who agreed to hear from you. Bans come from people marking your messages as spam. Every contact carries its consent status, an opt-out drops that person from your next send, and a do-not-contact list you keep overrides everything else.

Meta decides that, not us. New numbers start on a low daily limit for messages you begin, and Meta raises it in steps as you keep sending without people reporting you. Replies to customers who messaged you first are not capped. The way to move up quickly is boring but real: only message people who agreed to it, and give them something worth reading.

Daily — a rolling 24 hours. It counts the unique people your business starts conversations with, not the number of messages, and it is shared across all your numbers. Meta's tiers are 250, 2,000, 10,000, 100,000 and unlimited. Verifying your business is the fastest way from 250 to 2,000.

In ThinnestAI, open Connect WhatsApp: Your WhatsApp account lists your business's daily limit, with your verification, quality and display name beside it. An older per-number figure, often 250, can still appear in places — Meta now sets limits per business, and the business-wide figure is the one that counts. Many businesses showing 250 per number are already at 2,000.

Two parts. Meta charges per message at rates it publishes for each country and changes itself, and every provider passes on the same Meta charges. On top of that we charge our platform fee, and the AI agent is billed on what you use. The rates for your region are on the pricing page.

Yes. The API works for businesses in any country, and we are an approved Meta Tech Provider, so a business in the US, the UK, the UAE or elsewhere connects its number through Meta's own signup in minutes. International workspaces are billed in US dollars; Indian workspaces are billed in rupees.

No. Plenty of businesses use the API for broadcasts and a shared inbox and never switch the agent on. It is there when you want replies handled for you — and it is the same agent that answers your phone line and your website chat.

No. We connect straight to Meta's Cloud API as an approved Tech Provider. There is no other company sitting between you and Meta.

Sent means WhatsApp accepted it; delivered means it reached a phone. The most common gap is WhatsApp's own limit on marketing messages per person (error 131049), which applies on every platform. Every undelivered message shows WhatsApp's exact reason, with what it means underneath.

WhatsApp limits how many marketing messages each person receives from all businesses combined, and this person is at that limit for now. It isn't your account or template. Wait at least 24 hours before marketing to them again — we hold them back from your next broadcast automatically so a resend doesn't extend the block.

WhatsApp shows your business name once Meta approves your display name. Until then it shows the number. Approval is Meta's and can take a few days, and the name has to match your business. In ThinnestAI you can ask for a new display name yourself: open Connect WhatsApp, click Display name, send the new name to Meta for review, and press Start using once Meta approves it.

Open Dashboard under WhatsApp in ThinnestAI. Pick 24 hours, 7 days, 30 days or any dates on the calendar, and it shows messages sent, delivered, read, not delivered and received, what they cost, and the most common reasons messages were not delivered.

It is an optional Meta programme that can deliver more of your marketing templates and report clicks. Connect WhatsApp shows whether your business is on it, and Set up opens Meta in a small window where an admin of your business accepts its terms, without leaving ThinnestAI. Once on, ThinnestAI sends your marketing templates through it automatically.

Click Blue tick on Connect WhatsApp in ThinnestAI. It reads from Meta whether your number meets Meta's five requirements: policy compliance, 30 days on the platform, a verified business, two-step verification and an approved display name, and tells you what is missing and from when. Meta reviews each request and decides, so the links to news coverage of your brand matter most.

That's error 131042: Meta couldn't charge the payment method on your WhatsApp Business account. Update the payment method Meta holds for that account and sending resumes on its own.

No. A message WhatsApp didn't deliver isn't charged.

Yes. On the Contacts page, each contact shows what became of their last WhatsApp campaign message, and you can filter by it — Delivered, Read, Replied, Not delivered, Failed, Not contacted or Never messaged — with a count for each. A broadcast's own page filters its recipients the same way, and shows WhatsApp's reason for each one that wasn't delivered.
