WhatsApp API

Automate WhatsApp from your existing number. Connect by scanning a QR code, then send and receive messages through one REST API. No Meta business application, no template approval, no per-message template fees.

How it works

Create a session, open the QR code, and scan it with the WhatsApp app on your phone (the same pairing flow as WhatsApp Web). Your number is connected in minutes and ready to send and receive messages via the API. See the API docs to get started.

Frequently asked questions

Is this the official WhatsApp Business API (Cloud API)?

No. SendAPI connects your existing WhatsApp number through a secure session that you pair by scanning a QR code, similar to WhatsApp Web. You automate messaging through our REST API without applying to become a Meta Business Solution Provider or getting templates approved.

Do I need Meta approval or message templates?

No. There is no Meta application and no template approval step. Connect your number and start sending right away.

How fast can I go live?

Usually within minutes. Create a session, scan the QR code with your phone, and send your first message.

Can my WhatsApp number get flagged?

WhatsApp applies its own anti-spam limits to every number. Message people who expect to hear from you and keep volume reasonable. SendAPI paces bulk sends automatically to reduce the risk.

How many numbers can I connect?

Each connected number is a session: 1 on Starter, 3 on Growth, 10 on Business, unlimited on Enterprise.
