Offer WhatsApp in your software without building billing
With bZapper Connect your customer creates the account, subscribes to Pro and connects WhatsApp without leaving your screen — and your backend receives their API key. One webhook for every customer.
Offer WhatsApp inside your software
Your customer subscribes to bZapper Pro and connects their number without leaving your product. You receive the API key they authorized and start sending and receiving messages right away.
- 1
One-click account
The component opens with the details your product already has. No password, no captcha, no email confirmation.
- 2
Pro subscription
Card or Pix, right there. The customer pays bZapper directly — you never handle billing.
- 3
WhatsApp connected
QR code or pairing code, with live status. At the end, your backend receives the API key.
One line on the front end
Modal or inline, in Shadow DOM: it never clashes with your product’s CSS.
One webhook for all
Messages and status for all your customers on a single endpoint, tagged with your own customer id.
Automatic suspension
If the customer’s Pro goes unpaid, the key answers 402 and resumes by itself once they pay.
In all 7 SDKs
Node, Python, PHP, .NET (C#), Java, Go and Ruby already ship the partner client.
What your product needs to write:
// 1. your backend opens the session with the partner secret
const { session_token } = await api.post('/bzapper/session')
// 2. the customer subscribes and connects without leaving your screen
BzapperConnect.open({
session: session_token,
onComplete: ({ code }) => api.post('/bzapper/exchange', { code }),
})
// 3. your backend exchanges the code for the customer API key
// → { api_key: "bz_live_…", status: "active" }The partner secret and the API key stay on your backend. The browser gets a 30-minute ticket that only works on your domains. The partner key operates WhatsApp but never touches the customer’s plan, users or billing.
