Your customers connect WhatsApp inside your system
The bZapper embeddable widget: one line of HTML and your customers connect, disconnect and monitor their own numbers without leaving your product. Public key locked to your origins.
Put number management right inside your product
A standalone widget you embed in your own system. Your customers connect, disconnect and track the project numbers — with zero UI to build on your side. One line of code.
Project numbers
Automatically loads the connected numbers of the project tied to the key. Each one with live status.
Connect via QR
The customer scans the QR and connects a new number right there — add a number (if the plan allows) or disconnect, all inside the widget.
Mini dashboard
Project usage at a glance: messages, numbers and storage for the period. Billing stays in the panel.
Origin-locked
The wgt_ key is public, but locked to an origin allowlist (CORS). It never exposes your real API key.
Floating (plug-and-play)
A bubble in the corner of the screen. Just paste the <script> with your key — it opens with one click.
Embedded (inline)
Render <bzapper-widget> anywhere on your page, like a native block of your own dashboard.
Floating mode — one line in your HTML:
<!-- paste before </body> -->
<script src="https://widget.bzapper.com.br/v1/widget.js"
data-key="wgt_sua_chave" async></script>The wgt_ key is public (it ships in the HTML) and locked to an origin allowlist you configure in the panel. Your real API key never shows up. Billing (plans and invoices) stays in the panel — the widget only manages connections.
