Email notifications get ignored. Push notifications get disabled. WhatsApp messages get read.

WA Bridges lets you send programmatic notifications to any WhatsApp number from your backend — no approval queue, no template restrictions, no per-message fees. Provision a bridge, pair a spare WhatsApp number, and you're live in under 60 seconds.

How it works

1
Provision a bridge
One API call creates a bridge — a containerized WhatsApp connection you control. Takes under 60 seconds.
2
Pair a number
Scan a QR code with any WhatsApp number. Personal numbers work. Business numbers work. That number is now under API control.
3
Send from your backend
POST to the send endpoint with the recipient number and message body. No SDK, no library — plain HTTP.
4
Receive delivery receipts
Configure a webhook URL and we'll POST delivery status events back to your server as messages are delivered and read.

I want to send WhatsApp notifications from my backend using WA Bridges.

My stack: [Node.js / Python / Ruby / Go — update this]
My use case: sending order confirmation messages when a customer places an order.

I already have:
- A WA Bridges API key stored as the env var WA_API_KEY
- A bridge provisioned with customer_ref "notifications"
- The recipient phone number in E.164 format (e.g. +15551234567)

Please read the WA Bridges API docs before writing any code:
https://wabridges.com/docs.txt

Then write me a reusable notify(phone, message) function and show me
how to call it for three scenarios: order confirmed, server alert, and
a failed payment. Keep it simple — no SDK, just HTTP.
