PYTHON QUICKSTART
Send your first WhatsApp message in under 5 minutes. You need a WA Bridges API key - get one from the dashboard.
1. INSTALL
SHELL
pip install requests flask
ENV
export WA_API_KEY="sk_..."
2. PROVISION A BRIDGE
One bridge = one WhatsApp number. customer_ref is your internal identifier (user ID, slug, etc.).
PYTHON
import os
import requests
API_KEY = os.environ['WA_API_KEY']
BASE = 'https://wabridges.com/api'
HEADERS = {'Authorization': f'Bearer {API_KEY}'}
def provision(customer_ref, webhook_url):
r = requests.post(f'{BASE}/instances', json={
'customer_ref': customer_ref,
'webhook_url': webhook_url,
}, headers=HEADERS)
r.raise_for_status()
return r.json() # { 'id', 'customer_ref', 'state' }
bridge = provision('user-123', 'https://yourbackend.com/hook')
print(bridge)
RESPONSE
{"id": 42, "customer_ref": "user-123", "state": "running"}
3. PAIR A PHONE
Request a pairing code. Open WhatsApp on the phone, go to Linked Devices → Link a device → Link with phone number, then enter the code.
PYTHON
def pair(customer_ref, phone):
r = requests.post(
f'{BASE}/instances/{customer_ref}/proxy/pair',
json={'phone': phone},
headers=HEADERS
)
r.raise_for_status()
return r.json()['code'] # "ABCD-EFGH"
code = pair('user-123', '15550001234')
print(f'Enter this code on the phone: {code}')
RESPONSE
{"code": "ABCD-EFGH"}
Once paired, the bridge fires a connected webhook event. Poll /proxy/status or wait for the event.
4. SEND A MESSAGE
PYTHON
def send_text(customer_ref, to, body):
r = requests.post(
f'{BASE}/instances/{customer_ref}/proxy/send/text',
json={'chat': to, 'body': body},
headers=HEADERS
)
r.raise_for_status()
return r.json() # { 'message_id', 'timestamp' }
send_text('user-123', '15559876543', 'Hello from the API!')
RESPONSE
{"message_id": "ACE41E...", "timestamp": 1777180605}
5. RECEIVE EVENTS
Inbound messages and events are delivered via POST to your webhook_url. Return 200 immediately.
PYTHON
from flask import Flask, request
import threading
app = Flask(__name__)
def handle(payload):
if payload.get('event') == 'message' and not payload.get('from_me'):
print(f"{payload['name']}: {payload['body']}")
@app.route('/hook', methods=['POST'])
def webhook():
payload = request.get_json()
threading.Thread(target=handle, args=(payload,)).start()
return '', 200
See the webhook guide for all event types and fields.
