WAservix WhatsApp API Gateway - official Python client: send WhatsApp messages from your own number. By Tekservix.

Python client for the WAservix WhatsApp API Gateway.

WAservix links your own WhatsApp number by QR code (the same way WhatsApp Web does) and gives you a REST API to send text, images, video, audio, documents, locations, polls and more, with webhooks for incoming messages and status updates.

• Zero dependencies (standard library only), Python 3.8+
• Works in Django, Flask, FastAPI, scripts and cron jobs
• Webhook check built in

Install

pip install waservix

Quick start

Copy your device's API key from the WAservix dashboard (Devices -> API key) and keep it on your server.

import os
from waservix import WAservix

wa = WAservix(api_key=os.environ["WASERVIX_KEY"])

result = wa.send_text("+15551234567", "Hello Aline, your order is ready")
print(result["msgId"], result["status"])  # 58213 in_progress

Sending

Messages are queued and sent one at a time per number, so each call returns right away with status: "in_progress" and a msgId.

# Image with caption
wa.send_image("+15551234567", "https://example.com/product.jpg", caption="Back in stock")

# Document
wa.send_document("+15551234567", "https://example.com/inv-1042.pdf",
                 file_name="Invoice-1042.pdf", caption="Your invoice")

# Anything the API supports, including groups (JID ending in @g.us)
wa.send_message("120363040000000000@g.us", text="Team meeting at 3pm")
wa.send_message("+15551234567", location={"latitude": -1.9441, "longitude": 30.0619, "name": "Our shop"})

Status, contacts and groups

info = wa.get_message_info(58213)      # queued, sent, delivered, read, played or failed
check = wa.on_whatsapp("+15551234567")  # {"exists": True, "jid": "..."}
conn = wa.get_status()                  # {"status": "connected"}

wa.edit_message(58213, "Corrected text")  # own text messages, about 15 minutes
groups = wa.list_groups()

Anything else in the API reference is one call away:

wa.request("POST", "/messages/read", {"msgId": "3EB0X123456789"})

Webhooks

Set a webhook URL and events for the number in the dashboard. Each request carries X-Webhook-Signature, which equals the device's webhook secret. Flask example:

import os
from flask import Flask, request, abort
from waservix import verify_webhook

app = Flask(__name__)

@app.post("/wa/webhook")
def wa_webhook():
    if not verify_webhook(request.headers.get("X-Webhook-Signature"), os.environ["WASERVIX_WEBHOOK_SECRET"]):
        abort(401)
    payload = request.get_json()
    if payload["event"] == "messages.received":
        m = payload["data"]["messages"]
        print(m["key"]["cleanedSenderPn"], m["messageBody"])
    return "", 200  # acknowledge fast; queue slow work

Errors

Failed calls raise WAservixError with status, message, field errors and, on 429, retry_after in seconds. A 503 means the device is reconnecting: retry shortly.

Never ship the key inside a browser or mobile app: anyone could read it. Call the API from your server.

Migrating from WaSender

WAservix accepts the same /send-message body and webhook fields as WaSender, so most integrations switch by changing the base URL and key. See the compatibility notes.

Use it responsibly

WAservix is not Meta's official WhatsApp Business Platform. There's no business verification and no per-conversation fee, but WhatsApp's spam rules apply to your number directly. Message people who expect to hear from you, warm up new numbers slowly and keep the built-in account protection on.
