WAHA, Free Self-Hosted WhatsApp API, supports WhatsApp Channels, a brand-new feature introduced by WhatsApp.
It is a one-way broadcast tool that allows administrators to send various content types such as text, photos, videos, and polls.
Users receive push notifications from the channel, similar to a private message.
In this article, we give you a Step-By-Step guide how to send messages to WhatsApp Channels using WAHA - free, self-hosted WhatsApp API!
We'll install it on your own laptop or server, so no suspicious services have access to your WhatsApp account.
Step 0. Requirements
WAHA works on top of Docker, that's the only think you'll need!
👉 Please follow the
Docker official guides to install it on Linux, Windows, and macOS
Why Docker?
Docker makes it easy to ship all-in-one solution with the runtime and dependencies. You don't have to worry about language-specific libraries or chrome installation.
Also, Docker makes installation and update processes so simple, just one command!
Step 1. Run WAHA
After you installed Docker - you're ready to run WAHA!
docker run -it --rm -p 3000:3000/tcp --name waha devlikeapro/waha
# It prints logs and the last line must be
# WhatsApp API is running on: http://[::1]:3000
It may take time to download the image, depending on your internet speed.
If you're using ARM processor (like Apple M1/M2) run the following commands instead:
# Download the image
docker pull devlikeapro/waha:arm
# Rename it, so you can use devlikeapro/waha image in other place
docker tag devlikeapro/waha:arm devlikeapro/waha
# Run the same command!
docker run -it --rm -p 3000:3000/tcp --name waha devlikeapro/waha
# It prints logs and the last line must be
# WhatsApp API is running on: http://[::1]:3000
👉 Now, open Dashboard at
http://localhost:3000/dashboard
You'll see WAHA Dashboard:
Step 2. Run session
Now you start default session (current status should be STOPPED).
You can leave all configuration parameters by default:
Step 3. Scan QR
Wait until the session status is SCAN_QR and click on "camera" icon:
👉 If instead of QR you see Click to reload QR - stop the session and start it again.
You'll see QR code from WhatsApp Web app, now get your phone with installed WhatsApp application and scan the QR:
The session status will move to WORKING status:
Step 4. Get Channel ID
One step before you can send a message to you Channel - you need to get Channel ID in format 123123123@newsletter
to know where to send a message.
You can just execute the following curl command:
curl -X 'GET' \
'http://localhost:3000/api/default/channels?role=OWNER' \
-H 'accept: application/json'
In the response you'll see all channels, choose one and copy id:
[
{
"id": "111111111111111111@newsletter", // <========= copy that
"name": "Channel Name",
"role": "OWNER",
...
}
]
As alternative to curl, you can use WAHA Swagger for that, open it at
http://localhost:3000/#/channels
, scroll down to Channels section.
- Find
GET /api/{session}/channelsendpoint and expand it - Click Try it out
- Choose
role=OWNERif you have your own channels orrole=ADMINif you're admin in the channel (you can not send messages if you'reSUBSCRIBERin the channel) - Click Execute
Step 5. Send a message to WhatsApp Channel
Now we're ready to send first messages to WhatsApp Channel via API!
Replace 123123@newsletter with your newsletter id, like 29847512@newsletter in the bellow command:
curl -X 'POST' \
'http://localhost:3000/api/sendText' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"chatId": "123123123123@newsletter",
"text": "Hi there!",
"session": "default"
}'
As alternative to curl, you can use WAHA Swagger for that, open it at
http://localhost:3000/#/chatting
, scroll down to chatting section.
- Find
POST /api/sendTextendpoint and expand it - Click Try it out
- Replace
123123@newsletterwith your newsletter id, like29847512@newsletterin the bellow command - Click Execute
