WhatsApp HTTP API that you can configure in a click! It's really Free! :)

The article Make a WhatsApp Bot Via HTTP API For Free And Fun! on Medium about this repository.

You can go through currently supported methods in Swagger The project is an HTTP wrapper around https://github.com/orkestral/venom, so we can also support these methods:

Only thing that you must have - installed docker. Please follow the original instruction how to install docker

docker pull allburov/whatsapp-http-api

Run WhatsApp HTTP API:

docker run -it -v `pwd`/tokens:/app/tokens -p 127.0.0.1:3000:3000/tcp allburov/whatsapp-http-api

If you are not logged in, it will print a QR code in the terminal. Scan it with your phone and you are ready to go! How to log in - the instruction on WhatsApp site We will remember the session so there is no need to authenticate everytime.

After that open in a browser the link and you'll see Swagger (OpenApi) API specification for WhatsApp HTTP API http://localhost:3000/#/

Let's try to send a message:

# Phone without +
export PHONE=79776772457
curl -d "{\"chatId\": \"${PHONE}@c.us\", \"text\": \"Hello from WhatsApp HTTP API Free\" }" -H "Content-Type: application/json" -X POST http://localhost:3000/api/sendText

Go to the "screenshot" section and get a screenshot http://localhost:3000/#/screenshot

To show how to receive messages we'll create a simple "echo" server with two functions:

1. When we receive a text message - just send the text back
2. When we receive a message with a file (an image, a voice message) - download it and send the path back

In order to send you messages we use webhooks and configure them via environments variables. So what you need to create "echo" server is HTTP server that will receive JSON POST request and then call back WhatsApp HTTP API via POST /api/sendText endpoint with JSON body.

We use Python. Feel free to create your favorite language example and contribute to the project!

Run "echo" server in one terminal and leave it working:

# if you haven't already
git clone https://github.com/allburov/whatsapp-http-api.git 
cd whatsapp-http-api
python -mpip install -r examples/requirements.txt
export FLASK_APP=examples/echo.py
flask run

Visit http://localhost:5000 and check that we are good to go further.

Let's start WhatsApp HTTP API and configure the "on message" webhook and point it on our "http://localhost:5000/message" endpoint:

docker run -it -v `pwd`/tokens:/app/tokens --network=host -e WHATSAPP_HOOK_ONMESSAGE=http://localhost:5000/message allburov/whatsapp-http-api

Now go ahead, open the second whatsapp and send to our WhatsApp HTTP API a text message! It must reply the same text.

If you try to send an image the "echo server" will send a path to the downloaded file.

• DEBUG - show debug and verbose logs, set in any value
• WHATSAPP_API_PORT - listen port for HTTP server (default: 3000)
• WHATSAPP_API_HOSTNAME - Hostname for HTTP server (default: localhost)

The description of webhooks you can in Venom README.md, section Events

All webhooks are disabled by default:

• WHATSAPP_HOOK_ONMESSAGE=http://localhost/uri
• WHATSAPP_HOOK_ONSTATECHANGE=http://localhost/uri
• WHATSAPP_HOOK_ONACK=http://localhost/uri
• WHATSAPP_HOOK_ONADDEDTOGROUP=http://localhost/uri

• WHATSAPP_FILES_FOLDER - folder where will be stored files from chats (images, voice messages) ( default: /tmp/whatsapp-files)
• WHATSAPP_FILES_MIMETYPES - download only these mimetypes from messages (download all files be default). Mimetypes must be separated by a comma, without spaces: audio,image/png,image/gif. In order to choose type use prefix ( like audio,image).
• WHATSAPP_FILES_LIFETIME- to keep free space files will be removed after this time (default: 180, in seconds)
