whatsapp-api-client-python is a library for integration with WhatsApp messenger using the API service green-api.com. You should get a registration token and an account ID in your personal cabinet to use the library. There is a free developer account tariff.

API

The documentation for the REST API can be found at the link. The library is a wrapper for the REST API, so the documentation at the link above also applies.

Authorization

To send a message or perform other GREEN API methods, the WhatsApp account in the phone app must be authorized. To authorize the account, go to your cabinet and scan the QR code using the WhatsApp app.

Installation

python -m pip install whatsapp-api-client-python

Import

from whatsapp_api_client_python import API

Examples

How to initialize an object

greenAPI = API.GreenAPI(
    "1101000001", "d75b3a66374942c5b3c019c698abc2067e151558acbd412345"
)

Sending a text message to a WhatsApp number

Link to example: sendTextMessage.py.

response = greenAPI.sending.sendMessage("11001234567@c.us", "Message text")

print(response.data)

Sending an image via URL

Link to example: sendPictureByLink.py.

response = greenAPI.sending.sendFileByUrl(
    "11001234567@c.us",
    "https://download.samplelib.com/png/sample-clouds2-400x300.png",
    "sample-clouds2-400x300.png",
    "Sample PNG"
)

print(response.data)

Sending an image by uploading from the disk

Link to example: sendPictureByUpload.py.

response = greenAPI.sending.sendFileByUpload(
    "11001234567@c.us",
    "data/rates.png",
    "rates.png",
    "Available rates"
)

print(response.data)

Group creation and sending a message to the group

Attention. If one tries to create a group with a non-existent number, WhatsApp may block the sender's number. The number in the example is non-existent.

Link to example: createGroupAndSendMessage.py.

create_group_response = greenAPI.groups.createGroup(
    "Group Name", ["11001234567@c.us"]
)
if create_group_response.code == 200:
    send_message_response = greenAPI.sending.sendMessage(
        create_group_response.data["chatId"], "Message text"
    )

Receive incoming messages by HTTP API

Link to example: receiveNotification.py.

The general concept of receiving data in the GREEN API is described here. To start receiving notifications by the HTTP API you need to execute the library method:

greenAPI.webhooks.startReceivingNotifications(onEvent)

onEvent - your function which should contain parameters:

Parameter	Description
typeWebhook	received notification type (str)
body	notification body (dict)

Notification body types and formats can be found here.

This method will be called when an incoming notification is received. Next, process notifications according to the business logic of your system.

Sending a polling message

Link to example: sendPoll.py.

response = greenAPI.sending.sendPoll(
    "11001234567@c.us",
    "Please choose a color:",
    [
        {"optionName": "Red"},
        {"optionName": "Green"},
        {"optionName": "Blue"}
    ]
)

print(response.data)
