How to send a post to WhatsApp Channel via API

Our Cloud API supports WhatsApp Channels, a brand-new feature introduced by WhatsApp. It’s a unidirectional broadcast tool where administrators can send text, photos, videos, stickers, and polls. And users receive push notifications of updates from the channel like a private message.

To work with our service, you need to have an account and connect any number to an available channel on the dashboard. In order to automate WhatsApp, you need to sync our API with your phone number. Here's how: navigate to your personal dashboard, select your channel, and get a QR code there.

To send a message to the channel you need to know the channel ID.

In order to find out the identifier use the following method: GET /newsletters

import requests

url = "https://gate.whapi.cloud/newsletters?count=100"

headers = {
    "accept": "application/json",
    "authorization": "Bearer iBNBwpo21BDCsbdvVwShV4czcXPbBmcs"
}

response = requests.get(url, headers=headers)

print(response.text)

The channel ID looks like this: 120363171744447809@newsletter

Once you know the channel ID, you can use the method to send any message. For example, a text message:

import requests

url = "https://gate.whapi.cloud/messages/text"

payload = {
    "typing_time": 0,
    "to": "120363171744447809@newsletter",
    "body": "Hello, world!"
}
headers = {
    "accept": "application/json",
    "content-type": "application/json",
    "authorization": "Bearer iBNBwpo21BDCsbdvVwShV4czcXPbBmcs"
}

response = requests.post(url, json=payload, headers=headers)

print(response.text)

In the “to” parameter you insert the ID of the channel ( 120363171744447809@newsletter ) you want to send the message to. And in the “body”, the text of the message.
