Send post to WhatsApp Channel

Manage WhatsApp Channels via API

All Channel API Calls to work with WhatsApp channels: https://whapi.readme.io/reference/getnewsletters

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 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

curl --request GET \
     --url 'https://gate.whapi.cloud/newsletters?count=100' \
     --header 'accept: application/json' \
     --header 'authorization: Bearer iwc4s1vpNBhVbdSPwBczBDVCXo2bBmcs'

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:

💬 Send text messageWhapi Cloud - Whatsapp API for developers

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

curl --request POST \
     --url https://gate.whapi.cloud/messages/text \
     --header 'accept: application/json' \
     --header 'authorization: Bearer iwc4s1vpNBhVbdSPwBczBDVCXo2bBmcs' \
     --header 'content-type: application/json' \
     --data '
{
  "to": "120208836317406034@newsletter",
  "body": "Hello, World!"
}
