🚀 **How to Automate WhatsApp Channels (newsletters) with API | Whapi.Cloud Demo via Postman**
{% endembed %}

Our Cloud API supports WhatsApp Channels (newsletters), a brand-new feature introduced by WhatsApp. It’s a unidirectional broadcast tool where administrators can send text, photos, videos, voices,  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](https://whapi.readme.io/reference/getnewsletters)

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

The channel (newsletter) ID looks like this: `120363171744447809@newsletter`&#x20;

Once you know the channel ID, you can use the method to send any message. For example, a text message:&#x20;

{% embed url="<https://whapi.readme.io/reference/sendmessagetext>" %}

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

```sh
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!"
}
'
```
