You have tried to use the _old_ URL for this API

Please see the updated documentation

> **[Reference](https://dev.twitch.tv/docs/api/reference/#send-extension-chat-message)**
>
> Twitch Developer tools and services to integrate Twitch into your development or create interactive experience on twitch.tv.

For the URL and payload changes

Or an example: [https://github.com/BarryCarlyon/twitch\_misc/tree/main/extensions/chat](https://github.com/BarryCarlyon/twitch_misc/tree/main/extensions/chat)

I still get 404 with the following code

```auto
function chatMessage() {
    var url = "https://api.twitch.tv/helix/extensions/chat?broadcaster_id=" + channelID;
    console.log(url);
    var jwt = token;
    var id = clientId;
    var message = "test";

    fetch({
        method: 'POST',
        url: url,
        headers: {
            'Content-Type': "application/json",
            'Client-ID': id,
            'Authorization': "Bearer " + jwt,
        },
        body: { text: message }
    }).catch ((err) => {
        console.log(err);
    });
}

```

i changed only the url

is the extension installed and active on the text channel?

If you check the _body_ of the response it will help describe the issue

Uninstall the extension from the channel  
And install it and activate it into a slot again, in case the permission isn’t enabled right

![image](https://d2spem0quai2ol.cloudfront.net/original/3X/2/8/28d4d6b1e5b3e8282dc482a852068177593e8f90.png)

Then under manage permissions in the dashboard check the chat toggle is enabled

Then if it doesn’t work

Check the HTTP Body of the response, not just the HTTP Code

Also jsut realised your body is incomplete.

For Example:

```js
fetch(
    "https://api.twitch.tv/helix/extensions/chat",
    {
        method: "POST",
        headers: {
            "Client-ID": config.client_id,
            "Authorization": "Bearer " + sigChat,
            "Content-Type": 'application/json'
        },
        body: JSON.stringify({
            broadcaster_id: config.channel_id,
            text: "This is a Test Message Kappa",
            extension_id: config.client_id,
            extension_version: config.extension_version
        })
    }
)

Only the Broadcaster, or your EBS using a JWT you create/sign, can send Extension chat messages. Otherwise there would be nothing stopping any user from attempting to send malicious chat messages as your Extension.

</div>

Either your EBS using the Send Chat endpoint  
Or a chatbot

Which is basically the same thing in this scenario

Since you’ll need to get _the event_ from the extension to your backend.  
Then your backend can send it out on whatever your preference is
