I want to use a PHP form to update my Twitch channel’s “Title” and “Category” (Game) like on the Twitch Live Dashboard, except on my own form with just those two fields.

I understand that I need to use the commands at [https://dev.twitch.tv/docs/v5/reference/channels/#update-channel](https://dev.twitch.tv/docs/v5/reference/channels/#update-channel) but I have no clue how to. Can someone please help me?

Convert

```auto
curl -H 'Client-ID: uo6dggojyb8d6soh92zknwmi5ej1q2' \
-H 'Accept: application/vnd.twitchtv.v5+json' \
-H 'Authorization: OAuth cfabdegwdoklmawdzdo98xt2fo512y' \
-d 'channel[status]=The+Finalest+of+Fantasies&channel[game]=Final+Fantasy+XV&channel[channel_feed_enabled]=false' \

```

to a PHP cURL request.

You will need to have done an oAuth loop first

I am a bit confused since its a PUT request and with the OAuth loop I am a bit lost. Would you be able to help me with the actual code in PHP. Many thanks for the quick response.

Here is a none tested, not to be used in production, one pager example that should work.

```

I’d suggest learning the basics of PHP before trying to do something advanced such as this.

Hi thanks so much for this. I used the code and replaced the values as needed. It logs in fine, authorized the account as well and returns to the form to update but after I fill and click Submit it gives me the error “An Error Occured”. Cant seem to figure out why. Is there some permission thats not given?

Tried adding `scope=channel_editor` in the Login link as follows but its still the same as earlier.

`<a href="https://id.twitch.tv/oauth2/authorize?client_id=<?php echo $client_id; ?>&redirect_uri=<?php echo $redirect_uri; ?>&response_type=code&scope=channel_editor">Login</a>`

You might be right on the scope.

My understanding is you ONLY need the scope if you are updating someone else’s channel. If you are updating your own it should work without it. (But I don’t run code to update my own channel and this example is illustrative of what should work and should not be used in production)

Consider adapting

```
    if ($i['http_code'] == 200) {
        echo 'OK';
    } else {
        echo 'An Error Occured';
    }

```

to

```
    if ($i['http_code'] == 200) {
        echo 'OK';
    } else {
        echo 'An Error Occured ' . $i['http_code'] . ' - ' . $r;
    }

```

To spit out whatever the error is

I expect the issue is that

```
    curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode([
        'status' => $_POST['status'],
        'game' => $_POST['game']
    ]));

```

Should be, as I built the POST payload wrong.

```
    curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode([
        'channel' => [
            'status' => $_POST['status'],
            'game' => $_POST['game']
         ]
    ]));

```

Additionally:

```
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'Authorization: OAuth ' . $_SESSION['twitch']['access_token'],
        'Content-Type: application/json'
    ));

```

should be

```
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'Authorization: OAuth ' . $_SESSION['twitch']['access_token'],
        'Accept: application/vnd.twitchtv.v5+json',
        'Content-Type: application/json'
    ));
```
