Missing Client-ID error when accessing https://api.twitch.tv/helix/moderation/bans

API
1

I am trying to create a PHP function to enable me to ban a user but I keep getting the error msg

“error”:“Unauthorized”,“status”:401,“message”:“Client ID is missing”

As far as I can tell I am doing everything correctly and I am passing in my client id so I am confused as to why this is failing despite attempting to find working examples online and double-checking my code. I am sure its something simple that I am missing:

function banUser($user_id) {
global $client_id;
global $broadcaster_id;

$data = array('user_id:' => $user_id,'reason:' => 'no reason');
$data = json_encode($data);
$len = strlen($data);

$ch = curl_init( 'https://api.twitch.tv/helix/moderation/bans?broadcaster_id='.$broadcaster_id.'&moderator_id='.$broadcaster_id.'' );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $data );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Client-Id:' => $client_id,
    'Authorization: Bearer '. $_SESSION['access_token'],        
    'Content-length: '.$len
));
   
$result = curl_exec($ch);
$i = curl_getinfo($ch);
curl_close($ch);

echo "<pre>$result</pre>";


if ($i['http_code'] == 200) {
    return true;
            
} else {
    $errormsg = "FUNCTION banUser() THREW AN EXCEPTION: ".$i['http_code']."";
    displayErrorMsg($errormsg);
}

}

I am passing a valid Oauth Access Token, I do have the correct scope including moderator:manage:banned_users, I am passing in the user_id for an existing twitch account, and I am able to do everything else without any problems in my app, so I am confused as to whats happening here.

should be

curl_setopt( $ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Client-Id: ' . $client_id,
    'Authorization: Bearer '. $_SESSION['access_token'],        
    'Content-length: '.$len
));

You were missing a space after the : of client-id and doing a => instead of string concat

Thanks for the almost immediate response Barry. That got me past that error, now it returns:

“error”:“Bad Request”,“status”:400,“message”:“Missing required parameter "user_id"”

And yes I went and added a space after user_id: and reason: :stuck_out_tongue:

Does it need to be shown as "User-Id: "?

should be

$data = array('user_id' => $user_id,'reason' => 'no reason');

No : in the keys in the associative array needed.

Okay fixed that however its still returning the same error

“error”:“Bad Request”,“status”:400,“message”:“Missing required parameter "user_id"”

if I print_r($data) I get the user_id for the account I am testing for bans, so the data should be present

So what is your current code looking like now?

Here:

function banUser($user_id) {
global $client_id;
global $broadcaster_id;

# FROM: https://dev.twitch.tv/docs/api/reference/#ban-user

$data = array('user_id ' => $user_id,'reason ' => 'no reason');
$data = json_encode($data);
$len = strlen($data);

print_r($data);

$ch = curl_init( 'https://api.twitch.tv/helix/moderation/bans?broadcaster_id='.$broadcaster_id.'&moderator_id='.$broadcaster_id.'' );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $data );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Client-Id: '. $client_id,
    'Authorization: Bearer '. $_SESSION['access_token'],        
    'Content-length: '.$len
));


$result = curl_exec($ch);
$i = curl_getinfo($ch);
curl_close($ch);

echo "<pre>$result</pre>";
//echo "<hr>";
//print_r($i);

if ($i['http_code'] == 200) {
    return true;
            
} else {
    $errormsg = "FUNCTION banUser() THREW AN EXCEPTION: ".$i['http_code']."";
    displayErrorMsg($errormsg);
}

}

Ah I see the issue, forgot that ban needs a nest

$data = array('user_id ' => $user_id,'reason ' => 'no reason');

should be

$data = array('data' => array('user_id ' => $user_id,'reason ' => 'no reason'));

Okay made that change, but still same error msg:

“error”:“Bad Request”,“status”:400,“message”:“Missing required parameter "user_id"”

we snuck a space in after after the user_id (and the reason) keys in the payload

$data = array('data' => array('user_id' => $user_id,'reason' => 'no reason'));

Oh thats on me: “Insufficient Coffee Error In Operator” :slight_smile:

Thanks immensely, been trying to figure this out for a few days. It now looks like its all working correctly!
