Twitch API user endpoint returns empty response in PHP

I’m having trouble with a Twitch API call in PHP. My code seems fine and curl doesn’t throw any errors, but I keep getting an empty response instead of actual user data.

public function fetchUserData() {
    $apiUrl = $this->TwitchClient->buildUrl("USER_ENDPOINT");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $apiUrl);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: OAuth " . $this->token));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $response = curl_exec($ch);
    if (curl_errno($ch)) {
        echo "Request failed: " . curl_error($ch);
        return;
    }
    curl_close($ch);
    
    $this->userData = json_decode($response);
}

The variable ends up being empty even though no curl errors occur. What could be causing this issue?

make sure your token has the correct scopes for accessing user data. Also, Twitch updated their auth header, so try using "Authorization: Bearer " . $this->token instead of the OAuth prefix. it helped me fix a similar problem.
