Twitter API returning 400 Bad Request error consistently

I’m trying to fetch tweets using the Twitter API, but I keep getting a 400 Bad Request error. Here’s what I’ve done:

$api_url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
$params = [
    "screen_name" => $handle,
    "count" => $tweet_count
];

$full_url = $api_url . "?" . http_build_query($params);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $full_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

if ($response) {
    $tweets = json_decode($response, true);
    // Process tweets
} else {
    // Handle error
}

I’ve double-checked the URL, and it looks correct. The error message says:

HTTP request failed! HTTP/1.1 400 Bad Request

What could be causing this? Do I need to use OAuth for basic tweet retrieval? Is there some kind of registration process I’m missing? I’m using a shared hosting provider, if that matters.

Any help would be appreciated. Thanks!

I encountered a similar issue when working with the Twitter API recently. The 400 Bad Request error is typically triggered by missing or incorrect authentication credentials, so registering your application on the Twitter Developer Portal to obtain your API key, API secret key, access token, and access token secret is essential. To manage the OAuth 1.0a process easily, consider using a library like TwitterOAuth. Also, make sure you are using HTTPS for all API calls and that your server’s clock is synchronized. Checking your API rate limits could also shed some light on the problem.

I’ve been down this road before and it’s a common stumbling block. The 400 error usually indicates that proper authentication is missing, as Twitter’s API is quite strict. In my experience, the solution was to set up OAuth 1.0a for my requests. I registered my app on the Twitter Developer Portal, obtained the necessary API key, secret, access token, and token secret, and then used a library like TwitterOAuth to manage the process. Also, ensuring that HTTPS is used and that the server’s time is synchronized helped resolve issues related to Twitter’s picky timestamp requirements. If problems persist, it’s worth verifying that you’re not hitting rate limits and that you’re using the current API version.

hey mate, sounds like ur missing the OAuth authentication. Twitter API needs that for all requests now. You gotta set up an app on their dev portal, get ur API keys, and use em to authenticate. Also, make sure ur using the latest API version (v2). good luck!
