There is no mention of tweet_mode at https://developer.twitter.com/en/docs/tweets/timelines/api-reference/get-statuses-user_timeline.html
I am wondering if perhaps I am using the wrong API to be able to take advantage of tweet_mode?
In my application, I supplied the tweet_mode=extended argument and it had no effect. My code...
// Load the Tweets.
$args = array(
'screen_name' => $username,
'exclude_replies' => 'true',
'include_rts' => 'true',
'tweet_mode' => 'extended',
'count' => $numitems,
);
$connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
$tweets = $connection->get('statuses/user_timeline', $args);
if (!empty($tweets)) {
foreach ($tweets as $tweet) {
$text = $tweet->full_text;
// etcetera
Yes, you can use tweet_mode with the statuses/user_timeline API. Retweets are a special case, though. Check the retweeted_status object, as described at https://dev.to/kehers/formatting-tweets-a-look-at-extended-tweets-retweets-and-quotes-n5j
In short, if a tweet is a retweet, the extended tweet must be accessed at $tweet->retweeted_status->full_text. Thus, it's necessary in your code to check if each tweet object has a retweeted_status property.
