How can I install Twitter API SSL Root CA Certificate

  • Posted April 26, 2014

Hi, I’m having issues with my Twitter application on Digital Ocean and I found out (already tried on my local server XAMPP) that I need to install the Root CA Certificate (

I managed to easily do it on my local server but I can’t find out how to do it on my droplet here (I use LAMP on Ubuntu 12.04).

Any suggestions?

@diego: What is the actual error that you’re seeing? Why do you think the problem is with the certificate?

Ugh, I don’t get it. It’s not working. On my local server its working like a charm, but on my droplet no. Do you think its related to something on curl? <br>My code is this one, it returns nothing on $response: <br> <br>require_once(‘lib/TwitterAPIExchange.php’); <br>include “config.php”; <br> <br>$url = ‘’; <br>$getfield = ‘?q=porra&result_type=recent&count=100’; <br>$requestMethod = ‘GET’; <br>$twitter = new TwitterAPIExchange($settings); <br> <br>$response = $twitter->setGetfield($getfield) <br> ->buildOauth($url, $requestMethod) <br> ->performRequest();
<br> <br>

sudo wget -O /usr/lib/ssl/certs/cacert.pem
