We will be changing the PrintUI servers to reject all SSLv3 traffic as of Monday, October 27th. If you are making API calls to the PrintUI servers where you are explicitly specifying that SSLv3 is to be used, you must change your code prior to that date. Note that some of the sample code that you may have downloaded from PrintUI does contain an explicit request to use SSLv3. Please delete any line from the sample code that looks like this:
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
