SSLv3 support for API will be disabled on Erply servers. This means some customer integrations using SSLv3 protocol may get broken and should be fixed. Please inspect your webshops and other API integrations and remove SSLv3 parameters from curl configurations.
For example if you are using an old EAPI.class.php for your integration this can be done by downloading the updated class from ERPLY home page https://erply.com/files_shared/EAPI.class.php.zip (renewed Nov 2016). Or by commenting out curl_setopt($handle, CURLOPT_SSLVERSION,3) line in the existing EAPI.class.php file.
This information should be sent to your developer. If you have any questions please contact firstname.lastname@example.org
