PHP Based Platforms
Connecting WordPress, OpenCart, Magento, or directly via the SDK
Connecting a PHP-based system requires that PHP 5.4+ is installed, but 5.6+ is preferred for stronger HTTPS security when communicating with our servers.
It's mandatory that the PHP function stream_socket_client is allowed by your host. This function is needed to establish the connection between your server and ours. It's used when communicating with our API. It's also recommended that the option allow_url_fopen is enabled.
Outbound connections to api.getnitropack.com must be allowed on port 443.
Summary:
PHP version 5.4+
stream_socket_client must be allowed
allow_url_fopen must be enabled
outbound connections to api.getnitropack.com must be allowed on port 443
These are basic network requirements covered by most web hosting solutions. If your server has some of these missing, feel free to reach out to your hosting provider or server admin and ask them to help you with the configuration.
