TLS 1.2 & HTTP/1.1 Integration For PayPal

For your site to continue to be able to communicate with PayPal, you need to set your version of cURL to explicitly use the TLS 1.2 protocol. Setting this version prior to PayPal’s TLS 1.2 rollout should not impact current communications with PayPal. Here’s a code gist for setting the SSLVERSION for cURL that we will continue to develop and improve over time. Copy this code into your active theme’s [login to view URL] file or a custom plugin. /* Update the SSLVERSION for CURL to support PayPal Express moving to TLS 1.2 More info: [login to view URL] Your server will need to be updated to a supported version of OpenSSL for this to work. Add this code to your active theme's [login to view URL] or a custom plugin. */ function my_http_api_curl($handle) { curl_setopt( $handle, CURLOPT_SSLVERSION, 6 ); } add_action('http_api_curl', 'my_http_api_curl');
