How to update the cURL version?

If you have an outdated cURL version, you may get a notification in the backend of WooCommerce. The cURL version is defined at the server level, or in other words through your hosting provider.

What is cURL?

CURL is a command-line program for obtaining or sending files and data.
Since cURL uses libcurl, it supports a range of commonly used Internet protocols, including (currently) HTTP, HTTPS, FTP, FTPS, SCP, SFTP, TFTP, LDAP, DAP, DICT, TELNET, FILE, IMAP, POP3, SMTP, and RTSP (the last four only in versions newer than 7.20.0 or February 9, 2010).
CURL supports HTTPS and performs SSL certificate verification by default when a secure protocol such as HTTPS is specified. When cURL connects to a remote server over HTTPS, it will obtain the remote server's certificate and then compare the validity of the remote server against its CA certificate to ensure that the remote server is the server it claims to be.
cURL is used by many API connections, since privacy sensitive information is shared over an HTTPS connection. Therefore, many of our plugins also require a minimum cURL version.

How to update a cURL version?

The cURL version can only be updated by your hosting provider. Please indicate clearly in this request that it is a cURL update related to a protocol of an API link.
