Introduction
cURL is a command-line program used by your server to exchange data with other websites and APIs. Since cURL supports secure protocols like HTTPS, it is essential for the safe transfer of sensitive information. Most Woosa plugins rely on cURL to connect your WooCommerce store to external platforms.
The cURL version is defined at the server level, meaning it is managed by your hosting provider.
Problem
You will need this article if:
You receive a notification in the WooCommerce backend stating that your cURL version is outdated.
You encounter SSL or connection errors (such as cURL error 35 or 52).
External API connections (e.g., bol.com, Amazon) are not working correctly because they require a minimum cURL version for security.
How to solve
Because cURL is installed on the server itself, only your hosting provider can update it.
Steps to take:
Check your current version: You can often find your cURL version in WordPress under 'Tools' > 'Site Health' > 'Info' > 'Server'.
Contact your hosting provider: Send a request to your host to update cURL to the latest stable version.
Use this sample message:
"Dear hosting provider,
I am using several WooCommerce plugins that require an up-to-date cURL version to securely connect to external APIs. Currently, my server is running an outdated version.
Could you please update the cURL version (and libcurl) on my server to the latest stable version? This is required for the API protocols my webshop uses.
I look forward to your confirmation."
