LetEncrypt Install Certificate

Use the LetEncrypt Install Certificate API to install the certificate issued by Let’s Encrypt. Let's Encrypt is a free, automated, and open Certificate Authority (CA). It will issue certificate for your domain names for free after domain name verification and Virtualizor from version 2.8.8 onward has integrated this feature.

The API response will contain "done" as the message "Configuration saved successfully" after the certificate is installed successfully.

For more information, you can refer this Let's Encrypt Certificate Installation Guide.
