LetsEncrypt Renew CRT

You can manually renew already issued certificate for your domain by using the LetsEncrypt Renew CRT API. If the certificate renew day has not arrived, the renew request will be skipped if you have not set "force" option in configuration during installation of the certificate. The API response will contain "done" as the "actid" on successful start of the renewal process. This "actid" can used to monitor the process using the Show Tasks API, or you can check the progress the at Task module in the admin panel.

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