Is there any efforts on providing a Certbot DNS Plugin (https://certbot.eff.org/docs/using.html?highlight=dns#dns-plugins) leveraging your API?
That would ease issuing Letsencrypt wildcard certificates!
There are several examples at https://github.com/certbot/certbot.
There are some more hints at https://certbot.eff.org/docs/contributing.html#dev-plugin on how to accomplish that.
Hi kwin,
Thank you for your message, and welcome to deSEC! 
There is a certbot plugin draft here: https://github.com/akararsse/certbot-dns-desec
Unfortunately, I have not gotten around to review it. You are very welcome to fork it and do so!
Stay secure,
Peter
The hook script is now deprecated and the deSEC certbot plugin has been released. To request certificates from Let’s Encrypt for deSEC-hosted domains, please use the certbot plugin.
