+## 32. Use UnoEuro API to automatically issue cert
+
+First you need to login to your UnoEuro account to get your API key.
+
+```
+export UNO_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
+export UNO_User="UExxxxxx"
+```
+
+Ok, let's issue a cert now:
+```
+acme.sh --issue --dns dns_unoeuro -d example.com -d www.example.com
+```
+
+The `UNO_Key` and `UNO_User` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+
+## 33. Use INWX
+
+[INWX](https://www.inwx.de/) offers an [xmlrpc api](https://www.inwx.de/de/help/apidoc)  with your standard login credentials, set them like so:
+
+```
+export INWX_User="yourusername"
+export INWX_Password="password"
+```
+
+Then you can issue your certificates with:
+
+```
+acme.sh --issue --dns dns_inwx -d example.com -d www.example.com
+```
+
+The `INWX_User` and `INWX_Password` settings will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
