 # How to use DNS API
 
+If your dns provider doesn't provide api access, you can use our dns alias mode:

 ## 17. Use Domain-Offensive/Resellerinterface/Domainrobot API
 
+ATTENTION: You need to be a registered Reseller to be able to use the ResellerInterface. As a normal user you can not use this method.
+
 You will need your login credentials (Partner ID+Password) to the Resellerinterface, and export them before you run `acme.sh`:

-for API username and token.
+Create your API token here: https://www.name.com/account/settings/api

+Note: `Namecom_Username` should be your Name.com username and not the token name.  If you accidentally run the script with the token name as the username see `~/.acme.sh/account.conf` to fix the issue

-## 42. Use All-inkl Kasserver API
+## 42. Use KingHost DNS API
+
+API access must be enabled at https://painel.kinghost.com.br/painel.api.php
+

+
+First, get your API key at https://my.zilore.com/account/api
+
+```
+export Zilore_Key="5dcad3a2-36cb-50e8-cb92-000002f9"

+## 44. Use Loopia.se API
+User must provide login credentials to the Loopia API.
+The user needs the following permissions:
+
+- addSubdomain
+- updateZoneRecord
+- getDomains
+- removeSubdomain
+
+Set the login credentials:
+```
+export LOOPIA_User="user@loopiaapi"
+export LOOPIA_Password="password"
+```
+
+And to issue a cert:
+```
+acme.sh --issue --dns dns_loopia -d example.com -d *.example.com
+```
+
+The username and password will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
+## 45. Use ACME DNS API
+
+ACME DNS is a limited DNS server with RESTful HTTP API to handle ACME DNS challenges easily and securely. 
+https://github.com/joohoi/acme-dns
+
+```
+export ACMEDNS_UPDATE_URL="https://auth.acme-dns.io/update"

+```
+
+The credentials will be saved in `~/.acme.sh/account.conf` and will
+be reused when needed.
+## 46. Use TELE3 API
+
+First you need to login to your TELE3 account to set your API-KEY.
+https://www.tele3.cz/system-acme-api.html
+
+```
+export TELE3_Key="MS2I4uPPaI..."
+export TELE3_Secret="kjhOIHGJKHg"

+
+The TELE3_Key and TELE3_Secret will be saved in ~/.acme.sh/account.conf and will be reused when needed.
