## 7. Use nsupdate to automatically issue cert

First, generate a key for updating the zone
```
b=$(dnssec-keygen -a hmac-sha512 -b 512 -n USER -K /tmp foo)
cat > /etc/named/keys/update.key <<EOF
key "update" {
    algorithm hmac-sha512;
    secret "$(awk '/^Key/{print $2}' /tmp/$b.private)";
};
EOF
rm -f /tmp/$b.{private,key}
```

Include this key in your named configuration
```
include "/etc/named/keys/update.key";
```

Next, configure your zone to allow dynamic updates.

Depending on your named version, use either
```
zone "example.com" {
    type master;
    allow-update { key "update"; };
};
```
or
```
zone "example.com" {
    type master;
    update-policy {
        grant update subdomain example.com.;
    };
}
```

Finally, make the DNS server and update Key available to `acme.sh`

```
export NSUPDATE_SERVER="dns.example.com"
export NSUPDATE_KEY="/path/to/your/nsupdate.key"
```

Ok, let's issue a cert now:

```

The `ME_Key` and `ME_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.


## 10. Use Amazon Route53 domain API

https://github.com/Neilpang/acme.sh/wiki/How-to-use-Amazon-Route53-API

```
export  AWS_ACCESS_KEY_ID=XXXXXXXXXX
export  AWS_SECRET_ACCESS_KEY=XXXXXXXXXXXXXXX

```

The `Ali_Key` and `Ali_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 12. Use ISPConfig 3.1 API

This only works for ISPConfig 3.1 (and newer).

Create a Remote User in the ISPConfig Control Panel. The Remote User must have access to at least `DNS zone functions` and `DNS txt functions`.

```
export ISPC_User="xxx"
export ISPC_Password="xxx"
export ISPC_Api="https://ispc.domain.tld:8080/remote/json.php"
export ISPC_Api_Insecure=1
```
If you have installed ISPConfig on a different port, then alter the 8080 accordingly.
Leaver ISPC_Api_Insecure set to 1 if you have not a valid ssl cert for your installation. Change it to 0 if you have a valid ssl cert.

To issue a cert:
```
acme.sh --issue --dns dns_ispconfig -d example.com -d www.example.com
```

The `ISPC_User`, `ISPC_Password`, `ISPC_Api`and `ISPC_Api_Insecure` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 13. Use Alwaysdata domain API

First you need to login to your Alwaysdata account to get your API Key.

```sh
export AD_API_KEY="myalwaysdataapikey"
```

Ok, let's issue a cert now:

```sh
acme.sh --issue --dns dns_ad -d example.com -d www.example.com
```

The `AD_API_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused
when needed.

## 14. Use Linode domain API

First you need to login to your Linode account to get your API Key.
[https://manager.linode.com/profile/api](https://manager.linode.com/profile/api)

Then add an API key with label *ACME* and copy the new key.

```sh
export LINODE_API_KEY="..."
```

Due to the reload time of any changes in the DNS records, we have to use the `dnssleep` option to wait at least 15 minutes for the changes to take effect.

Ok, let's issue a cert now:

```sh
acme.sh --issue --dns dns_linode --dnssleep 900 -d example.com -d www.example.com
```

The `LINODE_API_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 15. Use FreeDNS

FreeDNS (https://freedns.afraid.org/) does not provide an API to update DNS records (other than IPv4 and IPv6
dynamic DNS addresses).  The acme.sh plugin therefore retrieves and updates domain TXT records by logging
into the FreeDNS website to read the HTML and posting updates as HTTP.  The plugin needs to know your
userid and password for the FreeDNS website.

```sh
export FREEDNS_User="..."
export FREEDNS_Password="..."
```

You need only provide this the first time you run the acme.sh client with FreeDNS validation and then again
whenever you change your password at the FreeDNS site.  The acme.sh FreeDNS plugin does not store your userid
or password but rather saves an authentication token returned by FreeDNS in `~/.acme.sh/account.conf` and
reuses that when needed.

Now you can issue a certificate.

```sh
acme.sh --issue --dns dns_freedns -d example.com -d www.example.com
```

Note that you cannot use acme.sh automatic DNS validation for FreeDNS public domains or for a subdomain that
you create under a FreeDNS public domain.  You must own the top level domain in order to automatically
validate with acme.sh at FreeDNS.

## 16. Use cyon.ch

You only need to set your cyon.ch login credentials.
If you also have 2 Factor Authentication (OTP) enabled, you need to set your secret token too and have `oathtool` installed.

```
export CY_Username="your_cyon_username"
export CY_Password="your_cyon_password"
export CY_OTP_Secret="your_otp_secret" # Only required if using 2FA
```

To issue a cert:
```
acme.sh --issue --dns dns_cyon -d example.com -d www.example.com
```

The `CY_Username`, `CY_Password` and `CY_OTP_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 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`:
```
export DO_PID="KD-1234567"
export DO_PW="cdfkjl3n2"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_do -d example.com -d www.example.com
```

## 18. Use Gandi LiveDNS API

You must enable the new Gandi LiveDNS API first and the create your api key, See: http://doc.livedns.gandi.net/

```
export GANDI_LIVEDNS_KEY="fdmlfsdklmfdkmqsdfk"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_gandi_livedns -d example.com -d www.example.com
```

## 19. Use Knot (knsupdate) DNS API to automatically issue cert

First, generate a TSIG key for updating the zone.

```
keymgr tsig generate -t acme_key hmac-sha512 > /etc/knot/acme.key
```

Include this key in your knot configuration file.

```
include: /etc/knot/acme.key
```

Next, configure your zone to allow dynamic updates.

Dynamic updates for the zone are allowed via proper ACL rule with the `update` action. For in-depth instructions, please see [Knot DNS's documentation](https://www.knot-dns.cz/documentation/).

```
acl:
  - id: acme_acl
    address: 192.168.1.0/24
    key: acme_key
    action: update

zone:
  - domain: example.com
    file: example.com.zone
    acl: acme_acl
```

Finally, make the DNS server and TSIG Key available to `acme.sh`

```
export KNOT_SERVER="dns.example.com"
export KNOT_KEY=`grep \# /etc/knot/acme.key | cut -d' ' -f2`
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_knot -d example.com -d www.example.com
```

The `KNOT_SERVER` and `KNOT_KEY` settings will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 20. Use DigitalOcean API (native)

You need to obtain a read and write capable API key from your DigitalOcean account. See: https://www.digitalocean.com/help/api/

```
export DO_API_KEY="75310dc4ca779ac39a19f6355db573b49ce92ae126553ebd61ac3a3ae34834cc"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_dgon -d example.com -d www.example.com
```

## 21. Use ClouDNS.net API

You need to set the HTTP API user ID and password credentials. See: https://www.cloudns.net/wiki/article/42/. For security reasons, it's recommended to use a sub user ID that only has access to the necessary zones, as a regular API user has access to your entire account.

```
# Use this for a sub auth ID
export CLOUDNS_SUB_AUTH_ID=XXXXX
# Use this for a regular auth ID
#export CLOUDNS_AUTH_ID=XXXXX
export CLOUDNS_AUTH_PASSWORD="YYYYYYYYY"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_cloudns -d example.com -d www.example.com
```
The `CLOUDNS_AUTH_ID` and `CLOUDNS_AUTH_PASSWORD` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 22. Use Infoblox API

First you need to create/obtain API credentials on your Infoblox appliance.

```
export Infoblox_Creds="username:password"
export Infoblox_Server="ip or fqdn of infoblox appliance"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_infoblox -d example.com -d www.example.com
```

Note: This script will automatically create and delete the ephemeral txt record.
The `Infoblox_Creds` and `Infoblox_Server` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.


## 23. Use VSCALE API

First you need to create/obtain API tokens on your [settings panel](https://vscale.io/panel/settings/tokens/).

```
VSCALE_API_KEY="sdfsdfsdfljlbjkljlkjsdfoiwje"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_vscale -d example.com -d www.example.com
```

##  24. Use Dynu API

First you need to create/obtain API credentials from your Dynu account. See: https://www.dynu.com/resources/api/documentation

```
export Dynu_ClientId="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
export Dynu_Secret="yyyyyyyyyyyyyyyyyyyyyyyyy"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_dynu -d example.com -d www.example.com
```

The `Dynu_ClientId` and `Dynu_Secret` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 25. Use DNSimple API

First you need to login to your DNSimple account and generate a new oauth token.

https://dnsimple.com/a/{your account id}/account/access_tokens

Note that this is an _account_ token and not a user token. The account token is
needed to infer the `account_id` used in requests. A user token will not be able
to determine the correct account to use.

```
export DNSimple_OAUTH_TOKEN="sdfsdfsdfljlbjkljlkjsdfoiwje"
```

To issue the cert just specify the `dns_dnsimple` API.

```
acme.sh --issue --dns dns_dnsimple -d example.com
```

The `DNSimple_OAUTH_TOKEN` will be saved in `~/.acme.sh/account.conf` and will
be reused when needed.

If you have any issues with this integration please report them to
https://github.com/pho3nixf1re/acme.sh/issues.

## 26. Use NS1.com API

```
export NS1_Key="fdmlfsdklmfdkmqsdfk"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_nsone -d example.com -d www.example.com
```

## 27. Use DuckDNS.org API

```
export DuckDNS_Token="aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee"
```

Please note that since DuckDNS uses StartSSL as their cert provider, thus
--insecure may need to be used when issuing certs:
```
acme.sh --insecure --issue --dns dns_duckdns -d mydomain.duckdns.org
```

For issues, please report to https://github.com/raidenii/acme.sh/issues.

## 28. Use Name.com API

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

```
export Namecom_Username="testuser"
export Namecom_Token="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
```

And now you can issue certs with:

```
acme.sh --issue --dns dns_namecom -d example.com -d www.example.com
```

For issues, please report to https://github.com/raidenii/acme.sh/issues.

## 29. Use Dyn Managed DNS API to automatically issue cert

First, login to your Dyn Managed DNS account: https://portal.dynect.net/login/

The minimum "Zones & Records Permissions" required are:
```
RecordAdd
RecordUpdate
RecordDelete
RecordGet
ZoneGet
ZoneAddNode
ZoneRemoveNode
ZonePublish
```

Pass the API user credentials to the environment:
```
export DYN_Customer="customer"
export DYN_Username="apiuser"
export DYN_Password="secret"
```

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_dyn -d example.com -d www.example.com
```

The `DYN_Customer`, `DYN_Username` and `DYN_Password` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 30. Use pdd.yandex.ru API

```
export PDD_Token="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
```

Follow these instructions to get the token for your domain https://tech.yandex.com/domain/doc/concepts/access-docpage/
```
acme.sh --issue --dns dns_yandex -d mydomain.example.org
```

For issues, please report to https://github.com/non7top/acme.sh/issues.

## 31. Use Hurricane Electric

Hurricane Electric (https://dns.he.net/) doesn't have an API so just set your login credentials like so:

```
export HE_Username="yourusername"
export HE_Password="password"
```

```

The `INWX_User` and `INWX_Password` settings will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 34. User Servercow API v1

Create a new user from the servercow control center. Don't forget to activate **DNS API** for this user.

```
export SERVERCOW_API_Username=username
export SERVERCOW_API_Password=password
```

Now you cann issue a cert:

```
acme.sh --issue --dns dns_servercow -d example.com -d www.example.com
```
Both, `SERVERCOW_API_Username` and `SERVERCOW_API_Password` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

```

The `AUTODNS_USER`, `AUTODNS_PASSWORD` and `AUTODNS_CONTEXT` settings will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 37. Use Azure DNS

You have to create a service principal first. See:[How to use Azure DNS](../../../wiki/How-to-use-Azure-DNS)

```
export AZUREDNS_SUBSCRIPTIONID="12345678-9abc-def0-1234-567890abcdef"
export AZUREDNS_TENANTID="11111111-2222-3333-4444-555555555555"
export AZUREDNS_APPID="3b5033b5-7a66-43a5-b3b9-a36b9e7c25ed"

```

The `ZM_Key` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 40. Use DreamHost DNS API

DNS API keys may be created at https://panel.dreamhost.com/?tree=home.api.
Ensure the created key has add and remove privelages.

```
export DH_API_Key="<api key>"
acme.sh --issue --dns dns_dreamhost -d example.com -d www.example.com
```

The 'DH_API_KEY' will be saved in `~/.acme.sh/account.conf` and will
be reused when needed.

## 41. Use DirectAdmin API
The DirectAdmin interface has it's own Let's encrypt functionality, but this
script can be used to generate certificates for names which are not hosted on
DirectAdmin

User must provide login data and URL to the DirectAdmin incl. port.
You can create an user which only has access to

- CMD_API_DNS_CONTROL
- CMD_API_SHOW_DOMAINS

By using the Login Keys function.
See also https://www.directadmin.com/api.php and https://www.directadmin.com/features.php?id=1298

```
export DA_Api="https://remoteUser:remotePassword@da.domain.tld:8443"
export DA_Api_Insecure=1
```
Set `DA_Api_Insecure` to 1 for insecure and 0 for secure -> difference is whether ssl cert is checked for validity (0) or whether it is just accepted (1)

Ok, let's issue a cert now:
```
acme.sh --issue --dns dns_da -d example.com -d www.example.com
```

The `DA_Api` and `DA_Api_Insecure` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

## 42. Use Zilore API to automatically issue cert

```
acme.sh --issue --dns dns_zilore -d example.com -d www.example.com
```

The `Zilore_Key` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.

# Use custom API

If your API is not supported yet, you can write your own DNS API.

Let's assume you want to name it 'myapi':

1. Create a bash script named `~/.acme.sh/dns_myapi.sh`,
2. In the script you must have a function named `dns_myapi_add()` which will be called by acme.sh to add the DNS records.
3. Then you can use your API to issue cert like this:

```
acme.sh --issue --dns dns_myapi -d example.com -d www.example.com
