 # Using deploy api
 
-Before you can deploy your cert, you must [issue the cert first](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert).
+deploy hook usage:
 
-Here are the scripts to deploy the certs/key to the server/services.
+https://github.com/Neilpang/acme.sh/wiki/deployhooks
 
-## 1. Deploy the certs to your cpanel host
-
-If you want to deploy using cpanel UAPI see 7.
-
-(cpanel deploy hook is not finished yet, this is just an example.)
-
-
-
-Then you can deploy now:
-
-```sh
-export DEPLOY_CPANEL_USER=myusername
-export DEPLOY_CPANEL_PASSWORD=PASSWORD
-acme.sh --deploy -d example.com --deploy-hook cpanel
-```
-
-## 2. Deploy ssl cert on kong proxy engine based on api
-
-Before you can deploy your cert, you must [issue the cert first](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert).
-Currently supports Kong-v0.10.x.
-
-```sh
-acme.sh --deploy -d ftp.example.com --deploy-hook kong
-```
-
-## 3. Deploy the cert to remote server through SSH access
-
-The ssh deploy plugin allows you to deploy certificates to a remote host
-using SSH command to connect to the remote server.  The ssh plugin is invoked
-with the following command...
-
-```sh
-acme.sh --deploy -d example.com --deploy-hook ssh
-```
-Prior to running this for the first time you must tell the plugin where
-and how to deploy the certificates.  This is done by exporting the following
-environment variables.  This is not required for subsequent runs as the
-values are stored by acme.sh in the domain configuration files.
-
-Required...
-```
-export DEPLOY_SSH_USER=username
-```
-Optional...
-```
-export DEPLOY_SSH_CMD=custom ssh command
-export DEPLOY_SSH_SERVER=url or ip address of remote host
-export DEPLOY_SSH_KEYFILE=filename for private key
-export DEPLOY_SSH_CERTFILE=filename for certificate file
-export DEPLOY_SSH_CAFILE=filename for intermediate CA file
-export DEPLOY_SSH_FULLCHAIN=filename for fullchain file
-export DEPLOY_SSH_REMOTE_CMD=command to execute on remote host
-export DEPLOY_SSH_BACKUP=yes or no
-```
-
-**DEPLOY_SSH_USER**
-Username at the remote host that SSH will login with. Note that
-SSH must be able to login to remote host without a password... SSH Keys
-must have been exchanged with the remote host. Validate and test that you
-can login to USER@URL from the host running acme.sh before using this script.
-
-The USER@URL at the remote server must also have has permissions to write to
-the target location of the certificate files and to execute any commands
-(e.g. to stop/start services).
-
-**DEPLOY_SSH_CMD**
-You can customize the ssh command used to connect to the remote host. For example
-if you need to connect to a specific port at the remote server you can set this
-to, for example, "ssh -p 22" or to use `sshpass` to provide password inline
-instead of exchanging ssh keys (this is not recommended, using keys is
-more secure).
-
-**DEPLOY_SSH_SERVER**
-URL or IP Address of the remote server.  If not provided then the domain
-name provided on the acme.sh --deploy command line is used.
-
-**DEPLOY_SSH_KEYFILE**
-Target filename for the private key issued by LetsEncrypt.
-
-**DEPLOY_SSH_CERTFILE**
-Target filename for the certificate issued by LetsEncrypt.
-If this is the same as the previous filename (for keyfile) then it is
-appended to the same file.
-
-**DEPLOY_SSH_CAFILE**
-Target filename for the CA intermediate certificate issued by LetsEncrypt.
-If this is the same as a previous filename (for keyfile or certfile) then
-it is appended to the same file.
-
-**DEPLOY_SSH_FULLCHAIN**
-Target filename for the fullchain certificate issued by LetsEncrypt.
-If this is the same as a previous filename (for keyfile, certfile or
-cafile) then it is appended to the same file.
-
-**DEPLOY_SSH_REMOTE_CMD**
-Command to execute on the remote server after copying any certificates.  This
-could be any additional command required for example to stop and restart
-the service.
-
-**DEPLOY_SSH_BACKUP**
-Before writing a certificate file to the remote server the existing
-certificate will be copied to a backup directory on the remote server.
-These are placed in a hidden directory in the home directory of the SSH
-user
-```sh
-~/.acme_ssh_deploy/[domain name]-backup-[timestamp]
-```
-Any backups older than 180 days will be deleted when new certificates
-are deployed.  This defaults to "yes" set to "no" to disable backup.
-
-###Examples using SSH deploy
-The following example illustrates deploying certificates to a QNAP NAS
-(tested with QTS version 4.2.3)
-
-```sh
-export DEPLOY_SSH_USER="admin"
-export DEPLOY_SSH_KEYFILE="/etc/stunnel/stunnel.pem"
-export DEPLOY_SSH_CERTFILE="/etc/stunnel/stunnel.pem"
-export DEPLOY_SSH_CAFILE="/etc/stunnel/uca.pem"
-export DEPLOY_SSH_REMOTE_CMD="/etc/init.d/stunnel.sh restart"
-
-acme.sh --deploy -d qnap.example.com --deploy-hook ssh
-```
-Note how in this example both the private key and certificate point to
-the same file.  This will result in the certificate being appended
-to the same file as the private key... a common requirement of several
-services.
-
-The next example illustrates deploying certificates to a Unifi
-Controller (tested with version 5.4.11).
-
-```sh
-export DEPLOY_SSH_USER="root"
-export DEPLOY_SSH_KEYFILE="/var/lib/unifi/unifi.example.com.key"
-export DEPLOY_SSH_FULLCHAIN="/var/lib/unifi/unifi.example.com.cer"
-export DEPLOY_SSH_REMOTE_CMD="openssl pkcs12 -export \
-   -inkey /var/lib/unifi/unifi.example.com.key \
-   -in /var/lib/unifi/unifi.example.com.cer \
-   -out /var/lib/unifi/unifi.example.com.p12 \
-   -name ubnt -password pass:temppass \
- && keytool -importkeystore -deststorepass aircontrolenterprise \
-   -destkeypass aircontrolenterprise \
-   -destkeystore /var/lib/unifi/keystore \
-   -srckeystore /var/lib/unifi/unifi.example.com.p12 \
-   -srcstoretype PKCS12 -srcstorepass temppass -alias ubnt -noprompt \
- && service unifi restart"
-
-acme.sh --deploy -d unifi.example.com --deploy-hook ssh
-```
-In this example we execute several commands on the remote host
-after the certificate files have been copied... to generate a pkcs12 file
-compatible with Unifi, to import it into the Unifi keystore and then finally
-to restart the service.
-
-Note also that once the certificate is imported
-into the keystore the individual certificate files are no longer
-required. We could if we desired delete those files immediately. If we
-do that then we should disable backup at the remote host (as there are
-no files to backup -- they were erased during deployment). For example...
-```sh
-export DEPLOY_SSH_BACKUP=no
-# modify the end of the remote command...
-&& rm /var/lib/unifi/unifi.example.com.key \
-      /var/lib/unifi/unifi.example.com.cer \
-      /var/lib/unifi/unifi.example.com.p12 \
-&& service unifi restart
-```
-
-## 4. Deploy the cert to local vsftpd server
-
-```sh
-acme.sh --deploy -d ftp.example.com --deploy-hook vsftpd
-```
-
-The default vsftpd conf file is `/etc/vsftpd.conf`,  if your vsftpd conf is not in the default location, you can specify one:
-
-```sh
-export DEPLOY_VSFTPD_CONF="/etc/vsftpd.conf"
-
-acme.sh --deploy -d ftp.example.com --deploy-hook vsftpd
-```
-
-The default command to restart vsftpd server is `service vsftpd restart`, if it doesn't work, you can specify one:
-
-```sh
-export DEPLOY_VSFTPD_RELOAD="/etc/init.d/vsftpd restart"
-
-acme.sh --deploy -d ftp.example.com --deploy-hook vsftpd
-```
-
-## 5. Deploy the cert to local exim4 server
-
-```sh
-acme.sh --deploy -d ftp.example.com --deploy-hook exim4
-```
-
-The default exim4 conf file is `/etc/exim/exim.conf`,  if your exim4 conf is not in the default location, you can specify one:
-
-```sh
-export DEPLOY_EXIM4_CONF="/etc/exim4/exim4.conf.template"
-
-acme.sh --deploy -d ftp.example.com --deploy-hook exim4
-```
-
-The default command to restart exim4 server is `service exim4 restart`, if it doesn't work, you can specify one:
-
-```sh
-export DEPLOY_EXIM4_RELOAD="/etc/init.d/exim4 restart"
-
-acme.sh --deploy -d ftp.example.com --deploy-hook exim4
-```
-
-## 6. Deploy the cert to OSX Keychain
-
-```sh
-acme.sh --deploy -d ftp.example.com --deploy-hook keychain
-```
-
-## 7. Deploy to cpanel host using UAPI
-
-This hook is using UAPI and works in cPanel & WHM version 56 or newer.
-```
-acme.sh  --deploy  -d example.com  --deploy-hook cpanel_uapi
-```
-DEPLOY_CPANEL_USER is required only if you run the script as root and it should contain cpanel username.
-```sh
-export DEPLOY_CPANEL_USER=username
-acme.sh  --deploy  -d example.com  --deploy-hook cpanel_uapi
-```
-Please note, that the cpanel_uapi hook will deploy only the first domain when your certificate will automatically renew. Therefore you should issue a separate certificate for each domain. 
-
-## 8. Deploy the cert to your FRITZ!Box router
-
-You must specify the credentials that have administrative privileges on the FRITZ!Box in order to deploy the certificate, plus the URL of your FRITZ!Box, through the following environment variables:
-```sh
-$ export DEPLOY_FRITZBOX_USERNAME=my_username
-$ export DEPLOY_FRITZBOX_PASSWORD=the_password
-$ export DEPLOY_FRITZBOX_URL=https://fritzbox.example.com
-```
-
-After the first deployment, these values will be stored in your $HOME/.acme.sh/account.conf. You may now deploy the certificate like this:
-
-```sh
-acme.sh --deploy -d fritzbox.example.com --deploy-hook fritzbox
-```
-
-## 9. Deploy the cert to strongswan
-
-```sh
-acme.sh --deploy -d ftp.example.com --deploy-hook strongswan
-```
-
-## 10. Deploy the cert to HAProxy
-
-You must specify the path where you want the concatenated key and certificate chain written.
-```sh
-export DEPLOY_HAPROXY_PEM_PATH=/etc/haproxy
-```
-
-You may optionally define the command to reload HAProxy. The value shown below will be used as the default if you don't set this environment variable.
-
-```sh
-export DEPLOY_HAPROXY_RELOAD="/usr/sbin/service haproxy restart"
-```
-
-You can then deploy the certificate as follows
-```sh
-acme.sh --deploy -d haproxy.example.com --deploy-hook haproxy
-```
-
-The path for the PEM file will be stored with the domain configuration and will be available when renewing, so that deploy will happen automatically when renewed.
-
-## 11. Deploy your cert to Gitlab pages
-
-You must define the API key and the informations for the project and Gitlab page you are updating the certificate for.
-
-```sh
-# The token can be created in your user settings under "Access Tokens"
-export GITLAB_TOKEN="xxxxxxxxxxx"
-
-# The project ID is displayed on the home page of the project
-export GITLAB_PROJECT_ID=12345678
-
-# The domain must match the one defined for the Gitlab page, without "https://"
-export GITLAB_DOMAIN="www.mydomain.com"
-```
-
-You can then deploy the certificate as follows
-
-```sh
-acme.sh --deploy -d www.mydomain.com --deploy-hook gitlab
-```
-
-## 12. Deploy your cert to Hashicorp Vault
-
-```sh
-export VAULT_PREFIX="acme"
-```
-
-You can then deploy the certificate as follows
-
-```sh
-acme.sh --deploy -d www.mydomain.com --deploy-hook vault_cli
-```
-
-Your certs will be saved in Vault using this structure:
-
-```sh
-vault write "${VAULT_PREFIX}/${domain}/cert.pem"      value=@"..."
-vault write "${VAULT_PREFIX}/${domain}/cert.key"      value=@"..."
-vault write "${VAULT_PREFIX}/${domain}/chain.pem"     value=@"..."
-vault write "${VAULT_PREFIX}/${domain}/fullchain.pem" value=@"..."
-```
-
-You might be using Fabio load balancer (which can get certs from
-Vault). It needs a bit different structure of your certs in Vault. It
-gets certs only from keys that were saved in `prefix/domain`, like this:
-
-```bash
-vault write <PREFIX>/www.domain.com cert=@cert.pem key=@key.pem
-```
-
-If you want to save certs in Vault this way just set "FABIO" env
-variable to anything (ex: "1") before running `acme.sh`:
-
-```sh
-export FABIO="1"
-```
-
-## 13. Deploy your certificate to Qiniu.com
-
-使用 acme.sh 部署到七牛之前，需要确保部署的域名已打开 HTTPS 功能，您可以访问[融合 CDN - 域名管理](https://portal.qiniu.com/cdn/domain) 设置。
-另外还需要先导出 AK/SK 环境变量，您可以访问[密钥管理](https://portal.qiniu.com/user/key) 获得。
-
-```sh
-$ export QINIU_AK="foo"
-$ export QINIU_SK="bar"
-```
-
-完成准备工作之后，您就可以通过下面的命令开始部署 SSL 证书到七牛上：
-
-```sh
-$ acme.sh --deploy -d example.com --deploy-hook qiniu
-```
-
-假如您部署的证书为泛域名证书，您还需要设置 `QINIU_CDN_DOMAIN` 变量，指定实际需要部署的域名(请注意泛域名前的点)：
-
-```sh
-$ export QINIU_CDN_DOMAIN=".cdn.example.com"
-$ acme.sh --deploy -d example.com --deploy-hook qiniu
-```
-
-### English version
-
-You should create AccessKey/SecretKey pair in https://portal.qiniu.com/user/key 
-before deploying your certificate, and please ensure you have enabled HTTPS for
-your domain name. You can enable it in https://portal.qiniu.com/cdn/domain.
-
-```sh
-$ export QINIU_AK="foo"
-$ export QINIU_SK="bar"
-```
-
-then you can deploy certificate by following command:
-
-```sh
-$ acme.sh --deploy -d example.com --deploy-hook qiniu
-```
-
-(Optional), If you are using wildcard certificate,
-you may need export `QINIU_CDN_DOMAIN` to specify which domain
-you want to update (please note the leading dot):
-
-```sh
-$ export QINIU_CDN_DOMAIN=".cdn.example.com"
-$ acme.sh --deploy -d example.com --deploy-hook qiniu
-```
-
-## 14. Deploy your cert on MyDevil.net
-
-Once you have acme.sh installed and certificate issued (see info in [DNS API](../dnsapi/README.md#61-use-mydevilnet)), you can install it by following command:
-
-```sh
-acme.sh --deploy --deploy-hook mydevil -d example.com
-```
-
-That will remove old certificate and install new one.

 # How to use DNS API
+DNS api usage:
 
-If your dns provider doesn't provide api access, you can use our dns alias mode:
-
-https://github.com/Neilpang/acme.sh/wiki/DNS-alias-mode
-
-## 1. Use CloudFlare domain API to automatically issue cert
-
-First you need to login to your CloudFlare account to get your [API key](https://dash.cloudflare.com/profile). 
-
-```
-export CF_Key="sdfsdfsdfljlbjkljlkjsdfoiwje"
-export CF_Email="xxxx@sss.com"
-```
-
-Ok, let's issue a cert now:
-```
-acme.sh --issue --dns dns_cf -d example.com -d www.example.com
-```
-
-The `CF_Key` and `CF_Email` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
-
-

-
-```
-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.

-```
-
-The `AD_API_KEY` will be saved in `~/.acme.sh/account.conf` and will be reused
-when needed.
-
-## 14. Use Linode domain API
-
-The tokens created in the classic manager and cloud manager are incompatible
-with one another. While the classic manager makes an all or nothing API, the
-newer cloud manager interface promises to produce API keys with a finer
-permission system. However, either way works just fine.
-
-### Classic Manager ###
-
-Classic Manager: https://manager.linode.com/profile/api
-
-First you need to login to your Linode account to get your API Key.
-
-Then add an API key with label *ACME* and copy the new key into the following
-command.
-
-```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.
-
-### Cloud Manager ###
-
-Cloud Manager: https://cloud.linode.com/profile/tokens
-
-First you need to login to your Linode account to get your API Key.
-
-   1. Click on "Add a Personal Access Token".
-   2. Give the new key a "Label" (we recommend *ACME*)
-   3. Give it Read/Write access to "Domains"
-   4. "Submit" and copy the new key into the `LINODE_V4_API_KEY` command below.
-
-```sh
-export LINODE_V4_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_v4 --dnssleep 900 -d example.com -d www.example.com
-```
-
-The `LINODE_V4_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

-```
-
-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/).
-
-```
-export 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"

-```
-
-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.

-```
-
-## 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.

-
-## 49. Use Google Cloud DNS API to automatically issue cert
-
-First you need to authenticate to gcloud.
-
-```
-gcloud init
-```
-
-**The `dns_gcloud` script uses the active gcloud configuration and credentials.**
-There is no logic inside `dns_gcloud` to override the project and other settings.
-If needed, create additional [gcloud configurations](https://cloud.google.com/sdk/gcloud/reference/topic/configurations).
-You can change the configuration being used without *activating* it; simply set the `CLOUDSDK_ACTIVE_CONFIG_NAME` environment variable.
-
-To issue a certificate you can:
-```
-export CLOUDSDK_ACTIVE_CONFIG_NAME=default  # see the note above
-acme.sh --issue --dns dns_gcloud -d example.com -d '*.example.com'

-```
-
-Now, let's issue a cert:
-```
-acme.sh --issue --dns dns_netcup -d example.com -d www.example.com
-```
-
-The `NC_Apikey`,`NC_Apipw` and `NC_CID` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
-## 52. Use GratisDNS.dk
-
-GratisDNS.dk (https://gratisdns.dk/) 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 GratisDNS website to read the HTML and posting updates as HTTP.  The plugin needs to know your
-userid and password for the GratisDNS website.
-
-```sh
-export GDNSDK_Username="..."
-export GDNSDK_Password="..."
-```
-The username and password will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
-
-
-Now you can issue a certificate.
-
-Note: It usually takes a few minutes (usually 3-4 minutes) before the changes propagates to gratisdns.dk nameservers (ns3.gratisdns.dk often are slow),
-and in rare cases I have seen over 5 minutes before google DNS catches it. Therefor a DNS sleep of at least 300 seconds are recommended-
-
-```sh
-acme.sh --issue --dns dns_gdnsdk --dnssleep 300 -d example.com -d *.example.com
-```
-
-## 53. Use Namecheap
-
-You will need your namecheap username, API KEY (https://www.namecheap.com/support/api/intro.aspx) and your external IP address (or an URL to get it), this IP will need to be whitelisted at Namecheap.
-Due to Namecheap's API limitation all the records of your domain will be read and re applied, make sure to have a backup of your records you could apply if any issue would arise.
-
-```sh
-export NAMECHEAP_USERNAME="..."
-export NAMECHEAP_API_KEY="..."
-export NAMECHEAP_SOURCEIP="..."
-```
-
-NAMECHEAP_SOURCEIP can either be an IP address or an URL to provide it (e.g. https://ifconfig.co/ip).
-
-The username and password will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
-
-Now you can issue a certificate.
-
-```sh
-acme.sh --issue --dns dns_namecheap -d example.com -d *.example.com

-```
-acme.sh --issue --dns dns_mydnsjp -d example.com -d www.example.com
-```
-The `MYDNSJP_MasterID` and `MYDNSJP_Password` will be saved in `~/.acme.sh/account.conf` and will be reused when needed.
-
-## 55. Use hosting.de API

-
-```
-export HOSTINGDE_APIKEY='xxx'
-export HOSTINGDE_ENDPOINT='https://secure.hosting.de'
-```
-
-The plugin can also be used for the http.net API. http.net customers have to set endpoint to https://partner.http.net.
-
-Ok, let's issue a cert now:
-```
-acme.sh --issue --dns dns_hostingde -d example.com -d *.example.com

-
-# 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
-```
-
-For more details, please check our sample script: [dns_myapi.sh](dns_myapi.sh)
