How to create a Plesk XML API access token and how to use it for XML API passwordless authentication?

Connect to the server via SSH

Specify the IP address and description that will be linked to this secret key and its description:

# plesk bin secret_key -c -ip-address 203.0.113.2 -description "Admin access token"
778a476a-cf1c-7434-ea47-9f229d70e934

Note: you may specify a few Ip addresses devided by comma.

Afterward, the Plesk secret key can be used placing it on the HTTP header request with the KEY parameter:

Note: Where 778a476a-cf1c-7434-ea47-9f229d70e934 is the admin access token, the api.rpc is a file containing the XML request and 203.0.113.10 is the Plesk server IP address

# curl -kLi -H "Content-Type: text/xml" -H "KEY: 778a476a-cf1c-7434-ea47-9f229d70e934" -H "HTTP_PRETTY_PRINT: TRUE" -d @api.rpc https://203.0.113.10:8443/enterprise/control/agent.php

Create a secret key for the Plesk administrator account by following the steps described above

Create the file api.rpc with the following content:

Note: Where 203.0.113.2 is the IP allowed for the connection and the login jdoe is the Plesk user

CONFIG_TEXT: <packet>
<secret_key>
<create>
<ip_address>203.0.113.2</ip_address>
<login>jdoe</login>
</create>
</secret_key>
</packet>

Send the API request:

Note: Where 778a476a-cf1c-7434-ea47-9f229d70e934 is the admin access token, the api.rpc is a file containing the XML request created on the previous step and 203.0.113.10 is the Plesk server IP address

# curl -kLi -H "Content-Type: text/xml" -H "KEY: 778a476a-cf1c-7434-ea47-9f229d70e934" -H "HTTP_PRETTY_PRINT: TRUE" -d @api.rpc https://203.0.113.10:8443/enterprise/control/agent.php

The API response will provide the access token belonging to the Plesk user:

CONFIG_TEXT: <?xml version="1.0" encoding="UTF-8"?>
<packet version="1.6.9.1">
<secret_key>
<create>
<result>
<status>ok</status>
<key>e4b01d73-7368-64a6-0515-9fa8fc1d3a78</key>
</result>
</create>
</secret_key>
</packet>

Afterward, the secret key belonging to the Plesk user can be used for Plesk XML API requests:

Note: Where e4b01d73-7368-64a6-0515-9fa8fc1d3a78 is the Plesk user access token, the api.rpc is a file containing the XML request and 203.0.113.10 is the Plesk server IP address

# curl -kLi -H "Content-Type: text/xml" -H "KEY: e4b01d73-7368-64a6-0515-9fa8fc1d3a78" -H "HTTP_PRETTY_PRINT: TRUE" -d @api.rpc https://203.0.113.10:8443/enterprise/control/agent.php
