Retrieving License Key
To retrieve the Plesk license key currently installed on a server, use the get operation with the key parameter specified.
A request XML packet getting license key contains the key node nested within the get operational node:
<packet>
<server>
<get>
<key/>
</get>
</server>
</packet>
An XML response packet received from the server can look as follows:
<packet version="1.6.7.0">
<server>
<get>
<result>
<status>ok</status>
<key>
<property>
<name>plesk_key_id</name>
<value>plsk.00000000.0000</value>
</property>
<property>
<name>product_version</name>
<value>12.0</value>
</property>
...
</key>
</result>
</get>
</server>
</packet>
For details of a response structure, refer to the Getting Server Information: License Key section.
