Importing Application Package to Plesk
The import-package operation is used to import to Plesk an application package uploaded to the server.

<packet version="1.6.2.0">
<aps>

Samples
Request packets importing to Plesk the APS package previously uploaded to the server looks as follows.
On Linux/Unix:
<packet version="1.6.2.0">
  <aps>
    <import-package>
      <filename>/usr/local/psa/tmp/li_8FZruf</filename>
    </import-package>
  </aps>
</packet>
On Windows:
<packet version="1.6.2.0">
  <aps>
    <import-package>
      <filename>"C:/Program Files/Parallels/Plesk/tmp/li_9D.tmp"</filename>
    </import-package>
  </aps>
</packet>
Response:
<packet version="1.6.2.0">
  <aps>
    <import-package>
      <result>
        <status>ok</status>
        <package-id>13</package-id>
      </result>
    </import-package>
  </aps>
</packet>
Such negative response is received if a requested file is not found:
<packet version="1.6.2.0">
  <aps>
    <import-package>
      <result>
        <status>error</status>
        <errcode>1013</errcode>
        <errtext>File "/usr/local/psa/tmp/li_8FZruf" does not exist</errtext>
      </result>
    </import-package>
  </aps>
</packet>
Such negative responses are received in cases a file being imported is not a valid APS application package.
1) The archive being imported lacks APP-META.xml package metadata
file.
<packet version="1.6.2.0">
  <aps>
    <import-package>
      <result>
        <status>error</status>
        <errcode>1023</errcode>
        <errtext>Entry 'APP-META.xml' not found</errtext>
      </result>
    </import-package>
  </aps>
</packet>
- 
APP-META.xmlis not validated against the XML schema.
<packet version="1.6.2.0">
  <aps>
    <import-package>
      <result>
        <status>error</status>
        <errcode>1023</errcode>
        <errtext>Unable to acquire metadata description</errtext>
      </result>
    </import-package>
  </aps>
</packet>
