The get operation applied to subscriptions returns their lock and sync statuses if the operation packet contains the subscriptions node. In addition, such requests will return plans and add-ons associated with each subscription. The subscriptions node that stores all these details is specified by complex type SubscriptionsList (plesk_domain.xsd) . This type is structured as follows:

• The subscription node is optional. It nests the data about statuses and the plans. Data type: none.
• The locked node is required. It holds the subscription lock status. In other words, it tells whether a subscription is not updated on associated service plan updates. Data type: string.
• The synchronized node is required. It specified whether a subscription is synced with the Panel components (for example, Business Manager). Data type: string.
• The plan-guid node is optional. It specifies the GUID of an add-on plan that will be added to the subscription. Data type: string.
• The plan-external-id node is optional. It specifies the ID of a service plan in the Panel components (for example, Business Manager). Data type: string.

The following snippet illustrates how this structure appears in packets:

<subscriptions>
  <subscription>
    <locked>false</locked>
    <synchronized>true</synchronized>
    <plan>
      <plan-guid>b9808ead-875a-c30f-d9bf-eb03ad12c89c</plan-guid>
    </plan>
    <plan>
      <plan-guid>f42428e7-9078-5ed8-50de-fd5ecfb5ecc6</plan-guid>
    </plan>
  </subscription>
</subscriptions>
