Retrieving List of Certificates
The get-pool operator is used for retrieving a list of certificates for a particular domain or for all administrator’s domains.
Request Packet Structure
A request XML packet that retrieves a list of certificates should include the generate operation node:
<packet>
    <certificate>
        <get-pool>
            ...
        </get-pool>
    </certificate>
</packet>
The get-pool node does not have a separate data type, it is nested
in type CertificateActionRequest (certificate_input.xsd). The node
has the following graphical representation:

- The filter node is optional. It is required if you retrieve a list of certificates for a particular domains.
- The admin node is optional. It is required if you retrieve a list of Administrator’s certificates.
Note: When creating request packets, put nodes and elements in the order they follow in the packet structure.

Note: The interactive schema navigator for all response packets is available here: http://plesk.github.io/api-schemas/1.6.9.1/agent_output.svg.
- The result node is required. It wraps the response retrieved
from the server. Data type: ResultFilterType (common.xsd).- The status node is required. It specifies the execution
status of the get-pool operation. Data type: result_status
(common.xsd). Allowed values:ok|error.
- The errcode node is required if the get-pool operation fails. It returns the error code. Data type: unsignedInt.
- The errtext node is required if the get-pool operation fails. It returns the error message. Data type: string.
- The filter-id node is optional. Data type: anySimple.
- The id node is optional. Data type: id_type
(common.xsd).
- The certificates node is required if the get-pool operation succeeds. It specifies the names of appropriate certificates.
