How to use paging to query many objects through multiple API calls

Use REST APIs to query many objects that exceed the MaxRecordCount limit using paging.

Follow the prerequisites and examples to get started with this API.

You can make API requests using the PowerShell code, C# code, Python, or any tool that supports invoking the REST API.

Prerequisites to use paging to query many objects

Read the Get started with Citrix Cloud APIs section to ensure that you have the bearer token.
Get siteid from How to get site id API.
Invoke the API described in this document from a client host.

Query many objects using any REST API tool

The following example describes how to query many machines which exceed the MaxRecordCount limit using paging. The maximum record count of the allowed is 1000 machines. For other types of site objects, apply this loop on a different request API.

If a query did not fully return the results due to a limit, the response includes a ContinuationToken string.

To obtain more results from the query, pass the ContinuationToken query parameter back into the same query to get the next batch of results. Repeat this step until the ContinuationToken value in response is null, indicating there’re no more unreturned results.

The continuationToken parameter is supported for all APIs that perform query or search on a large quantity of objects.

                MachineResponseModelCollection machinePage = JsonConvert.DeserializeObject(content);
                machines.Items.Addrange(machinePage.Items);
                machines.continuationToken = machinePage.ContinuationToken;
            }

        }

        return null;

Query many objects using Python

Learn from the following example to query many objects using any Python code.

import requests

def get_machines_in_site(bearerToken, customerid, siteid):
    request_uri = "https://api.cloud.com/cvad/manage/Machines"
    headers = {
                'Authorization': 'CWSAuth Bearer=%s' % bearerToken,
                'Citrix-CustomerId': customerid,
                'Citrix-InstanceId': siteid,
                'Content-Type': 'application/json',
                'Accept': 'application/json'
              }

    response = requests.get(request_uri, headers = headers).json()
    while response.ContinuationToken is not None:
        request_uri_page = request_uri + "&continuationtoken=" + continuation_token
        response_page = requests.get(request_uri_page, headers = headers).json()
        response.Items += response_page.Items
        response.ContinuationToken = response_page.ContinuationToken

    return response.json()
