List endpoints that can return many records, such as Get Assets, return them in pages. You set the page size, and a continuation token takes you to the next page.

Request a page

Add page_size to the query string:

curl --request GET 'https://talk.perspio.io/assets/v3/?page_size=100' \
  --header 'Authorization: Bearer {access_token}' \
  --header 'tid: {tid}' \
  --header 'Ocp-Apim-Subscription-Key: {subscription_key}'

The response headers describe the page:

Header	Meaning
`ResultCount`	Records in this page
`TotalCount`	Records that match the request across all pages
`ContinuationToken`	Present when there are more pages. Send it back to get the next page

Get the next page

Repeat the same request with the token in a ContinuationToken request header. When a response comes back without a ContinuationToken, you have every record.

$headers = @{
    Authorization               = "Bearer $accessToken"
    tid                         = '{tid}'
    'Ocp-Apim-Subscription-Key' = '{subscription_key}'
}
$all = @()
do {
    $response = Invoke-WebRequest -Uri 'https://talk.perspio.io/assets/v3/?page_size=100' -Headers $headers
    $all += $response.Content | ConvertFrom-Json
    $token = $response.Headers['ContinuationToken'] | Select-Object -First 1
    $headers['ContinuationToken'] = $token
} while ($token)

import requests

headers = {
    "Authorization": f"Bearer {access_token}",
    "tid": "{tid}",
    "Ocp-Apim-Subscription-Key": "{subscription_key}",
}
records = []
while True:
    response = requests.get(
        "https://talk.perspio.io/assets/v3/", params={"page_size": 100}, headers=headers, timeout=60
    )
    response.raise_for_status()
    records.extend(response.json())
    token = response.headers.get("ContinuationToken")
    if not token:
        break
    headers["ContinuationToken"] = token

Check each endpoint
Endpoints that page list page_size and ContinuationToken on their reference page. A few use other parameters instead, such as take or limit. The endpoint page shows which.
