For those APIs, the “page” and “perPage” are the path parameters. After calling the API, you can detect the “paging” object in the response and decide to read the next page or not by calling the API again with the same body params and adding the page index to the query param.

E.g.

bodyParams = {
    'grouping': {
        'groupBy': "Users"
    },
    ...
}

queryParams = {
    'page': 2,
    'perPage': 100
}

endpoint = '/analytics/calls/v1/accounts/~/aggregation/fetch'
resp = platform.post(endpoint, bodyParams, queryParams)

See the dev guide for more code.

To detect and control the API rate limit, please read this article and implement some delay in your code, the example is in Node JS, but you can use easily use the time.sleep() method in Python to cause the delay.

I highlight the code where you can detect the limit values here.

headers = resp.response().headers
limit = int(headers=‘X-Rate-Limit-Limit’])
remaining = int(headersi‘X-Rate-Limit-Remaining’])
window = int(headers>‘X-Rate-Limit-Window’])
