Dynamic API Pagination with next page Cursor in a Record



I am having issues with writing a custom Query to get some data from an API.

In the initial response, I get these 2 results:


  data - (that has the 1st page of the data needed) and "pagination" which has this:



In order to get the next page of data, we need to make another API request with the value from endCursor added to the API uri in this format (


I've looked trough everything on the forum here and on the internet but I still can't find a suitable solution for this issue.


I'm sure that I need some kind of a loop that will add all the data in one list and request the next page of data using the endCursor value till there are no next pages (endCursor = "";  or hasNextPage = FALSE)


Thanks for your support!

Here is what my data looks like in regard to the API loop:

Here is the query I've made but it does not work. It keeps saying "The field 'pagination.hasNextPage' of the record wasn't found.

I am in need of code assistance if anyone is willing to help me.

Did you ever figure this out? I am trying to do the same thing with Samsara and am so close but can't seem to get it exactly right. Any help would be greatly appreciated! Thanks

Here is a copy of the Pagination code from the API documentation:


import requests

url = ""
params = {}
headers = {
    "Authorization": "Bearer TOKEN"

hasNextPage = True
while hasNextPage:
    response = requests.request("GET", url, headers=headers, params=params).json()
    for vehicle in response["data"]:
        # process each vehicle
    hasNextPage = response["pagination"]["hasNextPage"]
    params["after"] = response["pagination"]["endCursor"]


I'm having a hard time translating this into M script. Can someone help me out with the M code that would work?

Hi, @Smiljanska 

You need to implement a for-loop using List.Generate.

About how to implement Cursor-Based Pagination using List.Generate to extract large data sets from Web APIs, please refer to below thread.
