Have you tried to paginate the response to get the full list?
Here is a helpful forum post on that :
Please provide more details about the issue you are facing regarding the lack of clarity for retrieving next page data using cURL in PHP. Can you explain what you have already tried and what the resulting outcome was? If possible, please share a code snippet that I can test on my end. Additionally, it would be helpful if you could provide a screenshot of the response you are receiving from the server.
