Pagination
All GET endpoints which return an object list support cursor based pagination with pagination information inside a pagination object. This means that to get all objects, you need to paginate through the results by always using the id of the last resource in the list as a starting_after parameter for the next call.
To make it easier, the API will assign the next call into next attribute together with all the currently used pagination parameters. You know that you have paginated all the results when the return is empty (next value will be undefined, as well).
Using cursor-based pagination protects against the situation when the resulting object list changes during pagination (new resource gets added or removed).
The default limit is set to 20 but values up to 100 are permitted.
