All lists implement the same method for pagination with page and per_page parameters, eg.

curl --request GET \
     --url 'https://demo.spreecommerce.org/api/v2/storefront/products?page=1&per_page=25' \
     --header 'Accept: application/vnd.api+json'

Both of these parameters are optional. There is a limit of 500 records that can be fetched by a single request. If this doesn’t work for your use case, please contact us so we can work on resolving this issue.

Response for that call will include a meta node with:

"meta": {
  "count": 25,
  "total_count": 26,
  "total_pages": 2
}

count is the number of records returned on the current page
total_count is the total number of records in the collection
total_pages is the total number of pages

The response will also include thelinks node:

"links": {
    "self": "https://demo.spreecommerce.org/api/v2/storefront/products?per_page=25",
    "next": "https://demo.spreecommerce.org/api/v2/storefront/products?page=2&per_page=25",
    "prev": "https://demo.spreecommerce.org/api/v2/storefront/products?page=1&per_page=25",
    "last": "https://demo.spreecommerce.org/api/v2/storefront/products?page=2&per_page=25",
    "first": "https://demo.spreecommerce.org/api/v2/storefront/products?page=1&per_page=25"
  }
