If there are more records than 'limit' (between 1 and 100), and there are multiple pages of records, 'pageToken' allows for retrieval of individual pages. In order to retrieve subsequent pages, the client should provide the pageToken returned in the result from the previous API call as input to the following API call.

Example: If the result for a call to GET /items returns {..., "pageToken": "abcdefg"}, in order to retrieve the next page of 'items' the client should call GET /items?pageToken=abcdefg
