REST client headers
The HTTP Client (such as Postman) Headers provide the required url/queries to allow users to page through results, given the 1,000 record limit per display. For example, the below shows a query to return all GP Practices (Non Primary Role ID of RO76). This query returns 8,377 records, with the maximum 1,000 record limit on the display. The Postman Header details the 'total count' and 'returned records' but then also provides the 'next page' url/query:
Once the 'next page' url is queried and the next page of results returned, the Header will display the url for the 'previous page' as well as the 'next page', allowing users to tab through all 8,377 results.
