After an API url which supports paging, add the 'page' and 'pagesize' querystring part, e.g. myapiurl?page=1&page=20
Note that BOTH the page and pagesize need to be specified - there are no defaults if one is omitted.
If any sorting or filtering are done using properties on nested objects, e.g. nestedobject.property, then it is highly likely that paging will perform much slower as the pages will be calculated in-memory rather than directly against the underlying data set
