Retrieving Articles through REST API

Hi

I'm trying to get an overview of the articles we have in Zendesk to match them to a set of KPI's we have. I'm currently using the following REST API:

https://<company>.zendesk.com/api/v2/help_center/articles.json

However by default I'm not receiving all information since the API uses pagination. I'm connectin with Qlikview REST API and I have the following fields to fill in :
- Next_page parameter -→ I set this to next_page with value 0
- Page size parameter -→ I set this to per_page with value 100

- Total pages parameter-→ can't find this in Zendesk API documentation
- Data Indicator Path -→ Can't find this in Zendesk API documentation

Any help would be appreciated.
