Hi Poppy pearce,
Qlik Rest Connectors:
The Qlik REST Connector enables Qlik Sense and QlikView to efficiently load data into Qlik apps from a REST data source. Many web-based data sources expose data through a REST API. The Qlik REST Connector is a generic connector, that is, it is not tailored to a specific REST data source.
Qlik Web Connectors:
The Qlik Web Connectors package is a light-weight web service that helps you fetch data from many social media and web-based data sources. The Qlik Web Connectors help you connect to your social media or web-based data source through the specific web APIs and fetch the data that you want. All you have to do is select what kind of data and how much data you want to fetch then the Qlik Web Connectors generate Qlik Sense and QlikView load scripts that you can paste into script editor.
Hope this will help in getting an idea Poppy.
