Let’s start with the two most used methods to access REST Services: the GET Request and the POST Request.
A GET Request is sent to a REST service from within a KNIME workflow via the GET Request node. Similarly, a POST Request via POST Request node.
Below is the video explaining how to build a GET request in a GET Request node.
Example workflows about accessing REST services can be found on the EXAMPLES server in: 01_Data_Access/05_REST_Web_Services01_Data_Access/05_REST_Web_Services*
* The link will open the workflow directly in KNIME Analytics Platform (requirements: Windows; KNIME Analytics Platform must be installed with the Installer version 3.2.0 or higher)
