Abstract
This code snippet is a subset of Code snippet to make an HTTP call and request data. It accesses a REST API, and thus requests JSON data and returns the parsed data through a Groovy script written in the Groovy editor of the add-on.
Logic
- Import the HTTPBuilder, GET request methods and the JSON content type method.
- Access the REST API by creating a new HTTP instance.
- Request the JSON data passing the method as GET, the content type as JSON, and the request configuration closure to the request method.
- Return the parsed JSON data from the response.
