This repository contains a Bruno collection with examples of the Cost Management API. If using Bruno 3.0+, you can import directly from git; otherwise, clone the repository and open the collection locally.
Look at the Red Hat Lightspeed API cheat sheet to get started with authentication, base URLs, etc.
You will need to copy the .env.example file to .env and add proper values for client_id and client_secret
or the queries in this Bruno collection will fail due to lack of authentication.
