Hello Prakhar,
So it’s working now.
newman run “https://api.getpostman.com/collections/9999999-3d5e3244-9408-efbb-7767-999999999999?apikey=99999999999999999999999999999999” -e DEV1_Environment.json
My problem was I had not wrapped my URL in double quotes and so I suspect the shell was helping me by further interpreting my command and make a mess of things.
