How to create and run an API call (get request) in Linux server

I have created a test using Neo Load Designer (GUI), its an API call which uses get request which connects to AWS service and get the response. Now I wants to implement the same test in AWS cloud with Linux instance. I have created a Linux EC2 instance and installed Neload Controller 6.7 successfully. As linux wont support GUI, I wonder like which commands will support to create this scenario/test in linux server.

I have reviewed the below links but it could not help much..
