Welcome to the Make community!
You can use a Custom Webhook as the scenario trigger, and Webhook Response to send the result back to your terminal.
Then, in your terminal you can type:
curl 'https://make-webhook-url.goes-here' --data-urlencode 'param1=value 1'
Repeat --data-urlencode 'param1=value 1' for each variable you want to send to the scenario, or omit if no variables are needed.
For more information, see bash - How to urlencode data for curl command? - Stack Overflow
Hope this helps! Let me know if there are any further questions or issues.
