+⭐ In order to run a program using the WayScript Python API, you must first add an active [Webhook Trigger](https://wayscript.com/documentation/trigger/webhook_trigger) to that program.
+
+### Running a specific function
+
+- The function you specify MUST have an active [Webhook Trigger](https://wayscript.com/documentation/trigger/webhook_trigger).
+- If you do not specify a function name in your request and your program has ***one*** function with a Webhook Trigger, the function with the Webhook Trigger will run.
+- If you do not specify a function name in your request and your program has ***multiple*** functions with Webhook Triggers, you will be asked to specify which function you would like to run.
+
 ## Run a WayScript program from command line
 ```sh
 WS_API_KEY="YOUR_API_KEY"
 PROGRAM_ID=1234
 ARGUMENT="whatever"
+FUNCTION="My Function"
 
-python -c "from wayscript import WayScript; WayScript('$WS_API_KEY').run_program($PROGRAM_ID, '$ARGUMENT')"
+python -c "from wayscript import WayScript; WayScript('$WS_API_KEY').run_program($PROGRAM_ID, '$ARGUMENT', '$FUNCTION')"
 ```
+
+If you don't want to use Python on the command line, you can use `curl`. (See the WayScript [REST API documentation](https://wayscript.com/documentation/apis/rest_api).)
