​ Select a Function to Call

The function dropdown will contain the available functions to call in your program.

​⚙ Choose Your Inputs and Outputs

Once you select a function to call, the inputs and outputs for that function will populate in the settings panel. Select your inputs and outputs as you would for any module.

​🔀 Running a Function Asynchronously

The Run Async setting in the Function Call module allows you to asynchronously call a function that runs an "expensive" or long-running task. One common use-case for this setting is to immediately return a 200 Success response from the HTTP Response module, while performing a long-running task in the background, on another thread.
