Can do this on the dashboard pretty easily: 1. Go to functions tab when creating the assistant, add a new custom function and fill it out how you’d like (title, description, properties/input needed for the action you want to do) 2. Create a new scenario in Make where the first module is a webhook. The webhook URL that Make gives you should be the server URL for your custom function. 3. From there, you can just do whatever business logic in Make and send a webhook response at the end of the Make scenario to let your assistant know the end result of the custom function/action
