Give your Widget a name (in this example, post_to_slack is used). Drag a Make HTTP Request Widget onto the Canvas from the Tools & Execute Code section of the Widget Library, and connect the red dot from the Incoming Message trigger to the gray dot in the upper left corner of the Make HTTP Request Widget. This Studio Flow only requires one Widget - the Make HTTP Request Widget. In this case, your trigger is going to be an Incoming Message. It will kick off your Flow when the trigger you specify is fired. You’ll notice that the Canvas comes with a Widget already in place – that’s the Trigger (Start) Widget. You'll see a few different templates you can use but you'll want a blank Canvas for this tutorial, so select Start from scratch on the template selection screen.
