Playing around with Vapi again tonight trying to figure out the appointment setter aspect. Spent some time last week with a tutorial by Jannis, tonight im on a video by Henryk and both are a month + old, and im not getting the same results even though I going step by step with them. I get totally lost in postman, and the creators seem to make assumptions about what we know so the skip over bits. Anyone have a video that they found helpful they would recommend?
