javascript with zapier automations. i have a couple work flows i built for chain-of-resoning for negotations with the user after a price estimate. and i built a chain of thought for the price estimate that takes into account the vehicle scrap value that i get and process. then it uses the client info details for damage and condition to offer a bit more on top of scrap value. it's been a challenge but it works and it's a lot of fun to use.
