I have tried everything, and keep running into this error. No other apps connected with Zaps are having issues. I am attempting to connect Gravity forms from my website to Service Titan. When someone submits a form, it should create a new booking. Unfortunately it is stating that each booking needs a unique Booking Provider ID and External ID. I have never run into this with other apps.
Failed to create a booking in ServiceTitan
The app returned "A booking with AgentTagId 183543231 and ExternalId 651c7ae2-c923-417c-ad78-4fe4ba46707e already exists".
