Hi I am having a few issues and would love some community feedback on how to overcome them. 1. I have a backend and plan to use Vapi api request tool to interact with them. But this does not send out a ToolCallID which I need to ensure idempotency (read: avoid multiple tool calls) for my backend. Is there a way to do this? 2. If i instead use a custom tool template from Vapi i get the ToolCallID but the result needs to be a string instead of a json object. Is there a way I can get both ToolCallID for idempotency and json object results? Thanks alot. 😆
