I've had one challenge that has persisted for a long time now. I simply want to send custom structured data to the call during the assistant-request. Nothing I try works. The agent cannot see any variable data that I send and I am forced to use a tool call which is very clunky for structured data that should be consistent throughout the duration of the call. How can i simply send a json object that the agent can actually see and use during the assistant request? (i've tried customData, messages, standalone json objects, etc.). BTW customData was recommended by the ChatGPT VAPI assistant multiple times and it is not supported when it is included in the request. To clarify: I can send a tool call and the assistant can read it great, but I have to produce that same data every single time the tool gets called. This wastes resources, bandwidth, and clutters up the communications. I want to send my assistant real-time data that is good for the entire duration of the call. Not a single variable, but knowledge it can use easily. I seem to be able to send something that might be accessible here and there, but I always have to coerce the agent, at best, to utilize the data. Hopefully you have a resolution for this, what I believe, is an extremely important topic. Thanks, Alan
