Hi team, sorry for the long messages... trying to provide more context on my question. Please let me know if there are better ways of asking these type of questions: **Goal**: learn the best practice while integrating my backend server and Vapi I will use the use cases from the agent I am building as a media for my questions. Agent description: I am building an agent as a personal secretary to handle incoming calls properly. It should pass through the call when it finds the incoming call legit otherwise denies the call. Where am I: Now I have my vapi assistant ready and I can chat with it. **Next**: I want to add more functionality to this agent with the following use cases *Use cases: * * During the conversation, I want to analyze the call in real time to log the transcript and potentially generate some data as input for the following prompts * I want my agent to check my Google Calendar availabilities before deciding if it should pass through the call * Right before passing through the call, I want my agent to send me a text message summarizing the current conversation so I can have the context. My thoughts/questions: * Is it even necessary to have a backend server for my use cases above? It seems the answer is yes to me unless I am aware of some existing features of Vapi * What would be the general practice of integrating a server logic into voice agent? E.g. only relying on webhook? Adding logic after vapi receive the speech-text but before sending it LLM in order to add dynamic info to the prompt? Thanks in advance!
