I am building an agent for WhatsApp, handling both text and audio, as well as a calendar integration. I want to know your thoughts on using Evolution API, Easy Panel, and the official WhatsApp Business Platform. What is the best platform for handling long and short-term memory? What is the best database integration to handle this data? Also, what is a better chat model than OpenAI? I need guidance on a practical approach to ensure that the agent works perfectly as soon as I set it to active and in production. My goal is for the webhook trigger to listen to events without getting stuck, so I don’t have to worry about performance.
