I need a ready-to-deploy WhatsApp chatbot built entirely in n8n. The flow must cover two core abilities: automated replies triggered by keywords or user intent, and clear interactive menus that guide users through available options without human intervention. Here’s what I expect: • A clean n8n workflow file that I can import, edit, and expand on my self-hosted instance. • Step-by-step notes on any environment variables, credentials, or webhooks I must configure so the bot connects smoothly to my existing WhatsApp Business API number. • A brief video or screenshot walkthrough confirming the bot handles at least three sample conversations, demonstrating both automatic responses and menu navigation. I’ll test by importing the workflow, firing a few WhatsApp messages, and confirming replies arrive instantly and the menus branch correctly. Once that runs error-free, the job is done.
