Install the community node: n8n Settings -> Community Nodes -> npm package `n8n-nodes-wasync`.\n2. Create a free WASync account at https://developers.wasync.app/register, connect a WhatsApp number, then create an API key at https://developers.wasync.app/keys.\n3. In n8n, add a new \"WASync API\" credential using that key.\n4. Open the \"Settings\" node at the top of this workflow and fill in your own values. Never commit real portal URLs, tokens, or phone numbers.\n\nYou also need an OpenAI API key and credential in n8n for the Chat Model node. Edit the system prompt in the AI Agent node's \"Settings\" input to describe escalation rules for your own business -- refunds, complaints, anything outside what the bot should handle.\n\nDocs: https://docs.wasync.app/docs/guides/n8n?utm_source=n8n&utm_medium=template&utm_campaign=t4",
