Keep the Business App, build the workflow in n8n: Dualhook
This is what we do best. Dualhook onboards your number through Meta's Embedded Signup and sets a Webhook Override on your WhatsApp Business Account, so Meta sends messages, statuses, app echoes, history and contact sync straight to your n8n Webhook URL with no provider hop. Dualhook stores no message content, your account stays in your own Meta business portfolio, and it reminds you at 13 days, ahead of Meta's approximate 14-day primary-device inactivity window. Sends go through api.dualhook.com with a per-connection key and the same paths and JSON as Meta's Graph API. Pricing is flat: $12/month for 1 connection, $25/month for up to 5, and $45/month for up to 10, with Meta's fees billed to you directly. It is an official, badged Meta Tech Partner, and every plan includes a 14-day free trial.
