WhatsApp API Email Archiver

I want my Meta-hosted WhatsApp Business account wired so that every single message—both incoming and outgoing—is automatically forwarded to a dedicated archive mailbox. Each email must mirror the original WhatsApp content in full: text, sender and recipient details, timestamp, and any attached images or documents. The flow should dispatch one email per message (no batching or daily summaries).

You’re free to use the official WhatsApp Business Cloud API, on-premise API, webhooks, or an intermediary service, as long as the solution is robust and remains compliant with Meta’s policies. The designated mailbox is already active; I simply need the integration code, deployment help, and clear instructions so I can maintain or replicate the setup later.

Please propose your architecture, outline any hosting or webhook listener requirements, and estimate how quickly you can have a working proof of concept. Include any past experience with the WhatsApp Business API or similar messaging-to-email pipelines so I can gauge fit.
