Infrastructure overview

The application runs on a mix of Docker Compose (all app services), Meta WhatsApp Business API (webhooks and messaging), and AWS (EC2 for hosting; optional S3 for log backups). Caddy provides the public entrypoint and TLS in production; Ngrok is used in development to expose the webhook locally. This section is split into separate pages:

Page	Contents
Docker	Compose services (web, celery, beat, db, redis, admin-portal, docs, caddy, ngrok), ports, volumes, and dependencies.
Meta & WhatsApp	Meta Webhooks (verification and POST), connection to WhatsApp Business API, and using WhatsApp template messages.
AWS	EC2 hosting and Elastic IP (placeholder).
Caddy	What Caddy does, why we use it, and how subdomains map to services (api, admin, docs).
Ngrok	What Ngrok does, why we use it for local webhook testing, and how it is configured.

For a quick run from scratch, see Quickstart. For scheduling and background tasks, see Scheduling.
