Messenger Integration Guide

Goal

Provide a practical baseline for integrating Facebook Messenger: app setup, webhooks, messaging flows, and safe operations.

Use when

• You need a Messenger bot for notifications or support.
• You need to describe webhook validation and event handling.
• You want a security/rate-limit checklist.

Do not use when

• The request involves policy violations or spam.

Core topics

• App and Page setup, tokens, permissions.
• Webhook verification and signature checks.
• Message types: text, templates, attachments.
• Ops: rate limits, retries, logging.

Required inputs

• App/Page ownership and use case.
• Deployment model and environment.
• Access control and compliance constraints.

Expected output

• A clear integration plan with a technical checklist.

Notes

• Never expose Page access tokens.
• Validate webhooks and handle retries safely.
