Implementation overview

A reliable integration has four parts: Meta setup, a secure webhook receiver, outbound template sending, and durable storage of events. Treat message IDs as primary keys and design for retries and idempotency.

Once events are normalized, you can connect them to CRM records and trigger actions. See Webhooks and Workflows for event-driven patterns.

Faster Handoffs

Bring PHP integration sequence and webhook flow into one shared workspace with roles and rules.

CRM Alignment

Every WhatsApp exchange maps to customers, deals, and follow-ups.
