# WhatsApp Business API: official support and transactional messages

Category: Webchat, Messenger and WhatsApp


Verified green-tick profile sends order confirmations, invoice PDFs and warranty letters in chat, plus the courier's live tracking link on delivery morning. The customer replies 'deliver Friday, I'm away' and the AI reschedules with the courier and confirms.

## How it works

1. Transactional messages from shop events
2. Two-way changes handled with the courier API
3. Confirmation back to the customer

Tools: WhatsApp Cloud API, Shopify, GLS
