Dispatch
Rails, templates, numbers and what Meta bills for.
Messages stopped sending: a diagnostic order of operations
Work from the outside in: the number, the session, the recipient, the window, the payload. The order that finds the cause fastest.
Linked devices: what a session is, and why sending stops
Multi-device changed what a WhatsApp session is. What ends one, what does not, and what to check first when messages stop leaving.
Forms inside a chat: when a flow beats a conversation
Structured, multi-screen input inside WhatsApp. What it is good for, and the two cases where a person asking beats any form.

What a catalogue can hold, how product messages behave, and why the checkout still happens somewhere else for most businesses.
WhatsApp groups for business: what they are good for, and what they cost
Groups are a broadcast channel where every member can see and message every other member. What that means before you add 200 customers.

The number stops working in the app the moment it moves. What to do before, during and after, and what you cannot bring with you.
Quality rating and messaging limits: the dial you cannot see
Meta scores your number on recipient feedback and moves your daily limit up or down. What raises it, what drops it, and what a flag means.
The green tick: what it is, who gets it, and whether you need it
Official Business Account status is granted on notability, not on paperwork. What Meta looks for, and what the badge does not do.
