WhatsApp 101: the Business app, the Business Platform and the rules between them
What WhatsApp offers businesses in October 2026: the free Business app for one team on one phone, the Business Platform for systems and scale, how the 24-hour window and templates work, what Meta charges since the October 2026 changes, and where the channel fits.
The 24-hour window: the rule that breaks most first integrations
Why your WhatsApp test message worked and your production message did not: how the customer service window works, what it costs inside and outside, and how to design around it.

Templates are approved in advance, billed by category and impossible to improvise. Design the set before you need it, not during an incident.
