Everything required to get the WhatsApp Business API live in 2026 — Meta Business Portfolio, phone number rules, tokens, webhooks, and verification — explained step by step.

If you've built anything on the WhatsApp Business Platform, you've hit one of these at some point: a template that silently fails, a token that stops working overnight, a broadcast that sends fine for 200 contacts and then throws errors for the rest.

Clerical work consumed the time teams needed for their sales pipeline, and moving a number to the API meant sacrificing conversational data — or hesitating to grow at all because starting over felt too risky.
