Practical guides for
WhatsApp Business API

Meta changes WhatsApp prices on 1 October 2026. Support replies in the 24-hour window are no longer free. This 1MSG guide shows what that means for your invoice, and how to keep extra cost small.

Bulk WhatsApp messaging scales only on the official WhatsApp Business API: opted-in recipients, a Meta-approved template, and a throttled sendTemplate loop. New portfolios start at 250 unique recipients per rolling 24 hours, scaling to 2,000, 10,000, 100,000, then unlimited. Track every send by wamid and halt before the cap.
