WhatsApp Business API Pricing Guide

- After 24 hours, you must use template messages (with applicable charges)
2. Free Entry Points
When customers contact you through specific Meta advertising channels, you get an extended free messaging period:
Qualifying entry points:
- Ads that Click to WhatsApp - Facebook/Instagram ads that open WhatsApp

3. Utility Messages in Response
When a customer initiates a conversation and you respond with a utility message within the service window, that utility message is also free.

Template messaging costs will depend on the target phone country and type of templates you send (marketing, utility or authentication).

Frequently Asked Questions
Do I pay if a message fails to deliver?
No. You are only charged when a message is successfully delivered to the recipient.

Rates are based on the recipient's country, not the sender's location. If you're in the US sending to Brazil, you pay Brazil rates.

Currently, volume discounts only apply to utility and authentication messages. Marketing messages have fixed rates per country.
What happens if my template is recategorized?
If Meta recategorizes your template (e.g., from utility to marketing), the new rate applies immediately. Review template categories regularly.
Are media messages (images, videos) more expensive?
No. All message types within a category have the same rate, whether text-only or including media.
How often do rates change?
Meta typically announces rate changes with advance notice. Check the official Meta documentation for the latest rates.
