WhatsApp Business API pricing per message

How per-message costs map to WhatsApp’s conversation-based pricing model.

WhatsApp Business API pricing is technically per conversation, but you can estimate per-message impact by looking at how many messages you send within each 24-hour window.

Key takeaways

Meta bills per conversation window; multiple messages inside a window do not increase Meta charges.
Per-message cost depends on how many messages you send in that conversation window.
Providers may charge per message or per conversation—check their pricing model.

Conversation vs per-message math

Divide conversation cost by average messages sent in that window to estimate per-message cost.
Higher message volume inside a single conversation lowers effective per-message cost.

When per-message matters

Some providers price by conversation plus a small per-message fee. Understand both to budget accurately.

Tips to optimize

Batch updates within an existing conversation window when appropriate.
Use concise, value-driven templates to reduce retries or new windows.
Monitor average messages per conversation to benchmark efficiency.

FAQs

Meta charges are per conversation, not media type. Providers may have storage/bandwidth fees for heavy media usage.

Can per-message pricing cause overages?
