⚡Quick answer -
Starting 1 July 2025, WhatsApp will bill per delivered template message—Marketing, Utility, and Authentication—rather than per 24-hour conversation. User-initiated “service” windows remain free for 24 hours, and Free Entry Point (FEP) chats can stay free for 72 hours if you reply within the first 24 hours.
Read on if you:
• send any WhatsApp template messages (Marketing, Utility, or Authentication) and
• want to minimise or predict new per-template charges while still offering 24 × 7 support.
• Template message – Pre-approved outbound message (Marketing, Utility, or Authentication).
• Service conversation – 24-hour window that starts when a user messages you; replies are free.
• Free Entry Point (FEP) – Chat initiated from a Click-to-WhatsApp ad or Page CTA.
• FEP 72-hour window – If you reply within 24 hours, everything stays free for 72 hours from your first reply.
Category | Typical use | Charged? | Notes |
Marketing template | Promo, abandoned cart | Always billed per send | Cost unaffected by service/FEP windows |
Utility template | Order update, reminder | Free inside 24-h service window; billed outside | Re-engagement after 24 h incurs cost |
Authentication template | OTP, login code | Always billed per send | Critical messages only |
Service (free-form) | Agent text reply | Free inside 24-h user window | Forbidden outside service window |
Alt-text: “Timeline showing 24-h reply deadline and 72-h free FEP window”
Rules:
• Reply within 24 hours to unlock 72 hours of free messaging (templates + free-form).
• Miss the 24-hour mark? You must send a paid template to restart the conversation.
Scenario | When it happens | Message type you send | Charged? | Why |
Customer asks about order | Inside 24 h | Free-form or Utility | No | Free service window |
Order update after 24 h | After 24 h | Utility template | Yes | Outside service window |
Promo during support | Inside service window | Marketing template | Yes | Marketing always billed |
OTP during login | Anytime | Authentication template | Yes | Security rule |
Ad click chat (you reply in 2 h) | FEP | Any | No | 72-h FEP window active |
Step | Where | What to check |
1 | Dashboard → Reports → Message Logs | Add columns “Template Name”, “Category”, “Charge Type”. |
2 | Billing → Invoices → Line Items | Counts per Category should match “Delivered Template” totals. |
3 | Spot-check | • Utility inside service window = $0 • Marketing inside service window = billed |
4 | Escalate issues | Collect Template ID + Message ID + timestamp → email |
• Marketing templates are always billed—even inside service or FEP windows.
• Utility is free only within the service window; the 25th hour is billable.
• Authentication is always billed.
• If you miss the first 24 hours of a FEP chat, the 72-hour free window never starts.
• Regional pricing varies; see your rate card JSON via API: /v1/account/rateCard.
• Quality downgrades can throttle throughput; maintain template relevance.
• How do Free Entry Point (FEP) windows affect WhatsApp template charges?
• Which webhook events show template billing status in real time?
• Best practices for lowering WhatsApp Marketing template costs.
