Why answers online and from AI assistants often differ
In 2 years, WhatsApp API pricing changed on 1 November 2024, 1 July 2025, 1 August 2026, and 1 October 2026. Before that, Meta gave 1,000 free conversations per month. AI assistants and old articles often mix rules from different years, so 2 answers to the same question can conflict.

4 questions that decide if 1 message is charged
Every WhatsApp API message has exactly 1 pricing category. Meta writes that 1 message gets only 1 charge, per its category. You can find that category with 4 questions in order.
1. Who sends the message?
Meta charges only messages from a business to WhatsApp users. Messages from customers to the business are always free, in any quantity. Source: the How Meta charges across message types part.
2. Is the message a template?
A template has the marketing, utility, or authentication category. For an Indonesian recipient, marketing costs Rp586.33 and utility and authentication cost Rp356.65 per message.
A non-template message in the 24 hour window is a service message or a Meta Business Agent message. Examples are text, images, documents, and Flows.
3. Which window is open?
The 24 hour window opens each time the customer sends a message. Non-template messages can be sent only in this window.
The 72 hour FEP window opens when the customer comes from a Click to WhatsApp ad or a Facebook Page button on a phone. The business must also reply within 24 hours. Source: the Free entry point windows section.
Inside the FEP window, every business message is free, templates too. This rule does not change on 1 October 2026. The exception: Meta Business Agent still pays tokens.
4. Which service message is this for the number this month?
Every business number has 1,000 free service messages per month. Message 1,001 onward is paid at the service rate of the recipient market.
For Indonesia the rate is Rp356.65, with no volume tiers. Source: the Service rates effective October 1, 2026 part.

| 4. Meta Business Agent replies | Yes, since 1 August 2026 | 2 US dollars per 1 million tokens, about 4 to 5 cents per message | Meta Business Agent |
| 5. Replies within 72 hours after a Click to WhatsApp ad click | No, when the business replies within 24 hours | Rp0 | Free entry point |
| 6. An order confirmation (utility) when the customer has just written | Yes, from the first message | Rp356.65 | Utility |
| 7. A delivery status (utility) after the 24 hour window closes | Yes, as before October | Rp356.65 | Utility |

| 11. A reply to a customer with a Malaysian number | Yes, after 1,000 messages per business number | Rp199.82 | Service |
| 12. A reply from the normal WhatsApp Business app | No | Rp0 | Not the WhatsApp Business Platform |
Source for rows 1 to 11: the Meta pricing document and the IDR rate card effective 1 October 2026. Row 12: the WhatsApp Business FAQ, which says that the WhatsApp Business app is free to download and free to use. Messages that fail to deliver are not charged in any case.
What you need to check it yourself
- WhatsApp Manager access to open Insights › Message pricing.
- The list of active templates with their categories, from Message templates › Manage templates.
- The chat source: a Click to WhatsApp ad, a Page button, or a normal chat.
- The count of service messages per business number since day 1 of this month.
- For developers: access to the message status webhookWebhookAn automatic message one system sends to another the moment something happens, for example an incoming WhatsApp message.Open the glossary, field
pricing.
Step 1: Find out who sends the message
Look at the direction of the message. When the customer sends a message to the business number, it is Rp0 and you are done. When the business sends it, from staff, a chatbot, or a system, go to step 2.
Check the result in Insights: the All Messages card separates Messages received (incoming messages) from Messages delivered (delivered business messages). Only the second number can become a cost.
Step 2: Find out if the message is a template
Open Message templates › Manage templates, then find the template name. The Category column says Marketing, Utility, or Authentication. When the message is not a template, go to step 3.
Meta charges the category in force at the time the template is used. So check the category before a large send, because Meta can change the category of a template. Source: the Template messages vs. non-template messages part.
Step 3: Find out which window is open
Check if the customer came from a Click to WhatsApp ad or a Page button on a phone. If so, the 72 hour FEP window opens when you reply within 24 hours. Every business message in that window is Rp0.
Developers can read the pricing.type field in the status webhook. The value free_entry_point means that the message is free because it is in the FEP window. Source: the Status messages webhook reference.
Step 4: Count the position of the service message for the number this month
Count the delivered service messages from that number since day 1. When this message is at position 1 to 1,000, it is Rp0. From position 1,001, it costs Rp356.65 for an Indonesian recipient.
From 1 October, the webhook marks messages above the tier with "type": "regular" and "billable": true. How to set up the counter is in step 8 of the cost guide.
Worked example: 1 buyer from a Click to WhatsApp ad over 5 days
The table below is a simulation with dummy data. The buyer uses an Android phone and comes from a Click to WhatsApp ad on Monday at 09:00. The business number has already passed 1,000 service messages this month.
| Time | Message | Open window | Cost |
|---|---|---|---|
| Monday 09:00 | The buyer clicks the ad and asks about stock | The 24 hour window starts | Rp0, an incoming message |
| Monday 09:05 | The business replies that the item is in stock | The 72 hour FEP window starts, until Thursday 09:05 | Rp0 |
| Monday 09:20 | 4 more replies and 1 utility template to confirm the order | FEP | Rp0 |
| Wednesday 10:00 | The buyer asks about the status, the business replies | FEP, and a new 24 hour window until Thursday 10:00 | Rp0 |
| Thursday 12:00 | The business sends a utility template: order shipped | No window; FEP and the 24 hour window are closed | Rp356.65 |
| Friday 08:00 | The buyer writes "it arrived", the business says thank you | A new 24 hour window | Rp356.65, because the tier of the number is used up |
Of 9 business messages, only 2 are paid. The total cost is Rp713.30. With no Click to WhatsApp ad, the first 7 messages would fall in a normal 24 hour window and count too.

- Support staff tag chats that come from Click to WhatsApp ads. Evidence: a chat label or the Free entry point number.
- Support staff check the reply count per question in the last 20 chats. Evidence: a note of messages per chat.
- A developer makes sure the chatbot sends no double greetings or needless intro messages. Evidence: a 1 day log.
- The owner checks group messages sent through the API. Evidence: the recipient count per send.
- Finance makes sure a payment method is active before 30 September 2026. Evidence: a Billing Hub screenshot with no card number.
- Stop criterion: when service messages per business number stay below 800 per month for 2 months, run this checklist once per quarter.
Frequently asked questions
Do images, documents, and voice notes from the business also count? Yes. Every non-template message from the business in the 24 hour window is a service message, including images, documents, and audio. All of those types use the same 1,000 tier.
Are messages that fail to deliver still paid? No. Meta charges only messages with the delivered status. Failed messages do not use the tier and do not show as a cost.
Do WhatsApp group messages count per group or per member? Per member who receives the message. 1 send to a group with 20 recipients uses 20 units of the number tier, and is paid per recipient after the tier runs out.
What is the reply rate for customers in Malaysia, Singapore, or Saudi Arabia? The rate follows the recipient country. On the IDR rate card of 1 October 2026, the service rate is Rp199.82 for Malaysia and Rp228.35 for Singapore. It is Rp152.54 for Saudi Arabia and Rp224.11 for the United Arab Emirates.
Does Meta Business Agent use the 1,000 free message tier? The Meta documents name the 1,000 tier for service messages only. Meta Business Agent is a separate category with a token rate since 1 August 2026, and it is still charged in the FEP window.
Will BSPs raise their prices on 1 October? Meta charges service messages to the BSP or to the directly connected business. The WhatsApp Business FAQ says that partners can charge additional fees, so check the price list and invoice of your BSP.
Next step
Limits of these answers: Meta has not written if messages in the FEP window use the 1,000 tier, and Insights numbers are approximate. When you need rupiah numbers per business number, use the formula and the 8 steps to calculate the cost.
