User-Initiated Conversation

A user-initiated conversation is any WhatsApp Business API exchange that the customer starts — a reply to your ad, a message to your click-to-WhatsApp link, a "hi" to your number, or a tap on a QR code. The moment their message arrives, a rolling 24-hour service window opens during which your business can respond with free-form messages at no per-message charge. It is the counterpart to a business-initiated conversation, and understanding the difference is the single biggest lever Indian businesses have over both their WhatsApp cost and their customer experience.

In one line

A user-initiated conversation is a WhatsApp chat the customer opens. It starts a free 24-hour service window where your team can reply with free-form messages without triggering a template charge — but sending outside that window, or sending a marketing/utility template inside it, is still billed per delivered message by category.

What counts as a user-initiated conversation

A conversation is user-initiated whenever the customer sends the first message in a fresh 24-hour cycle. That first message can arrive through many entry points, and each one is a common way Indian businesses seed inbound WhatsApp volume. What they all share: the customer acted first, so WhatsApp treats the resulting window as a service window rather than an outreach you paid to start.

  • A direct message or 'hi' to your WhatsApp Business number
  • A tap on a click-to-WhatsApp (CTWA) ad on Facebook or Instagram
  • A scan of a WhatsApp QR code on packaging, a receipt, or a storefront
  • A click on a wa.me / short link on your website or in your email footer
  • A reply to a template you sent — their reply re-opens or refreshes the service window

The 24-hour service window is free time, not a billing unit

This is the point most teams get wrong. Since 1 July 2025, Meta bills WhatsApp per delivered message by template category — marketing, utility, or authentication — and it retired the old per-conversation charge. The 24-hour window is now purely a free service window: once a user-initiated conversation opens it, your agents (or your bot) can send unlimited free-form service replies to that customer for 24 hours without incurring a template charge. Each new inbound message from the customer keeps the window rolling forward another 24 hours. The window controls when you may send free-form content and when you are forced back to approved templates — it does not, by itself, generate a per-conversation bill.

Why it matters for cost and compliance

User-initiated conversations are the cheapest, highest-trust way to talk to customers on WhatsApp, because inside the service window you answer support questions, share order details, and resolve issues using plain free-form messages instead of pre-approved templates. That lowers cost and removes template-rejection friction from everyday service. It also matters for compliance and quality: customers who started the chat are far less likely to block or report you, which protects your quality rating and messaging tier. Design your flows to invite inbound contact — CTWA ads, QR codes, and link entry points — and you convert more conversations into free service windows instead of paid outreach.

  • Free-form replies inside the window skip template approval delays
  • Customer-started chats protect your quality rating and messaging limits
  • More inbound entry points means more service windows and lower blended cost

Common mistakes to avoid

The service window opens the door to free-form service messages — it does not make everything free. A marketing or utility template you send during a user-initiated window is still billed per delivered message at Meta's live rate-card price for that category, so a promotional broadcast is charged whether or not a window is open. Teams also assume the window lasts a fixed 24 hours from the first message, when in fact every new customer reply resets the clock. And the most expensive mistake is letting the window lapse: once 24 hours pass with no inbound message, you can no longer send free-form text and must fall back to an approved template to re-engage.

  • Sending a marketing template inside the window — still billed by category, per message
  • Treating the window as fixed rather than rolling with each customer reply
  • Letting the window expire, then trying to send free-form text (it will fail — use a template)
  • Assuming 'customer messaged first' means the whole conversation is free

Frequently asked questions

What is a user-initiated conversation on WhatsApp?+
It is any WhatsApp Business API conversation the customer starts — by messaging your number, tapping a click-to-WhatsApp ad, scanning a QR code, or clicking a wa.me link. Their first message opens a 24-hour service window in which your business can reply with free-form messages.
Is a user-initiated conversation free?+
The 24-hour service window it opens is free for free-form service replies — you are not charged per message for answering. But if you send a marketing, utility, or authentication template during that window, that template is still billed per delivered message at Meta's live rate for its category.
How is it different from a business-initiated conversation?+
A business-initiated conversation is one your company starts by sending a template to a customer who has not messaged you recently. A user-initiated conversation is one the customer starts. Only the customer-started version opens a free service window for free-form replies.
How long does the 24-hour service window last?+
It runs for 24 hours from the customer's last message and rolls forward every time they reply again. If 24 hours pass with no new inbound message, the window closes and you must use an approved template to re-open the conversation.
Did WhatsApp's move away from per-conversation billing change this?+
Yes. Since 1 July 2025 Meta bills per delivered message by template category rather than per conversation. The 24-hour window is now a free service window that governs when you may send free-form messages — it is no longer a billing unit itself.
Can I send a promotional message inside a user-initiated window?+
You can, but it must be an approved marketing template and it will be charged per delivered message at the marketing rate. The free service window only covers free-form service replies, not promotional or transactional templates.
How do I get more user-initiated conversations?+
Add inbound entry points: run click-to-WhatsApp ads, put WhatsApp QR codes on packaging and receipts, add wa.me links to your site and email footer, and prompt replies at the end of templates. Each customer-started chat becomes a free service window.
What happens when the service window expires?+
Once the window closes, WhatsApp blocks free-form messages to that customer. To re-engage you must send an approved utility, marketing, or authentication template, which is billed per delivered message by its category.
