Quick answer
Click-to-WhatsApp ads are Facebook and Instagram ads that open a WhatsApp chat with your business instead of a website or form. To run one, connect your WhatsApp number to your Facebook Page, create a campaign in Meta Ads Manager, choose Messaging apps → WhatsApp as the conversion location, and set a greeting for people who tap the ad. When a customer messages you from the ad on the WhatsApp mobile app and you reply, Meta opens a free entry point window in which your messages to that customer are not charged.
Most people in India would rather send a WhatsApp message than fill in a form or call a stranger. Click-to-WhatsApp ads use that habit: someone sees your ad, taps once, and lands in a chat with your business with a message ready to send. This guide covers what you need, how to set the ad up step by step, what to reply, what it costs and how to measure results.
How Click-to-WhatsApp ads work
1
A customer sees your ad on Facebook or Instagram, with a "Send WhatsApp message" button.
2
They tap the button and WhatsApp opens a chat with your business, often with a message already typed.
3
They send the message, and you reply with a greeting, questions or options.
4
You qualify and convert the lead in the chat, and keep their number for follow-ups.
Why businesses use Click-to-WhatsApp ads
- No form to fill. The customer only taps and sends, so more people who are interested actually reach you.
- A real conversation. You can answer questions, share prices, photos or a brochure, and book a visit in the same chat.
- You get a verified phone number. Every lead comes with a working WhatsApp number, not a mistyped one from a form.
- Works for most industries: real estate site visits, course admissions, clinic appointments, e-commerce product questions, new broadband connections, gym trials and more.
What you need before you start
- A Facebook Page for your business, and an Instagram account linked to it if you want Instagram placements.
- A Meta ad account with a payment method.
- A WhatsApp number connected to your Facebook Page. This can be a WhatsApp Business app number or a WhatsApp Business API number.
- A plan for replies. Ads can bring many chats at once. Decide who will reply, and set up automatic first replies.
| WhatsApp Business app | WhatsApp Business API | |
|---|---|---|
| Best for | Small budgets and a few chats a day | Regular ads and many chats a day |
| Who replies | You, from the phone and linked devices | Your whole team from a shared inbox, plus chatbot flows |
| Automation | Greeting and away messages | Chatbots, lead qualification, assignment to agents |
| Follow-ups | Manual | Approved templates and scheduled campaigns |
How to create a Click-to-WhatsApp ad in Ads Manager
Meta updates Ads Manager often, so labels may look slightly different in your account. The flow stays the same.
Create a campaign and choose an objective
In Ads Manager, click Create. Pick the objective that matches your goal: Engagement for more conversations, Leads to find people likely to share details, or Sales if you sell through chat.
Set the conversion location to WhatsApp
At the ad set level, choose Messaging apps as the conversion location, select WhatsApp, and confirm the WhatsApp number connected to your Page.
Choose your audience, placements and budget
Target the cities or pin codes you serve, the right age group and interests. Keep Facebook and Instagram placements on unless you know one works better. Start with a daily budget you are comfortable testing for at least a week.
Create the ad
Add an image, video or carousel, a short primary text and a headline. Use the Send WhatsApp message button. Say clearly what the customer gets by messaging you: a price list, a free consultation, a site visit or an offer.
Set the message template
In the ad's message settings, write the greeting people see and the pre-filled message or questions they can tap to start the chat. This makes the first message effortless.
Publish and let it run
Meta reviews the ad before it goes live. WhatsApp recommends running an ad for at least seven days for best results, so judge it after a full week, not after one day.

What Click-to-WhatsApp ads cost
There are two separate costs:
- Ad spend, paid to Meta. You set the budget in Ads Manager.
- WhatsApp messages, if you use the WhatsApp Business API. When a customer messages you from a Click-to-WhatsApp ad on the WhatsApp Android or iOS app and you reply within the 24-hour customer service window, Meta does not charge that reply and opens a free entry point window. While it is open, Meta does not charge for your marketing, utility, authentication or service messages to that customer. Meta's pricing page currently says this window can stay open for up to 7 days. Chats that start from the desktop or web versions of WhatsApp do not qualify.
Outside the free window, normal per-message rates apply. On QuickMessage, a marketing message to an Indian number costs ₹0.96 and a utility message ₹0.18, excluding GST. See how Meta charges work and our pricing. Source: Meta's WhatsApp pricing documentation.
How to measure results
- Cost per conversation from Ads Manager tells you how much each new chat costs.
- Cost per qualified lead or sale matters more. Tag chats in your inbox as hot, cold or converted, and compare with ad spend.
- Know which ad each chat came from. On the WhatsApp Business API, the first message from an ad carries details of that ad (Meta calls this the referral), so leads can be tagged by ad.
- Test one thing at a time: a different image, offer or audience, for at least a week each.
Common mistakes
Slow replies
A lead who waits hours goes to a competitor. Use an instant automatic first reply.
A vague ad
"Contact us" gets curious clicks. "Get the price list" or "Book a free trial" brings people who want something.
One phone for everything
If many chats arrive at once, one person on one phone cannot keep up. Share the load with a team inbox.
No follow-up
Many leads do not decide in the first chat. Ask if they would like updates, then follow up with approved templates. See lead nurturing on WhatsApp.
Want people to reach you on WhatsApp without ads too? Add a WhatsApp link or QR code to your website, bills and store. And before sending marketing messages later, make sure you have the customer's permission; see our opt-in guide.
Frequently asked questions
What is a Click-to-WhatsApp ad?
It is a Facebook or Instagram ad with a button that opens a WhatsApp chat with your business, so interested people can message you directly instead of visiting a website or filling in a form.
Do I need the WhatsApp Business API to run Click-to-WhatsApp ads?
No. You can use a WhatsApp Business app number connected to your Facebook Page. The API helps when many chats come in, because your team can reply from a shared inbox and a chatbot can handle first replies.
Are WhatsApp messages free for chats from Click-to-WhatsApp ads?
On the WhatsApp Business API, when a customer messages you from a Click-to-WhatsApp ad on the WhatsApp mobile app and you reply within 24 hours, Meta opens a free entry point window in which your messages to that customer are not charged. Meta's pricing page currently says it can stay open for up to 7 days. Ad spend is charged separately.

Choose Engagement for more conversations, Leads to find people likely to share their details, or Sales if you sell through chat. Then set the conversion location to Messaging apps and select WhatsApp.

At least seven days, which is what WhatsApp recommends for best results. Judge it on cost per qualified lead, not only cost per conversation.
