How click to WhatsApp works
The ad looks like any other Facebook or Instagram ad, but its button opens WhatsApp rather than a web page. The thread appears with a first message already typed — something like an enquiry about the product in the ad — and the person only has to send it. Once they do, the conversation lands in your WhatsApp Business app, or in whatever tool is connected to your business number.
To run these ads you need a WhatsApp Business account attached to the Facebook Page and the number verified. That number becomes the destination, so it should belong to the business rather than to whoever happened to set the campaign up. When the person sends their first message you receive their WhatsApp number, which is a working contact detail rather than one copied from a profile.
A rule worth knowing before you start: once a customer’s conversation has been quiet for a while, what a business may send them changes, and proactive messages have to use approved templates instead of free text. Replying promptly is not only good manners, it keeps the thread open.
Why click to WhatsApp matters
The step from advert to conversation is shorter than any form can manage: no page load, no typing, no leaving the app people already have open. For audiences in the Gulf, India, and among Nepali communities abroad, WhatsApp is often where business is genuinely conducted, which makes these ads a natural fit for remittance, travel, education consultancy and anything sold through a quotation.
The contact detail you receive is also stronger than a form’s. Somebody who messages you from their own number has given you a channel they actually answer, and the thread stays in their history as a reminder that the conversation exists.
Common mistakes with click to WhatsApp
Assuming the audience is on WhatsApp is the first, and inside Nepal it is a real risk — plenty of local audiences message on Viber or Messenger instead, and an ad pointing at an app they rarely open will simply underperform. Check what your existing customers use before committing the budget.
The second is pointing the ad at a personal phone. When that person leaves, the conversations, the numbers and the history leave with them. The third is treating the chat list as a database: numbers sitting in a handset are not reportable, not shared with the sales team and not recoverable if the phone is lost.
How to act on it
Set up a business number with the WhatsApp Business API or the business app, depending on how many people need access, and make sure more than one person can reply. Rewrite the prefilled message so it names the specific thing the ad offered rather than saying hello; a specific opening tells you which advert produced the enquiry.
Answer while the person is still holding the phone, ask one qualifying question early, and copy the name, number and outcome into your sales system the same day. Then judge the campaign on conversations that became customers, not on threads opened. The page on WhatsApp and Messenger ads sets out how these campaigns are structured.
