ChatsSyncWhat is the WhatsApp Business API?
The WhatsApp Business API (officially the WhatsApp Business Platform by Meta) lets businesses message customers on WhatsApp at scale. Unlike the normal app on one phone, the API connects your WhatsApp number to software, so many team members, chatbots and campaigns can work on the same number.
Meta does not provide a chat screen for the API. You use it through a platform such as ChatsSync, which gives your team an inbox, a chatbot builder, campaigns and reports.

What you need to use the WhatsApp API in Pakistan
- A Meta (Facebook) Business account for your business.
- A phone number that can receive an SMS or call for verification.
- Business details such as your business name, website or Facebook page — these help with business verification.
- A WhatsApp API platform such as ChatsSync to manage chats, bots and campaigns.
Message templates and the 24-hour window
When a customer messages you, a 24-hour customer service window opens. Inside it you can reply freely with any message — text, images, documents or chatbot replies.
To message a customer first, or after the 24 hours have passed, you must use a message template approved by Meta. Templates have categories such as marketing (offers and promotions), utility (order updates, reminders) and authentication (one-time codes).
ChatsSync shows when the window has closed and lets you pick an approved template in one click. Its template builder previews the message exactly as the customer will see it.
How Meta charges for the WhatsApp API
Meta charges businesses per delivered template message, with the price depending on the template category and the customer’s country. Replies inside the 24-hour customer service window are free. Meta updates its rates from time to time, so check Meta’s official WhatsApp Business pricing page for the latest numbers.
The ChatsSync subscription is separate: Rs 5,000 for 1 month, Rs 12,500 for 3 months or Rs 40,000 for 1 year. See ChatsSync pricing.
