WhatsApp Business API in Malaysia: a plain guide

WhatsApp has three versions. Ordinary WhatsApp is for people. The WhatsApp Business app is a free app for small businesses, with a business profile, labels, a catalogue and simple automatic messages, run from one phone and a few linked devices. The WhatsApp Business Platform, which most people still call the WhatsApp Business API, has no app of its own: it is a connection that lets software send and receive messages on your number.

The platform is what you need when a chatbot should answer customers, when several staff share one number through a helpdesk, or when your system should send order updates. Meta hosts it through the Cloud API, so you do not run any servers yourself.

Any legitimate business that follows WhatsApp's Business Messaging Policy and Meta's Commerce Policy can use the platform, from a single shop to a large company. You do not need a special licence, and a Malaysian company or sole proprietor can sign up in the same way as a business anywhere else.

What Meta does check is the number of different people you can message first. A new business portfolio starts with a limit on business-started conversations, and completing Meta's business verification is one way to raise it (Meta's “Messaging limits” page, checked November 2026). Replies to customers who wrote to you inside the 24-hour window do not count against that limit.

Meta's Embedded Signup page (checked November 2026) describes what a business does when a provider connects it: choose or create a business portfolio, choose or create a WhatsApp account, enter and verify a business phone number, and enter a display name. The flow creates the WhatsApp assets for you, and the business owns them.

We do not list Meta's rates here because Meta sets and changes them; check Meta's own rate card. What matters is how the charge is worked out, because that decides what your bill looks like. All points below are from Meta's WhatsApp pricing pages, checked November 2026.

When a customer messages you, a 24-hour customer service window opens, and each new message from the customer restarts it. Inside that window your software can send any normal reply: text, images, links and buttons. This is where a customer-service chatbot does its work.

Outside the window, the only way to message a customer is a template: a message written in advance, sorted into marketing, utility or authentication, and approved by Meta before you can send it (Meta's “Template fundamentals” page, checked November 2026). Order updates and appointment reminders are typical templates.

Gydr uses Meta's Embedded Signup. In the Gydr dashboard you open Channels, click Connect Channel, choose WhatsApp and click Continue with Facebook. You sign in, pick your business and number, and Meta creates the connection. There is no token to copy, and the WhatsApp account stays in your own Meta business portfolio, so Meta bills you directly and Gydr does not add a mark-up on Meta's fees.

If you already use the WhatsApp Business app, you can connect that same number and keep using the app, with the conditions Meta sets. Gydr then answers inside the 24-hour window from your own knowledge, writes one complete message per reply to keep Meta charges predictable, and holds replies for up to three days if the window has closed, sending them when the customer writes again. Gydr does not send templates or broadcasts.

Many companies resell access to the platform. Compare them on these points rather than on a headline price, and ask each one to show you the answer in writing.
