Connect Meta’s official WhatsApp Business Platform without leaving the app

The WhatsApp Business Platform is Meta’s offering for medium and large businesses that message customers at scale through programmatic access, using the Meta-hosted Cloud API. The WhatsApp Business app is a free phone app for small businesses with limited integration (WhatsApp Business FAQ).

A QR-linked number in whatsappx.si uses WhatsApp’s linked-device feature, like WhatsApp Web: the account still lives on a phone, up to four devices can be linked at a time, and linked devices log out if the phone is unused for more than 14 days (WhatsApp help).

An official platform number differs in ways that matter for a team:

• No phone in the loop. The number is registered with Meta’s Cloud API, so there is no primary phone to keep online and no linked-device cap.
• Message templates. Outside a customer service window, templates are the only message type a business can send. The window is a 24-hour timer that starts when a customer messages you and resets each time they do (Meta documentation).
• Messaging limits and quality rating. Meta caps how many unique users a business portfolio can message outside the window in a moving 24-hour period; new portfolios start at 250 and can scale up (Meta documentation). Each number also carries a quality rating based on feedback such as blocks and reports (Meta Business Help).
• Official Business Account badge. Platform numbers can apply for the blue checkmark after meeting Meta’s requirements, including Business Verification and at least 30 days on the platform (Meta documentation).

Both connection types land in the same shared inbox, so a team can start with a QR-linked number today and add official numbers later.

A message template is a pre-built message stored in your WhatsApp Business Account. Meta reviews each template before it can be sent, and review can take up to 24 hours (Meta documentation).

Templates fall into three categories, each priced differently by Meta: marketing, utility and authentication. Utility templates must be non-promotional and specific to, or requested by, the customer, such as an order update or appointment reminder. Only authentication templates may carry one-time passcodes (Meta documentation).

In whatsappx.si you create a template with its name, category and language, and sync your templates with Meta. The template list shows the status Meta reports back, so your team can see which templates are approved. For example, a clinic could draft a utility template for appointment reminders, check in whatsappx.si when Meta has approved it, and keep using free-form replies inside the 24-hour window for everyday questions.

Two separate parties. Meta bills the per-message fees to the payment method on your business portfolio. whatsappx.si bills your software subscription, which never includes Meta’s messaging fees.

Two regional points matter. In India, Meta launched INR billing on January 1, 2026; businesses whose Sold-To country is India must migrate every WhatsApp Business Account in their portfolio to INR by December 31, 2026, or Meta will stop delivering their messages from January 1, 2027. In every market, Meta offers lower utility and authentication rates at higher monthly volume, and opens a free entry point window when a customer arrives from a Click-to-WhatsApp ad (Meta documentation).

Because rates change and vary by market, whatsappx.si does not publish Meta’s numbers. Check Meta’s rate cards and your Meta billing dashboard for what you actually pay.

Choose the official WhatsApp Business Platform when you need Meta’s sanctioned route for higher volume, want approved message templates (Meta’s only way to reach customers outside the 24-hour window), run several numbers in one workspace without keeping several phones online, connect your own systems through the whatsappx.si REST API and webhooks, or want a path to the Official Business Account badge.

Stay with a QR-linked number when you want to keep the number you already use with its recent chat history, your volume is conversational (mostly replies to people who message you first), or you are getting started and want the team in one inbox today.

Whichever route you take, treat the number carefully. If you create a brand-new WhatsApp number for QR linking, use it normally from your phone for 15–20 days before you connect it. Send in small batches of 5–10 messages at a time, never bulk blasts, and only to people who have agreed to hear from you. WhatsApp’s terms prohibit bulk and automated messaging, and WhatsApp may restrict or block a number that breaks them (WhatsApp help). The official platform is Meta’s sanctioned route for higher volume and templates, but its messaging limits, quality rating and Business Messaging Policy still apply.
