Key takeaways
- The number belongs to your community, in your own WhatsApp Business Account, not to Milvao.
- Use a new number that isn't on the WhatsApp or WhatsApp Business app. It works with one platform at a time.
- Milvao needs the account ID and a permanent system user token. The token is encrypted and never shown again.
- Four message templates let Milvao write first, for example to offer a request outside the 24-hour window.
- A one-click Connect with Facebook option is planned, waiting for Meta's approval.
What the WhatsApp Business Platform is
The WhatsApp Business Platform is Meta's way for businesses and software to send and receive WhatsApp messages programmatically, through the Cloud API. Meta's documentation describes business phone numbers used for sending and receiving, webhooks that deliver incoming messages and delivery updates to the business's server, and message templates that generally need approval and are the only messages a business can send outside the customer service window.
It is different from the WhatsApp Business app on a phone. A number on the platform is answered by software or a team, not from one handset, which is why Milvao asks for a number that isn't used in either app.
Connect your number to the WhatsApp Business Platform
Setting it up takes about 30 minutes in Meta's business tools, then one click in Milvao. The Help Center has the full walkthrough in Connect your WhatsApp number.
- 1Choose a new number that isn't on WhatsApp or the WhatsApp Business app and can receive an SMS or voice call.
- 2In Meta's Business settings, create a WhatsApp Business Account under your community's own business portfolio and verify the number.
- 3Request access to Milvao's app ID in Business settings, under Apps. Milvao approves the request, usually within a working day.
- 4Create a system user, assign it Milvao's app and your WhatsApp account, and generate a token that never expires with the two WhatsApp permissions.
- 5Copy your WhatsApp Business Account ID from Business settings, under WhatsApp accounts.
- 6In Milvao, open Settings, WhatsApp number, paste the ID and token, and click Check connection.
Check connection saves nothing until the token works and the number belongs to the account. After a passing check the number moves to Testing, Milvao staff confirm a reply reaches you, and then switch it to Active.

Message templates Milvao uses
WhatsApp only lets a business start a conversation, or write more than 24 hours after a member's last message, with a template Meta has approved. Milvao submits four in the Utility category: Introduction offer, Contact disclosure, Request update and Profile link. The Help Center shows their exact wording. The WhatsApp 24-hour window entry explains the rule.
What it costs
Meta charges for some messages on your WhatsApp Business Account, per message, and bills them to the payment method you add in WhatsApp Manager. Those charges are separate from Milvao's plans. Milvao's own pricing is a 30-day pilot for ₹4,999, then Starter at ₹2,999 a month.
