**[Jestor](https://jestor.com/?ref=blog.jestor.com)**'s recommendation is to use a new, dedicated number for the **WhatsApp Business** integration with the **official API**, although an existing number also works — a dedicated number avoids conflicts with any personal or business use that number already had.

## Why not just use a number that already exists?

A number already used in the regular WhatsApp app carries a history of conversations and previous settings. When migrating to the **official API**, that history isn't carried over the same way, and the number starts operating under the API's rules — including the 24-hour window for conversations outside of templates. A dedicated number starts out already configured for that logic, without inheriting expectations from prior use.

## What's needed to connect a number to Jestor?

1. A WhatsApp number, new or existing — a virtual API number is recommended.
2. A **Facebook Business** (Meta) account, which most people already running ads likely already have.
3. Follow Meta's own login steps inside **[Jestor](https://jestor.com/?ref=blog.jestor.com)**.
4. Wait for Meta's activation period, which usually takes a few hours for new accounts.
