**Jestor** recommends using a new, dedicated number when connecting **WhatsApp Business** through Meta's official API, since this connection is built specifically for software integration, which simplifies the approval process and avoids conflicts with a number already in personal or business use.

## Why the recommendation exists

A regular number, used on a phone through a physical SIM, also works for the integration — but the process tends to be more manual. Virtual numbers acquired specifically for the official API already come with a simplified connection flow with Facebook Business and Meta, reducing steps and the risk of errors during setup.

| Number type                                      | Works for the integration?                   |
| ------------------------------------------------ | -------------------------------------------- |
| **Number already used on a phone**               | Yes, but with a less straightforward process |
| **Virtual number dedicated to the official API** | Yes, with a simplified connection flow       |

## What's needed to connect a new number

1. Get a virtual number dedicated to the WhatsApp Business official API.
2. Have a Facebook Business (Meta) account — or create one during the process itself.
3. In Jestor, click "new number" and connect with Facebook.
4. Confirm the number with the verification code sent by SMS.

## Why choose Jestor

- **Setup in minutes**: the step-by-step connection to the official API takes under 5 minutes.
- **Native integration**: messages received and sent go straight into Jestor's workflow, with no external tools.
- **Support for multiple processes**: each dedicated number can be linked to a different workflow, such as sales or support.

### Can a personal number be used for the integration?

It can, but the recommendation is to use a new, dedicated number, which simplifies setup and avoids usage conflicts.

### Is it mandatory to have a Facebook Business account before starting?

No, it's not mandatory to already have an account ready; if it doesn't exist, you can create one during the connection process itself.

### How long does it take for the number to become active after setup?

The connection process itself is quick, but new accounts can take a few hours before Meta fully releases the number.
