Why is a dedicated new number recommended for integrating WhatsApp Business with the official API?

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

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.
