Why is it recommended to use a new dedicated number to connect WhatsApp Business to the official API?

Jestor'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?

A WhatsApp number, new or existing — a virtual API number is recommended.
A Facebook Business (Meta) account, which most people already running ads likely already have.
Follow Meta's own login steps inside Jestor.
Wait for Meta's activation period, which usually takes a few hours for new accounts.

Requirement	Note
Number	New is recommended; existing also works
Facebook Business account	Required to authenticate via the official API
Setup time	Under 5 minutes, plus Meta's activation time

Why choose Jestor?

Connecting via the official API for WhatsApp inside Jestor is simple and secure, with Meta's login steps guided directly on the platform — no need to leave the system to configure anything manually.
