One number per session

One WhatsApp number links to one session in the workspace. And once a session is linked to a number, it doesn’t accept another one. Together, the two rules stop the same chats from arriving twice.

Rule 1: one number, one session

WhatsApp lets you link a number to several devices, but Corteksa stops it from being linked to 2 sessions in the same workspace. Otherwise the team would get the same chats twice, and 2 people would reply to them.

When the code is scanned with a number that’s already in use, the number is disconnected straight away, the session goes back to Scan QR, and the person linking it gets a notification such as “The number 966512345678 is already linked to the Sales session. Scan with a different number.” The disconnection is recorded in the activity log.

When someone asks for a pairing code for a number that’s already in use, the request is refused straight away, with the name of the session that has the number.

Another workspace can link the same number. And deleting a session frees its number.

Rule 2: a session keeps its number

After the first link, the session remembers its number. If it’s logged out and the code is then scanned with a different number, the scan is refused and the new number is disconnected. The session’s members get a notification, and the person who scanned gets a Wrong number scanned notification.

To link a different number, create a new session.

WhatsApp Cloud and Meta channels

An account or number that’s linked in another workspace is refused, because one account belongs to one workspace only.

If something goes wrong

What you see
Why
What to do
“This number is already linked to the session ...”
The number is working in another session.
Use the existing session and add yourself as a member, or delete it first.
The scan is refused with a Wrong number scanned notification
The session was linked before to another number.
Scan with the original number, or create a new session for the new number.

A real example

Namaa Academy
The situation

A new employee tried to link the sales number to a second session, so he could see the chats on his own account.

What they did
  1. The scan was refused, and he got a notification with the name of the existing session.
  2. The manager added him as a member of the existing session instead.
The result

The number stayed in one session, and the employee now sees the chats his permissions allow.

A made-up company, to show the idea. The numbers are rounded.

Good to know

Sessions that shared a number before this rule was introduced stay as they are, and aren’t disconnected.
