🔐 What changed?
Meta updated WhatsApp two-factor authentication.
Previously, a 6-digit PIN was used.
Now, the new authentication requires an 8-character alphanumeric password; that is, it can contain letters and numbers.
This change may cause issues when connecting WhatsApp to the CRM.
DETAILS: The Coexistence connection is in BETA BY META, it may present instabilities and this is especially more true when changes like this PIN change occur.
📱 How to troubleshoot connection issues
If you have difficulty connecting:
Open WhatsApp Business on your mobile phone.
Access Settings.
Go to Account.
Access Two-factor authentication.
Disable two-factor authentication.
Wait approximately 5 minutes.
Then, go back to the CRM and connect again.
🔗 Connect WhatsApp again
During the connection:
If this number is already in the CRM and you only need to reconnect it or it is already in META, select your WhatsApp number; or
IF the selection of your number is disabled saying it is not qualified, type your number and proceed, it may be enabled, this unqualified error on this screen appears to be a META BUG. (See my attached video to understand better) or
Choose Connect a WhatsApp Business app.
Then, follow the instructions displayed on the screen.
⚙ CRM Configuration
In the CRM:
In the PIN field, if it is a new connection you can leave it blank and we create by default 123456. And if you are editing a connection, make sure it is filled in, it can also be keeping the default 123456.
Configure the connection name.
Make sure the three pieces of information below are filled in (phoneNumberId, Waba ID and Phone number), if they are not, log in again with Facebook.
Click Finish to save.
✅ Done! Wait for the connection to be completed.
Perform send and receive tests as well as sending already approved templates to ensure full operability of the connection.
