Hello Pabbly Support,

We need help connecting an existing WhatsApp Business mobile app number to Pabbly Chatflow through Coexistence, while retaining the mobile app and existing chats.

Steps followed:
1. Add WhatsApp Number > WhatsApp Connect.
2. Select a number currently active on the WhatsApp Business app.
3. Choose Connect without a catalog.
4. Continue with Facebook.

Expected: the option to connect the existing WhatsApp Business app and pair it with Chatflow.
Actual: Meta opens the phone-number-first signup. Its dropdown only offers creating a new number or using a virtual number. Entering our existing number returns Meta error 2494064: the phone number is already registered on WhatsApp and must be disconnected.

We have not deleted or disconnected our WhatsApp account. Please investigate whether the correct coexistence signup configuration is being applied and whether our account/number is eligible, and provide a supported way to connect without losing chats or interrupting the WhatsApp Business mobile app. We do not authorize deleting, migrating, or disconnecting that existing account.

A contact-form request has also been submitted from this account, but its confirmation directed technical questions to this forum. The affected number is provided in the private field below. Please use a private secure channel if further account-specific diagnostics are needed.

Thank you,
Murix Supply

Hello Pabbly Support,

Following your email response, here are the requested details:

1. The affected number has been used in the WhatsApp Business mobile app for approximately eight months and is actively used.

2. To the best of the owner’s knowledge, it has never been connected to another BSP, WhatsApp API, or automation platform. This is not independently verified, so please check for any existing or residual association on Meta’s side.

The requirement is to keep using this same number from the WhatsApp Business mobile app while running order notifications through Chatflow. Please have a support specialist review the coexistence eligibility and the embedded signup configuration, and advise on the next supported step. We do not want to delete or disconnect the WhatsApp Business account.

Please provide a private upload link if you need a screen recording of the dropdown and onboarding steps. The account and affected number were already supplied privately in the support request.

Thank you,

Murix Supply
