Couldn't sync the business details. Facebook API Error (400): Unsupported get request.

Hi Team,

I’m suddenly getting the following error in Pabbly Chatflow when trying to sync the business details:

“Couldn’t sync the business details. Facebook API Error (400): Unsupported get request. Object with ID '976856392176089' does not exist, cannot be loaded due to missing permissions, or does not support this operation.”

Everything was working fine until a couple weeks back, and I haven’t made any changes to the setup. Could you please check what might be causing this and let me know how I can fix it?

Thanks!

Hello Manuj,

Thanks for reaching out and sharing the exact error.

This Facebook API Error (400) - "Object with ID does not exist, cannot be loaded due to missing permissions, or does not support this operation" - typically means the required Meta/Facebook permissions were not fully granted or Meta has revoked/updated the permission tokens between your Facebook Business Manager and Pabbly Chatflow. This can happen even if you haven't made any changes on your end.

To resolve it, please reconnect your WhatsApp number (do NOT delete it):

1. Go to your Pabbly Chatflow Dashboard and click Add WhatsApp Number.
2. Click WhatsApp Connect and click through Next, Next, Next in the Facebook embedded signup flow, making sure to grant ALL permissions on every screen (do not uncheck any permission toggle).
3. At the registration step, choose the correct option based on your number type: if it is a WhatsApp Business App number (previously used in the WhatsApp Business mobile app), click Subscribe; if it is a fresh/Cloud API number, click Register.
4. After reconnecting, try Sync again - it should now succeed.

Reconnecting re-authorizes Meta permissions and refreshes the access token while preserving all your existing settings and data.

If the error still appears after reconnecting and syncing, please share the exact error from the dashboard (a screenshot is helpful) so we can investigate further.
