Hello,
Thanks

I need a step to check if a Whatsapp number is valid or not.
I tried with API by Pabbly but I receive always the same error despite IDs are verified:

Unsupported post request. Object with ID 'XXXX' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api

Is there any way to make this happen without using a 3rd party app?

Thank you

Hello this is the workflow, even if I just tried, it is not a Pabbly error or bug.
I just ask a way to do the task.

Hello @sportinvest.org,

Thank you for sharing the workflow URL.

Currently, there’s no Meta API to verify phone numbers. On WhatsApp, you can only check by attempting to start a chat — if the number isn’t registered, it prompts an invite.

Regarding your error, it indicates that the Portfolio ID or Account ID used doesn’t exist, isn’t accessible, or lacks permissions:

“Unsupported post request. Object with ID '709655225574784' does not exist, cannot be loaded due to missing permissions, or does not support this operation.”

Please verify the ID and ensure your account has the required permissions.

Is there any alternative?
