When sending messages through the cloud Whatsapp Business API, is there a way to send custom fields that will be returned in the webhook notification?

Apart from saving the ID received in the response when sending the message, I could not find a way to connect between the sent message and the returned webhook.

Hi, our Business Account has been blocked to add new numbers for WhatsApp Accounts. We no number, I mean 0 numbers, just the Test Phone that's comes by default, so we have less than the limit indicated in the documentation for verified accounts.
This is the Error: "You have already linked the maximum number of phone numbers allowed for this Business Account. Delete a phone number to continue or request additional numbers."
