Hi everyone, I have a **lead qualification chatbot that contacts new leads via WhatsApp. **Recently, I discovered that for around two months, WhatsApp messages were not being sent because of a payment issue in the WhatsApp Business account (an expired card), leading to many lost leads. I understand that managing the WhatsApp Business account and payment details is my responsibility and a whole other issue, but I wish there was a way in Botpress to automatically detect if WhatsApp messages were failing. I have already implemented an external API that validates WhatsApp numbers before sending messages, so I can confirm whether a phone number is connected to WhatsApp. However, I have not found a way to automatically verify whether the message was actually sent and delivered successfully. I know that the logs show this information, but I am looking for a more automated solution, for example: * A way for Botpress to trigger an event when a WhatsApp message fails to send * A delivery status callback/webhook integration * A built-in monitoring mechanism for WhatsApp channel issues (such as expired payment methods or disconnected accounts) Is there currently a way to automatically check whether WhatsApp messages were sent and delivered, rather than manually reviewing logs? Thanks! PS: Here's the error-message I was getting in the logs:

[whatsapp] WhatsApp message delivery failed. Message ID: ###, Recipient: ###, Errors: Business eligibility payment issue: Business eligibility payment issue - Message failed to send because your WhatsApp Business account has unsettled payments. Visit https://business.facebook.com/... to resolve this issue.

you can use a hook to read before incoming to read the incoming message and identify if there are payment related errors then trigger and email - I haven't tested this myself but i am sure this can be done

Thank you for the hint. I am, however, not sure if the hook "before incoming" is catching error messages in the logs. It appears that it only catches events originating from a user. https://botpress.com/docs/studio/concepts/hooks

[that is for ](https://botpress.com/docs/studio/concepts/hooks#before-incoming)

I just tested it by creating a new "before incoming" hook and logging every event to the console. I found that it did trigger for webhook events that are configured in the workflow, but it did not catch 2 WhatsApp error messages that occurred during this test and are otherwise visible in the logs. So, it appears that using a "before incoming" hook will not be possible for this problem.
