Hello, 

In that case, you need to develop a custom method for the webhook and you need to call that method based on CURD operations.

Eg. code

    @api.model
    def create(self, vals):
        record = super(MyModel, self).create(vals)
        self.send_webhook_notification('create', record)
        return record

    def write(self, vals):
        res = super(MyModel, self).write(vals)
        self.send_webhook_notification('update', self)
        return res

    def unlink(self):
        res = super(MyModel, self).unlink()
        self.send_webhook_notification('delete', self)
        return res

    def send_webhook_notification(self, action, record):
        # Construct webhook payload
        payload = {
            'action': action,
            'record_id': record.id,
            'record_name': record.name,
            # Add more fields as needed
        }

        # Send webhook request
        webhook_url = 'https://your-webhook'
        requests.post(webhook_url, json=payload)

Thanks
