If your webhooks aren't working as you expect, please check the following:

1. Note that webhooks are called before the node appears. 
2. Make sure the URL for your webhook is accessible; it must be able to be opened in a browser.
3. If you're not sure your webhooks are being called properly, check the Event Log (under Usage Reports, Event Log). Select the Webhook event type, and you can see if any errors are present.
