You are all set !
Webhooks
In your ServiceNow instance, go to System Definition > Business Rules.
Select New.
Give your new Business Rule a descriptive name, choose what table you want it to trigger on, and check the Advanced box.
Next, choose After for when you want it to run. You may also choose to add filter conditions, but we want it to trigger for all incident tickets in this example. Also, for this example, we want to select Insert because we want it to trigger when a new incident ticket is created.
Navigate to the Advanced tab. In the Script editor, add the following code. Make sure to replace <insert webhook public URL> with whatever the webhook target is. The target URL may be a web server that will parse and use the data or another service that accepts incoming webhooks.
Lastly, replace the <secret> field with the sercret key of your webhook API.
