Configuring webhook NQL conditions
Write a query for the NQL conditions field of a webhook using:
NQL tables and NQL properties supported by Webhooks.
NQL operators supported by Webhooks.
NQL tables supported by Webhooks
Find below the NQL tables supported by Webhooks in the format of <namespace>.<table>.
The system displays an error message when saving a webhook configuration with unsupported NQL objects in the NQL conditions field, even for valid syntaxes.
alert.alerts
campaign.responses
execution.crashes
device_performance.boots
device_performance.system_crashes
device_performance.hard_resets
remote_action.executions
sessions
NQL properties supported by Webhooks
When writing the query in the NQL conditions field from the webhook configuration page, the system displays the supported NQL properties from the NQL objects listed above. See the image below.
NQL operators supported by Webhooks
Not all NQL operators are available to the customer. When working with punctual events, use the following subset of NQL operators.
where
selection
Yes
No
list
projection
Yes
Yes, at least once.
and
filtering
Yes
No
or

No
You must add every NQL field you use as a placeholder in the webhook Resource or Payload to the list clause.
Even if you do not use any placeholders, still you must add one NQL field to the list clause.
