Function Get-AtwsContactWebhookExcludedResource
{


<#
.SYNOPSIS
This function get one or more ContactWebhookExcludedResource through the Autotask Web Services API.
.DESCRIPTION
This function creates a query based on any parameters you give and returns any resulting objects from the Autotask Web Services Api. By default the function returns any objects with properties that are Equal (-eq) to the value of the parameter. To give you more flexibility you can modify the operator by using -NotEquals [ParameterName[]], -LessThan [ParameterName[]] and so on.

Possible operators for all parameters are:
 -NotEquals
 -GreaterThan
 -GreaterThanOrEqual
 -LessThan
 -LessThanOrEquals

Additional operators for [string] parameters are:
 -Like (supports * or % as wildcards)
 -NotLike
 -BeginsWith
 -EndsWith
 -Contains

Properties with picklists are:


Entities that have fields that refer to the base entity of this CmdLet:


.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.ContactWebhookExcludedResource[]]. This function outputs the Autotask.ContactWebhookExcludedResource that was returned by the API.
.EXAMPLE
Get-AtwsContactWebhookExcludedResource -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsContactWebhookExcludedResource -ContactWebhookExcludedResourceName SomeName
Returns the object with ContactWebhookExcludedResourceName 'SomeName', if any.
 .EXAMPLE
Get-AtwsContactWebhookExcludedResource -ContactWebhookExcludedResourceName 'Some Name'
Returns the object with ContactWebhookExcludedResourceName 'Some Name', if any.
 .EXAMPLE
Get-AtwsContactWebhookExcludedResource -ContactWebhookExcludedResourceName 'Some Name' -NotEquals ContactWebhookExcludedResourceName
Returns any objects with a ContactWebhookExcludedResourceName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsContactWebhookExcludedResource -ContactWebhookExcludedResourceName SomeName* -Like ContactWebhookExcludedResourceName
Returns any object with a ContactWebhookExcludedResourceName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsContactWebhookExcludedResource -ContactWebhookExcludedResourceName SomeName* -NotLike ContactWebhookExcludedResourceName
Returns any object with a ContactWebhookExcludedResourceName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
