   DENY AN INCOMING REQUEST IN CYBERARK
   CREATED BY: Vadim Melamed, EMAIL: vpasmodule@gmail.com
.DESCRIPTION
   USE THIS FUNCTION TO DENY AN INCOMING REQUEST IN CYBERARK
.LINK
   https://vpasmodule.com/commands/Deny-VPASIncomingRequest
.PARAMETER token
   HashTable of data containing various pieces of login information (PVWA, LoginToken, HeaderType, etc).
   If -token is not passed, function will use last known hashtable generated by New-VPASToken
.PARAMETER RequestedSafe
   Safe name that will be used to query for the target account if no AcctID is passed
.PARAMETER RequestedUsername
   Username that will be used to query for the target account if no AcctID is passed
.PARAMETER RequestedPlatform
   PlatformID that will be used to query for the target account if no AcctID is passed
.PARAMETER RequestedAddress
   Address that will be used to query for the target account if no AcctID is passed
.PARAMETER RequestedAcctID
   Unique ID that maps to a single account, passing this variable will skip query functions to find target account
.PARAMETER RequestedReason
   Reason that will be used to query and find the target account request
.PARAMETER requestID
   Unique ID that maps to a single account request, passing this variable will skip any query functions
.PARAMETER denyReason
   Reason for denying the incoming request, will be saved for audit purposes
.PARAMETER WhatIf
   Run code simulation to see what is affected by running the command as well as any possible implications
   This is a code simulation flag, meaning the command will NOT actually run
.PARAMETER HideWhatIfOutput
   Suppress any code simulation output from the console
.PARAMETER InputParameters
   HashTable of values containing the parameters required to make the API call
.EXAMPLE
   $DenyIncomingRequestStatus = Deny-VPASIncomingRequest -RequestedSafe {SAFE VALUE} -RequestedPlatform {PLATFORM VALUE} -RequestedUsername {USERNAME VALUE} -RequestedAddress {ADDRESS VALUE} -denyReason {REASON VALUE}
.EXAMPLE
   $DenyIncomingRequestStatus = Deny-VPASIncomingRequest -RequestedAcctID {ACCTID VALUE} -requestID {REQUESTID VALUE} -denyReason {REASON VALUE}
.EXAMPLE
   $WhatIfSimulation = Deny-VPASIncomingRequest -RequestedAcctID {ACCTID VALUE} -requestID {REQUESTID VALUE} -denyReason {REASON VALUE} -WhatIf

        RequestedUsername = "TargetUsername"

        RequestedReason = "Vadim request this account to test for a demo"
        denyReason = "Vman denied this request"
        WhatIf = $true|$false
        HideWhatIfOutput = $true|$false
   }
   $DenyIncomingRequestStatus = Deny-VPASIncomingRequest -InputParameters $InputParameters
.EXAMPLE
   $InputParameters = @{
        RequestedAcctID = "22_123"
        RequestedReason = "Vadim request this account to test for a demo"
        denyReason = "Vman denied this request"
        WhatIf = $true|$false
        HideWhatIfOutput = $true|$false
   }
   $DenyIncomingRequestStatus = Deny-VPASIncomingRequest -InputParameters $InputParameters
.EXAMPLE
   $InputParameters = @{
        requestID = "123_4"
        denyReason = "Vman denied this request"
        WhatIf = $true|$false
        HideWhatIfOutput = $true|$false
   }
   $DenyIncomingRequestStatus = Deny-VPASIncomingRequest -InputParameters $InputParameters
.OUTPUTS
   $true if successful
