Jim, The process I use is working well for updating the meta column in ServiceNow from keywords in AppPortal.    ServiceNow's meta column takes a coma delimited string so it was very easy to implement.  I then create a JSON object of values I want to update in ServiceNow and pass to a pi/now/table/x_fls_appportal_import_service.  Your sync process provided a great starting point for understanding how this worked. I first created a web service that can be called from PowerShell.  The web service script is based on the web service created to synchronize catalog images but was modified to also get the keywords as well as custom variables we need to keep synchronized.   This query gets all items that were updated in ServiceNow within the past 70 minutes.  You could probably imbed the SQL into the PowerShell but I have other functions in the web service that I needed for other work.     SELECT DISTINCT pkgs.PackageTitle AS CatalogTitle, stuff((SELECT ',' + WD_WebPackageKeyword.KeyWord FROM WD_WebPackageKeyword WHERE WD_WebPackageKeyword.PackageID_FK = pkgs.PackageID FOR XML PATH('')), 1, 1, '') AS [Keywords], psnc.ServiceNowCatalogId AS ServiceNowCatalogId, psnc.UpdatedOn, pkgs.PackageID AS AppPortalPackageID, pkgs.[ImagePath] FROM vSearchCatalog pkgs JOIN [dbo].[WD_Package_SNCatalog] psnc ON psnc.[PackageID_fk] = pkgs.PackageID WHERE psnc.Info NOT IN ('Deleted') AND DATEDIFF(MINUTE, psnc.[UpdatedOn], SYSDATETIME()) < 70 AND pkgs.PackageTitle NOT IN ('Template Freeware', 'Template Licensed');     The next step was to create a PowerShell script that calls web service and iterates through items that were updated in ServiceNow in past 60 minutes and create a JSON object that gets passed to ServiceNow REST API.     # Iterate through the recently synced catalog items and upload their "Keywords" to the "meta" field. ForEach ($CatalogItem in $UpdatedCatalogItems) { Try { #Build JSON object of vields to update in ServiceNow. $json = new-object -TypeName PSObject $json | Add-Member -Type NoteProperty -Name 'meta' -Value $($CatalogItem.keywords) $json | Add-Member -Type NoteProperty -Name 'ap_packageid' -Value $($CatalogItem.AppPortalPackageID) $bodyJson = $json | ConvertTo-Json # Build result string $result = "Update ServiceNow '$($CatalogItem.CatalogTitle)' (Updated in AppPortal on: $($CatalogItem.UpdatedOn)) (PackageID: $($CatalogItem.AppPortalPackageID)) meta='$($CatalogItem.keywords)'" # Call function to update ServiceNow. if ((UpdateSnCatalogField $($CatalogItem.ServiceNowCatalogId) $bodyJson)) { $result += ": SUCCESS" $updateCount += 1 } else { $result += ": FAILED" $failCount += 1 } Log($result) } Catch [System.Exception] { $errMsg = "EXCEPTION when calling UpdateSnCatalogField function... $($_.Exception) ServiceNowCatalogId: $($CatalogItem.ServiceNowCatalogId), Meta: $($CatalogItem.Keywords) " LogError($errMsg) } }     The function below would was called during the iteration of updated catalog items to call ServiceNow's REST API,  api/now/table/x_fls_appportal_import_service     function UpdateSnCatalogField([string]$snCatId, $bodyJson) { # Change the Content-Type header to JSON # Set headers for ServiceNow Attachment API call $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]" $headers.Add('Authorization', "Basic $SCRIPT:snAuth") $headers.Add('Accept', 'application/json') $headers.Add('Content-Type', 'application/json') $method = "POST" if ($GLOBAL:debugLogging) { Log ("BodyJson=($bodyJson)") } # Send HTTP request $response = Invoke-WebRequest -UseBasicParsing -Headers $headers -Method $method -Uri $SCRIPT:serviceNowAppPortalImportServiceURL -Body $bodyJson # Check response status if ($response.StatusCode -eq 201) { #success if ($GLOBAL:debugLogging) { Log ("Set $snFieldName value to ($snFieldValue) for catalog item ($snCatId)") } } else { LogError("Failed to set $snFieldName value to ($snFieldValue) for catalog item ($snCatId): $($response.StatusCode) $($response.StatusDescription)") return $false } return $true }     I scheduled this task to run every 60 minutes. We don't do any transformation on the ServiceNow 'meta' column as it appears to work fine with comma delimited list of keywords. ... View more
