<# .SYNOPSIS Get data from an Data Entity using OData, providing a key .DESCRIPTION Get data from an Data Entity, by providing a key, using the OData endpoint of the Dynamics 365 Customer Engagement .PARAMETER EntityName Name of the Data Entity you want to work against The parameter is Case Sensitive, because the OData endpoint in D365CE is Case Sensitive Remember that most Data Entities in a D365CE environment is named by its singular name, but most be retrieve using the plural name E.g. The builtin account Data Entity is named Account, but can only be retrieving using accounts .PARAMETER Key A string value that contains all needed fields and value to be a valid OData key The key needs to be a valid http encoded value and each datatype needs to handled appropriately .PARAMETER ODataQuery Valid OData query string that you want to pass onto the D365 OData endpoint while retrieving data OData specific query options are: $filter $expand $select $orderby $top $skip Each option has different characteristics, which is well documented at: http://docs.oasis-open.org/odata/odata/v4.0/odata-v4.0-part2-url-conventions.html .PARAMETER Tenant Azure Active Directory (AAD) tenant id (Guid) that the D365CE environment is connected to, that you want to access through OData .PARAMETER Url URL / URI for the D365CE environment you want to access through OData .PARAMETER ClientId The ClientId obtained from the Azure Portal when you created a Registered Application .PARAMETER ClientSecret The ClientSecret obtained from the Azure Portal when you created a Registered Application .PARAMETER EnableException This parameters disables user-friendly warnings and enables the throwing of exceptions This is less user friendly, but allows catching exceptions in calling scripts .PARAMETER OutputAsJson Instructs the cmdlet to convert the output to a Json string .EXAMPLE PS C:\> Get-D365ODataEntityDataByKey -EntityName CustomersV3 -Key "dataAreaId='DAT',CustomerAccount='123456789'" This will get the specific Customer from the OData endpoint. It will use the "CustomerV3" entity, and its EntitySetName / CollectionName "CustomersV3". It will use the "dataAreaId='DAT',CustomerAccount='123456789'" as key to identify the unique Customer record. It will NOT look across companies. It will use the default OData configuration details that are stored in the configuration store. .EXAMPLE PS C:\> Get-D365ODataEntityDataByKey -EntityName CustomersV3 -Key "dataAreaId='DAT',CustomerAccount='123456789'" This will get the specific Customer from the OData endpoint. It will use the "CustomerV3" entity, and its EntitySetName / CollectionName "CustomersV3". It will use the "dataAreaId='DAT',CustomerAccount='123456789'" as key to identify the unique Customer record. It will make sure to search across all legal entities / companies inside the D365CE environment. It will use the default OData configuration details that are stored in the configuration store. .LINK Add-D365ODataConfig .LINK Get-D365ActiveODataConfig .LINK Set-D365ActiveODataConfig .NOTES The OData standard is using the $ (dollar sign) for many functions and features, which in PowerShell is normally used for variables. Whenever you want to use the different query options, you need to take the $ sign and single quotes into consideration. Example of an execution where I want the top 1 result only, from a specific legal entity / company. This example is using single quotes, to help PowerShell not trying to convert the $ into a variable. Because the OData standard is using single quotes as text qualifiers, we need to escape them with multiple single quotes. -ODataQuery '$top=1&$filter=dataAreaId eq ''Comp1''' Tags: OData, Data, Entity, Query Author: Mötz Jensen (@Splaxi) #> function Get-D365ODataEntityDataByKey { [CmdletBinding(DefaultParameterSetName = "Default")] [OutputType()] param ( [Parameter(Mandatory = $true, ParameterSetName = "Specific")] [Alias('Name')] [string] $EntityName, [Parameter(Mandatory = $true, ParameterSetName = "Specific")] [string] $Key, [Parameter(Mandatory = $false)] [string] $ODataQuery, [Parameter(Mandatory = $false)] [Alias('$AADGuid')] [string] $Tenant = $Script:ODataTenant, [Parameter(Mandatory = $false)] [Alias('URI')] [string] $URL = $Script:ODataUrl, [Parameter(Mandatory = $false)] [string] $ClientId = $Script:ODataClientId, [Parameter(Mandatory = $false)] [string] $ClientSecret = $Script:ODataClientSecret, [switch] $EnableException, [switch] $OutputAsJson ) begin { $bearerParms = @{ Url = $Url ClientId = $ClientId ClientSecret = $ClientSecret Tenant = $Tenant } $bearer = New-BearerToken @bearerParms $headerParms = @{ URL = $URL BearerToken = $bearer } $headers = New-AuthorizationHeaderBearerToken @headerParms $apiPath = Get-PSFConfigValue -FullName "d365ce.integrations.api.version" } process { Invoke-TimeSignal -Start Write-PSFMessage -Level Verbose -Message "Building request for the OData endpoint for entity: $entity." -Target $entity [System.UriBuilder] $odataEndpoint = $URL $odataEndpoint.Path = "$apiPath/$EntityName($Key)" if (-not ([string]::IsNullOrEmpty($ODataQuery))) { $odataEndpoint.Query = "$ODataQuery" } try { Write-PSFMessage -Level Verbose -Message "Executing http request against the OData endpoint." -Target $($odataEndpoint.Uri.AbsoluteUri) $res = Invoke-RestMethod -Method Get -Uri $odataEndpoint.Uri.AbsoluteUri -Headers $headers -ContentType 'application/json' if ($OutputAsJson) { $res | ConvertTo-Json } else { $res } } catch [System.Net.WebException] { $webException = $_.Exception if(($webException.Status -eq [System.Net.WebExceptionStatus]::ProtocolError) -and (-not($null -eq $webException.Response))) { $resp = [System.Net.HttpWebResponse]$webException.Response if($resp.StatusCode -eq [System.Net.HttpStatusCode]::NotFound){ $messageString = "It seems that the OData endpoint was unable to locate the desired entity: $EntityName, based on the key: <c='em'>$key</c>.
