<# .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 Finance & Operations .PARAMETER EntityName Name of the Data Entity you want to work against The parameter is Case Sensitive, because the OData endpoint in D365FO is Case Sensitive Remember that most Data Entities in a D365FO environment is named by its singular name, but most be retrieve using the plural name E.g. The version 3 of the customers Data Entity is named CustomerV3, but can only be retrieving using CustomersV3 Look at the Get-D365ODataPublicEntity cmdlet to help you obtain the correct name .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 CrossCompany Instruct the cmdlet / function to ensure the request against the OData endpoint will search across all companies .PARAMETER RetryTimeout The retry timeout, before the cmdlet should quit retrying based on the 429 status code Needs to be provided in the timspan notation: "hh:mm:ss" hh is the number of hours, numerical notation only mm is the number of minutes ss is the numbers of seconds Each section of the timeout has to valid, e.g. hh can maximum be 23 mm can maximum be 59 ss can maximum be 59 Not setting this parameter will result in the cmdlet to try for ever to handle the 429 push back from the endpoint .PARAMETER ThrottleSeed Instruct the cmdlet to invoke a thread sleep between 1 and ThrottleSeed value This is to help to mitigate the 429 retry throttling on the OData / Custom Service endpoints It makes most sense if you are running things a outer loop, where you will hit the OData / Custom Service endpoints with a burst of calls in a short time .PARAMETER Tenant Azure Active Directory (AAD) tenant id (Guid) that the D365FO environment is connected to, that you want to access through OData .PARAMETER Url URL / URI for the D365FO environment you want to access through OData If you are working against a D365FO instance, it will be the URL / URI for the instance itself If you are working against a D365 Talent / HR instance, this will have to be "http://hr.talent.dynamics.com" .PARAMETER SystemUrl URL / URI for the D365FO instance where the OData endpoint is available If you are working against a D365FO instance, it will be the URL / URI for the instance itself, which is the same as the Url parameter value If you are working against a D365 Talent / HR instance, this will to be full instance URL / URI like "https://aos-rts-sf-b1b468164ee-prod-northeurope.hr.talent.dynamics.com/namespaces/0ab49d18-6325-4597-97b3-c7f2321aa80c" .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 Token Pass a bearer token string that you want to use for while working against the endpoint This can improve performance if you are iterating over a large collection/array .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 D365FO environment. It will use the default OData configuration details that are stored in the configuration store. .EXAMPLE PS C:\> $token = Get-D365ODataToken PS C:\> Get-D365ODataEntityDataByKey -EntityName CustomersV3 -Key "dataAreaId='DAT',CustomerAccount='123456789'" -Token $token This will get the specific Customer from the OData endpoint. It will get a fresh token, saved it into the token variable and pass it to the cmdlet. 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'" -RetryTimeout "00:01:00" This will get the specific Customer from the OData endpoint, and try for 1 minute to handle 429. 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 only try to handle 429 retries for 1 minute, before failing. 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'" -ThrottleSeed 2 This will get the specific Customer from the OData endpoint, and sleep/pause between 1 and 2 seconds. 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 ThrottleSeed 2 to sleep/pause the execution, to mitigate the 429 pushback from the endpoint. 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, [string] $ODataQuery, [switch] $CrossCompany, [Timespan] $RetryTimeout = "00:00:00", [int] $ThrottleSeed, [Alias('$AadGuid')] [string] $Tenant = $Script:ODataTenant, [Alias('Uri')] [string] $Url = $Script:ODataUrl, [string] $SystemUrl = $Script:ODataSystemUrl, [string] $ClientId = $Script:ODataClientId, [string] $ClientSecret = $Script:ODataClientSecret, [string] $Token, [switch] $EnableException, [switch] $OutputAsJson ) begin { if ([System.String]::IsNullOrEmpty($SystemUrl)) { Write-PSFMessage -Level Verbose -Message "The SystemUrl parameter was empty, using the Url parameter as the OData endpoint base address." -Target $SystemUrl $SystemUrl = $Url } if ([System.String]::IsNullOrEmpty($Url) -or [System.String]::IsNullOrEmpty($SystemUrl)) { $messageString = "It seems that you didn't supply a valid value for the Url parameter.
