Relation between WorkSpace, DataFlow , Dataset and Report of Power BI

Hi avatorl 

Now i have got data using Admin account but still have some query.

DataFlow->DataSet : To fetch detail, Invoke-PowerBIRestMethod will be used and need to pass workspaceid to it, can understand, if i want to retreive detail of all the dataflow, i need to pass workspaceid one by one, is there any way of writing script whic take all the workspaceid one by one and consolidate detail of all the dataflow into CSV. 

$url="https://api.powerbi.com/v1.0/myorg/admin/groups/{groupId}/datasets/upstreamDataflows"
$result = Invoke-PowerBIRestMethod -Url $url -Method Get

For e.g, if i have 10 workspace in organization, i need to pass workspaceid (groupid) again and again and its manual too, Is there any way of writing Powershell script via which i can pass all 10 workspaceid one by one at once programatically. 

Workspace -> Dataflow (the way you suggested)  : Again, how to write script which can iterate based on workspaceid.

Thanks

Amit

$Workspaces = Get-PowerBIWorkspace
foreach ($workspace in $Workspaces) {
Write-Host $workspace.id Write-Host $workspace.name
}

Hi avatorl  Thanks for all your inputs !!!

Any help here would be really appreciable.

1. Relation ship between Workspace and Dataflow 

Script Used : 
$Workspaces = Get-PowerBIWorkspace
$res = @( foreach ($workspace in $Workspaces) {Get-PowerBIDataFlow -Workspace $workspace }) | Export-Csv -NoTypeInformation -Path C:\Azure\Dataflow.csv

Result : Its giving me detail of Dataflow only such Dataflow Id, Dataflow Name etc.

-  Will it be possible to include the workspace ID which i have passed above in script in the Output.

2. WorkSpace - Dataset 

Script Used : Get-PowerBIDataset

Output - No relationship between Workspace ,dataflow and reports are there.

3. WorkSpace - Report 

 Script Used : Get-PowerBIReport

This gives relation ship with Dataset, any way to have relation between workspace, dataflow as well.

4. Any scipt that says relation ship between Report to Workspace, Dataflows , dataset , users etc will be great help!!

THanks
