Powershell parallel execution of different commands inside script

Question

I have a PS1 file with Invoke-RestMethod on 10 different urls. I want to make them execute in parallel and get the data from them. All the examples I've seen are for running scripts in parallel.

How can I execute:

$dataA = Invoke-RestMethod -Uri 'https://xyz/A' -WebSession $WebSession -Method Post -Body $queryA
.
.
.
$dataK = Invoke-RestMethod -Uri 'https://xyz/K' -WebSession $WebSession -Method Post -Body $queryK

The above code in parallel, such that I could use the data in dataA to dataK outside the parallel block.

Thanks

You can use Powershell Workflow.

workflow paralleltest {
    
     parallel {
    
       $dataA = Invoke-RestMethod -Uri 'https://xyz/A' -WebSession $WebSession -Method Post -Body $queryA

       $dataK = Invoke-RestMethod -Uri 'https://xyz/K' -WebSession $WebSession -Method Post -Body $queryK
    
      }
    }

You could use the cmdlet "ForEach-Object" with the parameter "-Parallel" explained here: PowerShell ForEach-Object Parallel Feature

Although, I havent done it before, I would suggest the following:

Define your variables $dataA..$dataZ

2.$dataA..$dataZ|ForEach-Object...-parallel
