Variable substitution in rest api filter parameters

Joshua King  Thank you so much for the reply.

I am looking to perform the inject step prior to the import-csv. So that the script can become more generic and others can just change the $param and $filter from the top portion of variable assignments rather than allowing them to edit inside the script.

$param = 'vf_Filter1={0}&vf_Filter2={1}'

 $Filter = $param -f $_.'Fit Name', $_.'Set Name'

Import-Csv $filterfile | ForEach-object{

$Uri = "$server/api/3.5/sites/$siteID/views/$responseD/PDF?$Filter"
    Invoke-RestMethod -Uri $Uri
}
