You can use below code to access kudu apis from powershell -

 //function to Get webapp's publishing credentials    
    function Get-AzWebAppPublishingCredentials($resourceGroupName, $webAppName, $slotName = $null) {
            if ([string]::IsNullOrWhiteSpace($slotName) -or $slotName.ToLower() -eq "production") {
                $resourceType = "Microsoft.Web/sites/config"
                $resourceName = "$webAppName/publishingcredentials"
            }
            else {
                $resourceType = "Microsoft.Web/sites/slots/config"
                $resourceName = "$webAppName/$slotName/publishingcredentials"
            }
            $publishingCredentials = Invoke-AzResourceAction -ResourceGroupName $resourceGroupName -ResourceType $resourceType -ResourceName $resourceName -Action list -ApiVersion 2015-08-01 -Force
            return $publishingCredentials
    }

 //function to get authorization header from publishing credentials
     function Get-KuduApiAuthorisationHeaderValue($resourceGroupName, $webAppName, $slotName = $null) {
            $publishingCredentials = Get-AzWebAppPublishingCredentials $resourceGroupName $webAppName $slotName
            $ret = @{ }
            $ret.header = ("Basic {0}" -f [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $publishingCredentials.Properties.PublishingUserName, $publishingCredentials.Properties.PublishingPassword))))
            $ret.url = $publishingCredentials.Properties.scmUri
            return $ret
        }

 //function to call kudu api e.g. to get a file from webapp
    function Get-FileFromWebApp($resourceGroupName, $webAppName, $slotName = "", $kuduPath) {
        $KuduAuth = Get-KuduApiAuthorisationHeaderValue $resourceGroupName $webAppName $slotName
        $kuduApiAuthorisationToken = $KuduAuth.header
        $kuduApiUrl = $KuduAuth.url + "/api/vfs/$kuduPath"

        Write-Host " Downloading File from WebApp. Source: '$kuduApiUrl'." -ForegroundColor DarkGray
        $tmpPath = "$($env:TEMP)\$([guid]::NewGuid()).json"
        $null = Invoke-RestMethod -Uri $kuduApiUrl `
            -Headers @{"Authorization" = $kuduApiAuthorisationToken; "If-Match" = "*" } `
            -Method GET `
            -ContentType "application/json" `
            -OutFile $tmpPath
        $ret = (Get-Content $tmpPath) | Out-String | ConvertFrom-Json
        Remove-Item $tmpPath -Force
        return $ret
    }
