Twitch.tv: Gather followers for an account

Ella's Followers.ps1

$users = @("stevenwatsonb","missellacronin")
foreach ($user in $users) {
    "Fetching $user..."
    $url = "https://api.twitch.tv/kraken/channels/$user/follows?direction=ASC&limit=100"
    $headers = @{"Client-ID" = "XXXXXXXXXX"}
    $feed = Invoke-RestMethod -Uri $url -Headers $headers
    $total = $feed._total
    "Retrieving $total follower(s) for $user..."
    $rows = @()
    while (($feed.follows).count -ne 0) {
        foreach ($follower in $feed.follows) {
            $rows += $follower
        }
        $feed = Invoke-RestMethod -Uri $feed._links.next -Headers $headers
    }
    $rows | ConvertTo-Json | Out-File "C:\Temp\$user.json"
    "Follower(s) for $user fetched and saved."
}

I changed the retrieval method from Invoke-WebRequest to Invoke-RestMethod as the latter handles converting JSON to PowerShell Objects for you. :-)

UPDATED: The script now loops through a set of IDs (in this sample, mine and Ella Cronin's) and outputs a JSON file for each ID. I've also updated the end-of-pull criteria to evaluate the number of follows in the batch rather than use a counter (more idiot-proof). You can use Excel 2013/2016's Power Query to import and transform the JSON data.

Also, Twitch now requires that a Client-ID be sent with every request. When you have obtained a Client-ID place it in line 5 where shown by "XXXXXXXXXX".
