How do I upload to Code Buckets from Windows PowerShell?

For files up to 4 MiB:

$h = @{ Authorization = "Bearer $env:CLATTER_API_KEY"; "X-Clatter-Account" = $env:CLATTER_ACCOUNT_ID }
Invoke-RestMethod -Method Post -Headers $h -ContentType "image/png" `
  -Uri "https://api.codebuckets.clatterlabs.xyz/v1/buckets/BUCKET_ID/objects?name=logo.png" `
  -InFile .\logo.png

For bigger files, run the Python or Node.js uploader from the Uploads guide; both work on Windows.
