Binary File Block
When your API needs a raw file — no form wrapping, no multipart boundaries, just pure binary data — this is your block.
The Binary File Block lets you send a single file directly as the request body, exactly the way some APIs expect it for uploads, imports, or processing.
Voiden handles the content-type detection and binary encoding automatically, so you can focus on what you're uploading, not how it's packaged.

The Binary File Block strips away the complexity of file uploads.
Just your file, delivered directly to the API that needs it.
