How to Upload Files to UploadThing in N8N

No official n8n node for UploadThing exists. I spent an hour looking for workarounds before figuring out the actual solution.

Here's what works instead:

The Setup

You need two things:

1. A Code node that generates a presigned URL
2. An HTTP Request node that uploads your file to that URL

Step by Step

1. Get your API key from UploadThing platform settings.

2. Add a Code node with the JavaScript below.

This generates the presigned URL for the actual upload.

3. Add an HTTP Request node

Point it to the URL generated by the Code node.

That's it. No custom integrations, no community nodes to maintain, no waiting for official support.

The presigned URL approach works because UploadThing uses standard S3-compatible uploads under the hood.
