Hi @<1747066118549278720:profile|WhoppingToad71> , can you share the use case? You want to upload the file to some storage? Or upload to a task?

I want to upload an image that will be used from a task, so I was thinking uploading it to a task and then retrieving it as an artifact from other tasks would work, unless there's a better way

Can I suggest using the sdk? It will do both, log it to the task and will upload it to any storage wanted, like in this example

Thanks, I know it can be done with the SDK. I was hoping there was also a way to upload through the REST API as I'm trying to do it from a non-python app.

With the API you can register an artifact to a task, but the upload will be done separately with the ClearML sdk (the sdk wrap the registration and upload, with some other things inside the upload_artifact function).
