How to retrieve original file with Lightroom API

[Thikkes]

Using the Lightroom API, I can successfully retrieve a rendition of an image (jpg) from a authorised user. 

How can I proceed and retrieve the original file (e.g., .dng, .arw, ...)?

i have same question

Lightroom doesn’t currently offer an API to download originals.

We can consider this as a future enhancement request.  Would be good to understand your workflow needs further in order to help us prioritize it.

Thanks,

It's need for organize backup by API to HDD storage or other cloud storage with all files (original, xmp and renditions).

Landing page https://developer.adobe.com/lightroom said "Adjust your full-resolution shots and have both your originals and edits backed up to the cloud."

But when I try to access to asset to "/master" link I get 403 error. Without originals (jpg or raw) you can’t say that I can make a backup.

Unfortunately, the Adobe Lightroom download utility does this 1) with inconveniently catalog 2) not automatically
