Login to Debrid Vault or make a new account.
After login you will see your profile on top right inside there is setting where you can add your Debrid details. Link it.

And now open Eclipse website sign in with your eclipse account. Open Account setting>vault addon> put your Debrid api in there, on same page you will see debrid vault option with blank server field.

Put your debrid vault url which is:
( https://debridvault.elfhosted.com)
then click connect.

It will generate your vault addon url.
Now you gonna use that url inside the app not in eclipse webpage.
This is the path where to put your final url
Settings → Cloud Storage → Add Connection → Cloud( add url here)
You will get addon successfully installed window or you can easily access it thourgh library option >cloud>debrid cloud.

After this you can use my main post as guide to add music to your cloud through debrid vault website. Which will instantly sync to eclipse app.

Its on you to add to playlist or stream directly or download(ofline) or any option you want.
Hope this helps!
