Rocksky implements the Last.fm Audioscrobbler API (both the modern 2.0 protocol and the legacy submission protocol). Migrating an existing client usually means changing one URL and swapping credentials.

​
Get your credentials

  1. Sign in to rocksky.app.
  2. Go to your API Applications.
  3. Create an application to get an API key and shared secret.
  4. Generate a session key with rocksky login.

​
Modern Last.fm clients (API 2.0)

Replace the base URL:
Last.fmRocksky
https://ws.audioscrobbler.com/2.0https://audioscrobbler.rocksky.app/2.0
Authentication still uses api_key and sk (session key) parameters with MD5-signed requests:
  1. Sort all request parameters by key alphabetically.
  2. Concatenate key + value pairs into one string.
  3. Append your shared secret.
  4. MD5-hash the result; send it as api_sig.

​
Legacy submission protocol

For older clients (e.g. Deadbeef), use the legacy endpoint: 
https://audioscrobbler.rocksky.app
  • Username: your API key
  • Password: your shared secret

​
Metadata normalization

Rocksky normalizes incoming track metadata before storing it. If the track can’t be matched against a known song, the scrobble is skipped rather than stored as an orphan record.

​
