fix(spotify): use an extended-quota client ID for the Web API - #368
fix(spotify): use an extended-quota client ID for the Web API#368abguymon wants to merge 2 commits into
Conversation
cliamp authenticated Web API calls with the librespot keymaster client_id,
which is the playback identity shared by every librespot-based player. Spotify
applies quota per client_id globally, so that pool runs hot and users see
sustained 429 Too Many Requests on search and playlist loading.
Split the two identities, matching what ncspot and spotify-player already do:
- PlaybackClientID (keymaster) keeps minting the streaming grant.
- DefaultClientID is now ncspot's client_id, registered in Extended Quota
Mode, and is used for the Web API when the user has not set their own.
Extended Quota Mode is exempt from both the Nov 2024 and Feb 2026 Development
Mode restrictions, so playlists the user follows but does not own now load
instead of failing with 403 Forbidden (bjarneo#214). Since dd04d28 removed the
ownership filter those playlists are listed in the library, so the failure was
reachable from the UI with no explanation attached.
The docs and setup wizard recommended registering a personal app, which today
places the user in Development Mode and reintroduces the 403. Both now
recommend the built-in identity and spell out the restrictions.
Existing users are prompted to sign in once more: the stored refresh token was
issued to keymaster, and the existing invalid_grant path clears it.

Address CodeRabbit review on bjarneo#368. oauthScopes includes "streaming", and every Web API flow requested the full set. Since August 2026 login5 rejects playback credentials minted by anything but keymaster, so for a separate Web API client that grant is unusable and the consent screen asks the user to approve streaming for a client that cannot stream. webAPIScopes now drops it for non-keymaster clients and keeps the full set for keymaster, which authorizes playback in the same flow. This already applied to custom client IDs before this branch; routing the default through the same path made it everyone's consent screen. Also correct two documentation inconsistencies: - docs/spotify.md still said the built-in path completes in one authorization step, which stopped being true when the default gained a separate playback flow. - config.toml.example described the Development Mode playlist restriction as having no workaround but the built-in client_id. Any app in Extended Quota Mode is exempt. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Field notes from a machine running Omarchy's packaged cliamp v1.63.2 with a personal Development Mode What we hit
That paging path is already on How this PR (#368) differs — and why it is still useful This change is not the same as paging. It splits:
That matches what we saw: keymaster as a Web API client is a global 429 pool. Paging does not fix that. For users who follow the old docs and omit What it does not replace
Review nits
Suggestion: land #368 for the default/no- Happy to re-test a build of this branch against the same account if useful. |

Problem
cliamp uses the librespot keymaster
client_id(65b70807…) for both playback and the Web API.docs/spotify.mddescribes this as the identity "librespot and spotify-player use" — that's true for playback, but not for the Web API, and the difference matters:client_idglobally. Keymaster is shared by every librespot-based player in existence, so its Web API pool is permanently hot and429 Too Many Requestson search and playlist loading is routine rather than occasional.403 Forbidden.Since dd04d28 removed the
playlistAccessible()ownership filter, followed playlists are listed in the library — so the 403 is now reachable straight from the UI. That commit also removed the branch that turned it into a readable message, so it surfaces as a barespotify: list tracks: http status 403 Forbidden.This is the underlying issue in #214.
What other clients do
ncspot keeps two distinct identities, and spotify-player defaults to the same pair:
65b70807…ncspot/src/spotify.rs:152d420a117…ncspot/src/spotify_api.rs:49ncspot's
client_idis registered in Extended Quota Mode. It predates the November 2024 changes and is explicitly exempt from the February 2026 ones — "Apps in extended quota mode are not affected by any of the changes described in this guide." spotify-player's README recommends against overriding it: "You almost certainly should not configure your ownclient_id."Changes
PlaybackClientID(keymaster, still mints thestreaminggrant) andDefaultClientID(ncspot's, used for the Web API when the user hasn't set their own).interactiveOAuthFlowsnow keys the single-flow path offPlaybackClientID. The default path becomes two flows in one browser tab — web api, then playback — which is what a customclient_idalready did.isExtendedQuotaClientreplaces the directDefaultClientIDcomparison guarding the one-request search path, so both built-in identities keep it.config.toml.example, and the setup wizard recommended registering a personal app. They now recommend the built-in identity and state the Development Mode restrictions plainly; the wizard's picker defaults to it.Migration
Existing users sign in once more. The stored refresh token was issued to keymaster and won't refresh against the new Web API client; the existing
