My Question or Issue

Hi everyone,

I’m seeing an issue with the Spotify Web API when adding items to a playlist.
Here’s what happens:

• I successfully created a playlist using the /v1/users/{user_id}/playlists endpoint.

• I then call POST /v1/playlists/{playlist_id}/tracks to add track URIs (e.g., spotify:track:xxxx).

• The call returns 201 Created with a snapshot_id, indicating success.

• When I subsequently fetch the playlist (GET /v1/playlists/{playlist_id}/tracks), the totalfield shows > 0, but the items array is empty.

• The playlist appears in my Spotify app, but no tracks are visible — even though the total suggests they were added.

Details:

• Scopes requested: playlist-modify-public playlist-modify-private playlist-read-private.

• Token type: authorization code (user token).

• Using the same token, I can create playlists and add other metadata successfully.

• I’ve verified that my URIs are valid and the API returns no errors.

• Fetching with market=from_token sometimes reveals unplayable tracks, suggesting a visibility/market mismatch.

Expected:
Added tracks should appear in the playlist’s items array and be visible in the client.

Actual:
Playlist total increases, but items array is empty and no tracks appear in Spotify UI.

Question:
Has anyone else experienced this recently? Is this a known issue with the Add Items to Playlist endpoint or playlist market filtering?
