My Question or Issue

Hi, I'm using the Spotify Web API and Spotify Web Playback SDK to create an app where I can basically sort my playlists .

1. I use the "GET /v1/me/playlists" query to get all the user's playlists (with "fields" and "limit" parameters).
2. I use the "GET /v1/playlists/{playlist_id}/tracks" query to get all the tracks from all the playlists (with the "fields", "limit" and "market" parameters to know if a track can be played through the Web Playback SDK with the is_playable property).
3. I use the "DELETE /v1/playlists/{playlist_id}/tracks" command to remove the selected tracks from the playlist (I give the URIs I retrieved from the previous query).

When using the 3rd command, I receive an HTTP 200 response saying everything went fine but when I go to the Spotify App, the tracks are still there. When I remove the "market" parameter from the 2nd request, it works because the URIs have changed and are correct but I lose the "is_playable" property from the tracks so I can't know if a track can be played through the Web Playback SDK...

Is there a way to have both the "is_playable" information and have the ability to remove tracks ?

Thanks in advance.

I understood my own mistake by simply reading the doc : https://developer.spotify.com/documentation/general/guides/track-relinking-guide/ ...

"IMPORTANT: If you plan to do further operations on tracks (for example, removing the track from a playlist or saving it to “Your Music”), it is important that you operate on the **original** track id found in the `linked_from` object. Using the ID of the linked track returned at the root level will likely return an error or other unexpected result."

So what I did is use the relinked URI instead of the URI from the track and now it works ! Thanks anyway !
