Embedded Download from Iframe not working

The Download from the SoundCloud embedded player is not working anymore. When clicking on the Download-Icon nothing happens, in the Developer-Console the Status Code is "401 Unauthorized".

It is not working for all my tracks, tracks from other accounts and not even the examples on the Soundcloud Website are working.

When I try to query the API I get the same error 401.

Does anyone else has the same problem? Thousand of our clients are affected by this, but the Soundcloud Support has not responded in over a week.

Title: Embedded Download from Iframe not working

Issue found of: June 6th, 2024

Endpoint(s):

• GET /tracks/{id}/download

Scope(s):

• None (application is not using authentication i.e., implicit flow)

Steps to reproduce:

curl --request GET \
  --url 'https://api-widget.soundcloud.com/tracks/12345/download?format=json&client_id=DONT_SHARE_CLIENT_ID&app_version=1718026023'

Expected behaviour:

Track starts to download

Actual behaviour:

401 Unauthorized (consistently)

Start by running the supplied curl request against GET /tracks/{id}/download and confirm the consistent 401 response for embedded and API requests. The issue names no repository files or tests, so trace whether this endpoint is implemented or documented here. Done means the endpoint restores the expected track download behavior instead of returning 401.
