api.spotify.com CORS preflight broken

thuvarT — Wed, 22 Jul 2026 15:47:35 GMT

Browser apps calling the Spotify Web API are failing with CORS errors on authenticated requests (e.g. GET https://api.spotify.com/v1/me).

The OAuth login popup can still open/complete, but the follow-up browser fetch to api.spotify.com fails because the CORS preflight is broken.

Reproduction:

1) Broken — browser-style preflight WITH Origin
curl -i -X OPTIONS "https://api.spotify.com/v1/me" \
-H "Origin: https://example.com" \
-H "Access-Control-Request-Method: GET" \
-H "Access-Control-Request-Headers: authorization"

Actual response:
HTTP/1.1 200 OK
Content-Length: 0
(no Access-Control-Allow-Origin / Allow-Methods / Allow-Headers)

This also fails the same way with:
- Origin: https://dashboard-staging.lyricfind.com
- Origin: http://localhost:3000

So it does not appear to be app/domain specific.

2) Control — OPTIONS WITHOUT Origin
curl -i -X OPTIONS "https://api.spotify.com/v1/me" \
-H "Access-Control-Request-Method: GET" \
-H "Access-Control-Request-Headers: authorization"

Response:
HTTP/1.1 204 No Content
allow: GET, HEAD, OPTIONS

3) Control — accounts.spotify.com token OPTIONS still works
curl -i -X OPTIONS "https://accounts.spotify.com/api/token" \
-H "Origin: https://example.com" \
-H "Access-Control-Request-Method: POST" \
-H "Access-Control-Request-Headers: content-type"

Response includes:
access-control-allow-origin: https://example.com
access-control-allow-methods: OPTIONS, GET, POST, DELETE, PUT

4) GET responses still include CORS headers, but browsers never reach GET if preflight fails:
access-control-allow-origin: *

Impact
Any browser client calling api.spotify.com with Authorization (which triggers preflight) is blocked. We are seeing this across multiple independent web apps.

Please investigate CORS handling for OPTIONS requests to api.spotify.com when an Origin header is present.
