I'm trying to make a request from the Clash Royale API ( link )
Returns the following error:
Access to fetch at 'https://api.clashroyale.com/v1/players/%23C8Q2QR08' from origin 'https://deckroyale.now.sh' has been blocked by CORS policy: Request header field auth is not allowed by Access-Control-Allow-Headers in preflight response.
I always return a CORS policy error, until I put "mode": "no-cors", it returns empty with error 403.
Does anyone have a solution? NOTE: I'm using JavaScript fetch
