401 error for full stack development

Hello Ready Player Me Support,

I am trying to use the v2 API to generate avatars with a freshly generated API key. My key is assigned to my application and has WRITE permissions for Avatars. However, every request returns a 401 Unauthorized error.

  • Endpoint: https://api.readyplayer.me/v2/avatars
  • Method: POST
  • Headers:
    • Authorization: Bearer [my-key]
    • Content-Type: application/json
  • Body: { "gender": "masculine", "bodyType": "average" }
  • Error: {"type":"UnauthorizedError","status":401,"message":"Unauthorized"}

I have regenerated the key, ensured permissions and app assignment, and tested with curl and PowerShell. Please advise on how to resolve this.

Thank you!
