Error 403 on using the Translate API

[patrick...@autodesk.com]

I have just setup fully (billing included) a new account and project to use the Translate API but I still get the 403 error:

{
 "error": {
  "errors": [
   {
    "domain": "usageLimits",
    "reason": "accessNotConfigured",
    "message": "Access Not Configured. Please use Google Developers Console to activate the API for your project."
   }
  ],
  "code": 403,
  "message": "Access Not Configured. Please use Google Developers Console to activate the API for your project."
 }
}

Thanks for quick help on this
