RESTED身份验证失败，API凭证丢失或无效

Question

我试图在我的应用程序中使用Calendarific api，但是我从RESTED中获得了丢失或无效的api凭据

{
    "meta": {
        "code": 401,
        "error_type": "auth failed",
        "error_detail": "Missing or invalid api credentials. See https://calendarific.com/api for details."
    },
    "response": []
}
