Cloud API Unauthorized error

Development Tools Cloud IoT

Hi! I'm new to using IoT Cloud and need help. I generated an API Key to connect my Arduino Uno R4 Wi-Fi to Unity. However, when I try to upload the script in Unity, the 404: Unauthorized error appears. Does anyone know how to solve the problem?

This is the script I use:

IEnumerator GetHeartRate()
{
    string url = "https://api2.arduino.cc/iot/v2/things/{thingId}/properties/{propertyId}/"; // Replace with your API endpoint
    UnityWebRequest request = UnityWebRequest.Get(url);

    // Replace "YOUR_ACCESS_TOKEN" with the correct token
    string accessToken = "YOUR_ACCESS_TOKEN";
    Debug.Log("Access Token: " + accessToken);  // Debug to ensure token is correctly set
    
    request.SetRequestHeader("Authorization", "Bearer " + accessToken);
    
    yield return request.SendWebRequest();
    
    if (request.result != UnityWebRequest.Result.Success)
    {
        Debug.LogError("Error: " + request.error);  // Log the error
        Debug.LogError("Response Code: " + request.responseCode);  // Log the HTTP response code
    }
    else
    {
        string jsonResult = request.downloadHandler.text;
        Debug.Log("Heart rate data: " + jsonResult); // Process the data
    }
}

Hi, how are you generating access token? Here is not present in code you have shared.
You need to generate and access token starting from your API keys.
