Answer 1

To store api keys you can use Application Settings. Details: https://docs.microsoft.com/en-us/azure/azure-functions/functions-how-to-use-azure-function-app-settings#application-settings

To get an environment variable or an app setting value, use System.Environment.GetEnvironmentVariable, as shown in the following code example:

public static void Run(TimerInfo myTimer, TraceWriter log)
{
    log.Info($"C# Timer trigger function executed at: {DateTime.Now}");
    log.Info(GetEnvironmentVariable("AzureWebJobsStorage"));
    log.Info(GetEnvironmentVariable("WEBSITE_SITE_NAME"));
}

public static string GetEnvironmentVariable(string name)
{
    return name + ": " + 
        System.Environment.GetEnvironmentVariable(name, EnvironmentVariableTarget.Process);
}
