Async Message/Queue Service tuts

Question

Hello, are there any tutorials on using the MS? I don't just mean the code samples in the dev center. I am curious what use-cases they apply to, some best practices, best scenarios etc. Can I use them, for example, to get a server side variables, let's say the server version (I don't mean the "real" App42 version, but something I'd call a "version" which I would constantly update after some changes in my dashboard for example, like adding scheduled server custom code events)? Or would custom code be better? Side question: assuming I mistyped the api id or app private key, how can I track failures in Initialize() calls? (without parsing debug logs, but as a callback with onSuccess or Exception)

Hi Xian,

For your second question, where API_Key is wrong, you will get "1401 - UNAUTHORIZED - Client is not authorized" whenever you call any App42 API in onException callback.

For your first question, you can store the version in our Storage module in a JSON Document so that you can update it right from AppHQ dashboard or using UpdateAPI. For fetching it from your application you can just call our FindDocument APIs. 

I hope it helps.

Thanks.

Thank you for your answer! For invalid keys, I know additional API calls trigger 1401, but I think an Init callback is ideal :)
Maybe take into consideration, even if with very low priority, if it won't break the design. As for storing JSON documents with server side static vars/data, I didn't think of that. Thank you for the suggestion!
