Question

Are subscription limits per extension or per user?

I have an application where I’d like to register a webhook for every logged in user (by extensionId). The most sensible way to do this is to have a subscription for each extensionId. However, I’m worried by this piece of documentation “Subscriptions are currently limited to 30 subscriptions per user/extension (for particular application).”

Does this mean I can have up to 30 subscriptions per extensionId, and thus my current use case is no problem? Or is it 30 subscriptions per “user” aka per JWT? I notice that the ListSubscription documentation explicitly states “maxItems:30”, which would suggest the limit is not per extension.

If I have 85 call center representatives who are signed in, how do I make sure I receive webhook call backs for all of them?

 

Thanks for your help!

Can you clarify the context. You mentioned “every logged in user” and you also mentioned “aka per JWT”.

  1. How does your customer login the app? Using their RingCentral user name and password (3-legged authorization) or using their pre-generated JWT?
  2. Or, does the app a server app authenticated by a single super admin user (JWT) and create subscription for other users?
  3. What event filters does your app subscribe to?
  4. Where do you get the info about “30 subscriptions per extensionId”?
