Hi,
The latest GMS 8.5.1 has built-in load balancing for chat servers, so WebAPI server is no longer required. GMS has its own internal interface to chat servers. WebAPI was previously used for load balancing purposes only.
GMS offers REST API, Cometd support, push notifications, iOS and Android sample code, which are some of the advantages over built your own or WebAPI.
Hope this helps.

Hi guys
First off, I am a certified Genesys engineer and have certainly RTFM'd, and been working with the products for >10 years..
I am very familiar with the old ICS, and eServices. So I'm hopefully not asking any stupid questions here

**But** I am still getting my head around the Mobile Services, and quite frankly am struggling to understand how it fits in with the other components.
ORS asside, I'm just referering to the WebAPI server, MobileServices, WebCallBack server etc.
Hopefully you can can help to clarify a few questions I have:
- I presume it is possible to integrate to a smartphone app using the WebAPI Server - I have used this for chat before with eServices. I guess it just won't be as feature rich??
- In your opinion is the Mobile Services 'worth it'? any thoughts on it's use?
- The Web API Server - this is still a required component with the Mobile Services for chat? (and/or web callback)
Thanks in advance
DJM
