V2: get_activities API Not Working

Looks like V2 API for get_activities call is not returning any data since 8/27/2018 10.30 AM. Are there any know issues around it?

Our API v2 has been deprecated since October 1, 2017. While it is still up and running for the time being, we are not maintaining it and endpoints will continue to stop functioning as we update things in CATS. We recommend that you migrate to API v3.

Got it Thanks! We will get onto the migrating to use new APIs. Are there any C# samples for consuming the APIs?

Unfortunately, we do not have any code samples in any languages. Our docs do describe all the endpoints though, so you should be able to use any generic REST requests library to access them.
