Hello Folks,

We have integrated Classic ASP / ASP.NET / PHP Application calendar with Google Calendar Version V3.

As per the latest update from Google on November 17 2014 about shut down of Google API V2.


“This API is a subject to the Deprecation Policy and was shut down on November 17, 2014. Please use APIv3 instead.”.


Many software company and the company who relies on the Google Sync with their application Calendar get into trouble due to this.

Variance InfoTech accept this challenge by knowing that its complex to integrate Google Calendar version V3 using Oath protocol.

We implemented integration between Classic ASP / ASP.NET Application with the Google calendar by implementing new API Layer which then integrated with Google Calendar API.
