I need functions related to manage and integrate into my CMS classic ASP, events of Google Calendar.
1. One function to authenticate to Google Calendar by OAuth 2.0
2. One function to populate events from one calendar and between 2 dates
3. One function to delete an event from one calendar and his id
4. One function to insert an event in one calendar
5. One function to modify an event in one calendar
( 3 - 4 - 5 are optional)
Thanks in advance
