We have released APIs for AddEvent.com and CalendarX.com.

For CalendarX.com:
We have released APIs for managing calendars and events. The new API's allows developers to add / edit / delete calendars and add / edit / delete events in the calendars.

https://www.calendarx.com/api

The API's have predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors. All API access is over HTTPS. All data is sent and received as JSON.

In order to communicate with the APIs, developers can use cURL. It's as simple as that. The APIs currently solve basic tasks and will be expanded with features eventually.

Let us know if you have special requests, we do not currently comply.

Information

We had a client hold on our domain. Our host simply forgot to renew the domain (it's complicated). We are doing our best to get things fixed. The issue has been resolved - some DNS hiccups may occur.

Update (Wednesday, October 5, 2016)

Information

BIG launch day. We’ve been working hard this year on a new calendar service, CalendarX.com.

CalendarX is a calendar your audience can follow. When a user follows your CalendarX calendar, you can push your important events to their personal calendar. When you make updates, your audience calendar is automatically updated.

CalendarX is an awesome communications tool and can be used for lots of different purposes.

Schools and institutions
Working at a school or institution? Provide students and parents access to class schedules, parent meetings etc.

Sports
Add schedules and big game days to the calendar and let the team and fans follow the calendar.

Companies:
Promote your events internally to your employees or let fans of your company follow your calendar. Great if you do after-hours events to promote your company.

Online shops and retail:
Remind your audience to come back to your store for more. Promote special deals and make special events.
