Updates

Building AddEvent with our users is the real deal to us.
We keep track with all changes made so our users are kept in the loop.

Update (Tuesday, July 19, 2016)

Added

When you are using the "Add to Calendar" button on a website you should white list the domain in the "Domains" section. We frequently get asked by users, who use AddEvent for multiple websites, if we can make this process automatic.

We have added a new tag ("client") in the "Add to Calendar" button code which is an account identifier. When added, domains are automatically created in the accounts list of domains.

We have also made some changes in the "Domains" section. Before you had to add sub domains and the root domain. Now you only have to add the root domain. We have added domain control in the section as well, which allows you to delete / disable a domain, e.g. if someone exploits your client id or if you don't use the domain anymore.

Update (Wednesday, July 13, 2016)

Information

Our service has been down for a number of our users. We are terribly sorry about that! Our service was hit / requested a lot of times from one or more services, very alike a (DoS) attack. That ate up all of our database connections. The connection has been flushed and everything is up and running again.

Update (Wednesday, June 22, 2016)

Added

We have added two new variable types to the "Add to Calendar" button as well as the "Direct URL Method" (API). The two new variable types have been requested by users who have very specific advanced needs. For normal usage we don't recommend changing the variables.

New variables:

STATUS: Define the status parameter in the .ics file used for e.g. Outlook and Apple Calendar. The options can be "CONFIRMED", "TENTATIVE", "CANCELLED", "NEEDS-ACTION", "COMPLETED", "IN-PROCESS". If the value is not defined our system will default to "CONFIRMED".

UID: Define your own UID for the event. If there isn't specified any UID our system will generate a standard UID.
