Integration with other apps

Fantastical supports the following URL actions:

fantastical2://parse?sentence=[input] — Begin creating a new event with the given sentence. The notes parameter can also be added to specify a note with the event. For example: fantastical2://parse?sentence=sentence&notes=[your note]. The following parameters are also supported: add (set to 1 to automatically add an event - be careful!), reminder, due (requires the format yyyy-MM-dd HH:mm), title, location, url, notes, private (Exchange only), start, end, allDay (start/end require the format yyyy-MM-dd HH:mm, allDay can be 1 or 0). If you use the sentence parameter it will cause other parameters to be ignored.

fantastical2://show?date=yyyy-mm-dd — Jumps to the specified date. You can also use a natural language date such as "Tuesday" or "next month" and Fantastical will do its best to show the date.

Fantastical supports x-callback-url. x-callback-url can be used by using fantastical2://x-callback-url/parse?parameters or fantastical2://x-callback-url/show?parameters. The parameters x-source, x-success, x-cancel, and x-error are all supported. Refer to the x-callback-url site for more details.

Fantastical is also officially supported by Launch Center Pro.
