Calendar Sync

Nerevu Group uses Fastmail Calendar to keep everyone up to date on events that are happening. This section will show you how to sync your existing calendars so that they update Fastmail. In general, there are two options for syncing with your teammates:

  1. Show them your events with the titles and all details (this is good for a “Work” calendar)

  2. Or show them an event block that just indicates that you are busy during that block (no details are shared - this is good for time blocks when you are busy but don’t need to share details about why)

We will go over how to setup both of these syncs.

From Google Calendars

Ngrok is a service that allows you to forward localhost to the public web through https. This comes in handy when you’re testing code that interacts with an API that requires a valid https URL (like QuickBooks in the Comissioner API).

You can see how to use it by looking at the commissioner-api README.

Visit Ngrok’s website to learn more about it.
