'Google Calendar API show all events from public calendar
I'm having trouble following tutorials to get a list of all events in a public calendar. I've tried following along this post: Retrieve Google Calendar events using API v3 in javascript, and the official docs, but I always get a 404 error.
This is the code I have (following the linked post). I am using localhost, and I have a public calendar, and I made an API key with no restrictions, and a client ID with http://localhost as authorized JS origin and Authorized redirect URIs
