Google calendar API move event

Question

Heres the deal,

On googles developer website they have at the bottom of each api function description a tool to try out the api, specifically I am using the calendar api

Answer 1

I was getting a 404 error, and I assumed it was a credentials problem since that's what other people online wrote about.

Currently, when I browse the Google Calendar website for each of my calendars and visit Share This Calendar, I see the email address of my service account listed with credentials to "Make changes to events". That's on both the origin calendar and the destination calendar.

So I couldn't figure out how to set up my credentials differently.

It turned out not to be a problem with credentials at all.

I had been using the "eid" from the URL of the Google Calendar event webpage and assumed it was the Event ID. It's not.

When I use a valid Event ID, the "move" command worked as documented here.
