403 Forbidden message when calling the v3 Google Calendar API using a Service Account via OAuth 2.0

This is a follow on from my thread about a 401 error when using the Google Calendar API and OAuth2, which can be found here

This contains details of the account setup that leads onto my next question, so I wont repeat myself in this thread.

OK, so when when I call the following code to update a Calendar event I get a 403 forbidden error.

for (Event event : events.getItems())
{
    event.setSummary("XXX" + event.getSummary());

    Event updatedEvent = calendar.events().update(CALENDAR_ID, event.getId(), event).execute();
}

Here is the returned error message:

com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
    "code" : 403,
    "errors" : [ {
        "message" : "Forbidden"
     } ],
    "message" : "Forbidden"
}

What have I tried? Well, I have re-read the (rather poor) Google documentation about Service Accounts, re-checked my API Console account settings, tried changing the code that builds the credential (this leads to other errors so is a regression on my previous thread).

In short, nothing works, so is there anything obvious I am missing?

For me, after trying all of the suggested solutions above, nothing worked. I got it to work after looking what scopes they were using in the documentation.

I was fetching for events, and it seemed that the https://www.googleapis.com/auth/calendar scope wasn't enough. I had to add https://www.googleapis.com/auth/calendar.events as well to my scopes.

Hopefully it can help someone out there!

In my case I had to enable the CalDAV API in the Google API console. It gives a 403 response if disabled.

I know this is an old question, but this might be helpful for someone.

I was also getting the same error even after sharing the calendar as in the Justin's answer. After comparing with another working sample figured out that I have set

var SCOPES = ["https://www.googleapis.com/auth/calendar.readonly"];

instead of 

var SCOPES = ["https://www.googleapis.com/auth/calendar"];

Hope this helps anyone who has done a similar mistake and getting this error.

Solved, thanks to this post.

You have to share the calendar from your Google Calendar account with the Service Account email that is generated in the Google API Console, e.g. [email protected].

I can now update my calendar from my web service.
