Google Calendar API v3 Returns "Not Found" on event update

Ok first, if this question has been answered, just point me in the right direction. I have searched and searched without being able to find the answer to what I am running into.

Here's the scenario, I have an application that should be able to do the following:

• Get the list of events for the specified calendar
• Determine start and end times for events
• If the start time is wrong (i.e. we created events at 6:01 am instead of 6:00 am), it needs to adjust the start time
• Submit a POST request to update the start and end times.

So far I have run 1-3 without issue, my problem is number 4. I have a list of events, I changed the time and created a post request, however it always comes back with "Not Found" and I am completely confused.

Here is part of the response that I get back when I request a list of events:

[1] => stdClass Object

            )

            (

                [timeZone] => America/New_York
            )

        [recurrence] => Array
            (
                [0] => RRULE:FREQ=WEEKLY;UNTIL=20130331T000000Z
            )

        [iCalUID] => ###############################
        [sequence] => 0
        [attendees] => Array
            (
                [0] => stdClass Object
                    (
                        [email] => ####################
                        [displayName] => ##############
                        [responseStatus] => needsAction
                    )

            )

        [reminders] => stdClass Object
            (
                [useDefault] => 1
            )

    )

      

        
        
        
      

    

as you can see I get the event id with no problem, then wrap around and create a post request using the calendar id and the event id I just got

https://www.googleapis.com/calendar/v3/calendars/{CALENDAR ID}/events/dbqcfrdvkm40tnuvbk46mv1ktg?key={API KEY}

      

        
        
        
      

    

and this is where I am stuck, the only response I get is "Not Found" even though the headers sent with the request look fine

Array
(
[url] => https://www.googleapis.com/calendar/v3/calendars/{CALENDAR ID}/events/dbqcfrdvkm40tnuvbk46mv1ktg?key={API KEY}

[certinfo] => Array
    (
    )

[redirect_url] => 
[request_header] => POST /calendar/v3/calendars/{CALENDAR ID}/events/dbqcfrdvkm40tnuvbk46mv1ktg?key={API KEY} HTTP/1.1
Host: www.googleapis.com
Accept: */*
Content-Type: application/json
Authorization: Bearer {SECURITY TOKEN}, X-JavascriptUser-Agent: HiddenOnes
Content-Length: 105
)

      

        
        
        
      

    

If I went to the Google Dev Center and used the Events: update test area, this is the url that generated:

https://www.googleapis.com/calendar/v3/calendars/{CALENDAR ID}/events/dbqcfrdvkm40tnuvbk46mv1ktg?key={YOUR_API_KEY}

      

        
        
        
      

    

And if I test it from there, it works great, so I'm completely stumped right now, so any helpful, helpful ideas would be welcome.
