Google Calender API - Get eventID In a Calender - google-calendar-api

Question

I need to get eventID's of a Calendar. I list events and some information about them but i can not get their ID's. I used this doc: https://developers.google.com/calendar/api/v3/reference/events/list
// Print the next 10 events on the user's calendar.
$calendarId = 'xxxx#group.calendar.google.com';
$optParams = array(
'maxResults' => 100,
'orderBy' => 'startTime',
'singleEvents' => true,
'timeMin' => date('c', strtotime("monday -1 week")),
'timeMax' => date('c'),
);
$results = $service->events->listEvents($calendarId, $optParams);
$events = $results->getItems();
if (empty($events)) {
print "No upcoming events found.\n";
} else {
//print "Upcoming events:\n";
foreach ($events as $event) {
$start = $event->start->dateTime;
if (empty($start)) {
$start = $event->start->date;
}
printf("%s %s\n", $event->getSummary(), $start);
}
}
}

Answer 1

The method events.list
Returns a response
{
"kind": "calendar#events",
"etag": etag,
"summary": string,
"description": string,
"updated": datetime,
"timeZone": string,
"accessRole": string,
"defaultReminders": [
{
"method": string,
"minutes": integer
}
],
"nextPageToken": string,
"nextSyncToken": string,
"items": [
events Resource
]
}
Which contains a list of Event Resources
An event resource has a field called id.
{
"kind": "calendar#event",
"etag": etag,
"id": string,
....
So depending upon which language you would be using it would just be a matter of looping though each of the items returned by the method and then accessing the id of that event.
C# example.
foreach(var event in response.Items){
Console.WriteLine(event.Id)
}
