Calendar Events Notification Not Received on Server

Push notification for google calendar not working

You must implement Watch method. To set up a notification channel for messages about changes to a particular resource, send a POST request to the watch method for the resource.

Each notification channel is associated both with a particular user and a particular resource. A watch request will not be successful unless the current user owns or has permission to access this resource.

Request:

https://www.googleapis.com/apiName/apiVersion/resourcePath/watch

Start watching for changes to a collection of events on a given calendar:

POST https://www.googleapis.com/calendar/v3/calendars/example.com/events/watch
Authorization: Bearer auth_token_for_current_user
Content-Type: application/json

{
  "id": "01234567-89ab-cdef-0123456789ab", // Your channel ID.
  "type": "web_hook",
  "address": "https://example.com/notifications", // Your receiving URL.
  ...
  "token": "target=myApp-myCalendarChannelDest", // (Optional) Your channel token.
  "expiration": 1426325213000 // (Optional) Your requested channel expiration time.
  }
}

Response:

{
  "kind": "api#channel",
  "id": "01234567-89ab-cdef-0123456789ab"", // ID you specified for this channel.
  "resourceId": "o3hgv1538sdjfh", // ID of the watched resource.
  "resourceUri": "https://www.googleapis.com/calendar/v3/calendars/example.com/events", // Version-specific ID of the watched resource.
  "token": "target=myApp-myCalendarChannelDest", // Present only if one was provided.
  "expiration": 1426325213000, // Actual expiration time as Unix timestamp (in ms), if applicable.
}

After creating a new notification channel to watch a resource, the Google Calendar API sends a sync message to indicate that notifications are starting. The X-Goog-Resource-State HTTP header value for these messages is sync. Because of network timing issues, it is possible to receive the sync message even before you receive the watch method response.

iOS local notification and calendar event does not appear while app is not running

I would like to share with someone who's stuck this like me,
here's Apple's troubleshooting, and it's really helpful:

my finally solution is the trigger time beyond 60s.

Issue with google calendar push notification

Google sends the response in the headers as an array.

Try this:

$response = apache_request_headers();

if($response) {

 print_r($response);

}else {

  echo 'The apache_request_headers() did not find any headers.'; //Or google is not sending any.   

}

You may also try:

getallheaders() 

if the apache_request_headers did not work.

Testing this can be difficult. You may want to set up a log that sends any data your page gets to a table on your database so that you can go back and inspect to see what type of progress you are making.
