Inserting Google Calendar Gives 403 Resolution Errors

Question

I am trying to create an event. My Google calendar lists events correctly, but when I try to insert an event, this results in an error. What am I doing wrong

Fatal error: Uncaught exception 'Google_Service_Exception' with message 'Error calling POST https://www.googleapis.com/calendar/v3/calendars/primary/events: (403) Insufficient Permission' in /Library/WebServer/Documents/vendor/google/apiclient/src/Google/Http/REST.php:110 Stack trace: #0 /Library/WebServer/Documents/vendor/google/apiclient/src/Google/Http/REST.php(62): Google_Http_REST::decodeHttpResponse(Object(Google_Http_Request), Object(Google_Client)) #1 [internal function]: Google_Http_REST::doExecute(Object(Google_Client), Object(Google_Http_Request)) #2 /Library/WebServer/Documents/vendor/google/apiclient/src/Google/Task/Runner.php(174): call_user_func_array(Array, Array) #3 /Library/WebServer/Documents/vendor/google/apiclient/src/Google/Http/REST.php(46): Google_Task_Runner->run() #4 /Library/WebServer/Documents/vendor/google/apiclient/src/Google/Client.php(590): Google_Http_REST::execute(Object(Google_Client), Object(Google_Http_Request)) #5 /Library/WebServer/Documents/vendor/google/apiclient/src/Google/Service in /Library/WebServer/Documents/vendor/google/apiclient/src/Google/Http/REST.php on line 110 

here is my code.

Answer 1

And I think I understood it

so when you request a token (area)

Google_Service_Calendar :: CALENDAR_READONLY

it creates a credential file in my tmp directory and all the tokens were from there. I had to remove this and restore tokens using this

Google_Service_Calendar :: CALENDAR

And then I managed to create events

thanks
