Answer

Solution

In order to create the conference data property in an Event you will have to send a request with the ConferenceDataVersion flag activated.

conferenceDataVersion : Version number of conference data supported by the API client. Version 0 assumes no conference data support and ignores conference data in the event’s body. Version 1 enables support for copying of ConferenceData as well as for creating new conferences using the createRequest field of conferenceData. The default is 0. Acceptable values are 0 to 1, inclusive.

To pass this setting in PHP you can use the following instruction:

 $service->events->insert($calendarId, $event, ['conferenceDataVersion' => 1]);      

When setting this flag you will also have to create an Event property called conferenceData.createRequest

The conference-related information, such as details of a Google Meet conference. To create new conference details use the createRequest field. To persist your changes, remember to set the conferenceDataVersion request parameter to 1 for all event modification requests.

Example:

"conferenceData" => [
        "createRequest" => [
          "conferenceSolutionKey" => [
            "type" => "hangoutsMeet"
          ],
          "requestId" => "123"
        ]
      ]
