How to use Google API to get all Goals and Reminders that are marked as DONE

In Google Calendar it is possible to:

1.) Mark a Goal as "Did it":

2.) Mark a Reminder as "Mark as done":

3.) Mark a Task as "Mark complete":

I know that it is possible to use Google Tasks API to get a list of all Tasks marked as "complete" by checking the task.status string property and comparing it to "completed":

In the Google Calendar API, I only found "Events" - Goals are never mentioned and Reminders are only mentioned as "email / sms / popup" reminders for the events (which is not what I want).

I can't find the Google Keep API.

How can I get a list of all Goals and Reminders marked as "done"?

I am willing to work with anything: Google Calendar / Google Tasks / Google Keep

I would use any official or unofficial / open source API in either Javascript or Php.

I would appreciate any answer or suggestion, thank you!
