Google API name: E-learning email service

This API was made for our clients to send email from their website and used only by administrators, not by general public.
Email types: confirm registration, forgot password, access to online courses/exams, reminder about course/exam ends, custom emails, etc.

The Email service only has access to send emails, it can not view incoming emails.

The administrators of the website can allow the use of the Google API in the Email global settings admin menu. 

The Api asks permission from the administrator of the website to send email on their behalf.

In the end it shows that Gmail is connected. The partners can Disconnect any time just clicking on the red button.
