4. GSuite Special Key Generation

The very first step should be to create and set up a GCloud Console Project. Following are the steps to do so:

Go to: https://console.cloud.google.com
Login using the super admin credentials.
Once logged in, click the top navbar project selector, you will see an option to create a “New Project” in the panel that shows up once you click the project selector.
Enter the project name, organization, and location and create the project.

Then the next step is to create a service account, use the following steps to do so:

Make sure that you have selected the newly created project from the project selector on the top navbar.
Once selected, from the left menu, under “APIs & Services” select “Credentials”.
Click “Manage Service Account” and under the Service Accounts page, click the “Create Service Account” button on the top.
Give a proper name to the service account (Our code should not affect the name that is used).
It will pre-fill email, update in case you want to change as this would not affect our code.
Enter a proper description, again this should not affect the code.
Click “Create”
Once created, it will ask to select a Role, select Project > Owner as the role, and click Continue.
The next step is to grant service account access, there are 2 text boxes, in both the text boxes, enter the super admin account email id and click “Done”.
Once created, it will take you to the Service Account Manage page where the newly created Service Account will be listed.
Click on the Service Account and it will take you to the Service Account Details page. Click Edit to start editing the account.
Once saved, under the Keys section, Create a new key, use JSON format. Make sure you download the key as it would not let you download the key later.
On the Service Account Details page, make sure you copy the Unique Id shown on that page as we will need it later (It will look something similar to '117173051217199643714')

Now it’s time to set up the libraries, use the following steps to set it up:

Make sure that you have selected the newly created project from the project selector on the top navbar.
Once selected, from the left menu, under “APIs & Services” select “Library”.
Enable the following APIs for our project:

Once enabled you will see the enabled list under APIs & Services > Dashboard.
