Proceed with selecting the desired Authentication Type. Then select API Base URL (in most cases default one is the right one).

More info is available in Authentication section.

User Account [OAuth]

Steps to get Google Calendar Credentials

To make this work you will have to create an OAuth application. To register an App, perform the following steps (Detailed steps found in the help link at the end):

Go to Google API Console
From the Project Dropdown (usually found at the top bar) click Select Project
On Project Propup click CREATE PROJECT
Once project is created you can click Select Project to switch the context (You can click on Notification link or Choose from Top Dropdown)
Click ENABLE APIS AND SERVICES
Now we need to enable Google Drive API.
Search Google Drive API. Select and click ENABLE
Go to back to main screen of Google API Console
Click OAuth Concent Screen Tab. Enter necessary details and Save.
Click Credentials Tab
Click CREATE CREDENTIALS (some where in topbar) and select OAuth Client ID option.
When prompted Select Application Type as Desktop App and click Create to receive your ClientID and Secret. Later on you can use this information now to configure Connection with UseCustomApp=true.
Go to OAuth Consent Screen tab. Under Publishing Status click PUBLISH APP to ensure your refresh token doesnt expire often. If you planning to use App for Private use then do not have to worry about Verification Status after Publish.

Service Account (Using Private Key File) [OAuth]

Steps to get Google Calendar Credentials
Use these steps to authenticate as service account rather than Google / GSuite User. Learn more about service account here

Basically to call Google API as Service account we need to perform following steps listed in 3 sections (Detailed steps found in the help link at the end)

Create Project

First thing is create a Project so we can call Google API. Skip this section if you already have Project (Go to next section)

Go to Google API Console
From the Project Dropdown (usually found at the top bar) click Select Project
On Project Propup click CREATE PROJECT
Once project is created you can click Select Project to switch the context (You can click on Notification link or Choose from Top Dropdown)
Click ENABLE APIS AND SERVICES
Now we need to enable API - Google Calendar API
Search Drive. Select and click ENABLE

Create Service Account

Once Project is created and APIs are enabled we can now create a service account under that project. Service account has its ID which looks like some email ID (not to confuse with Google /Gmail email ID)

Go to Create Service Account
From the Project Dropdown (usually found at the top bar) click Select Project
Enter Service account name and Service account description
For Role, do not select anything for now and Click Continue and then click Done. Next we will create Key.

Create Key

Once service account is created we need to create key file (i.e. credentials).

In the Cloud Console, click the email address for the service account that you created.
Click Keys.
Click Add key, then click Create new key.
Click Create and select P12 format. A P12 key file is downloaded to your computer. We will use this file in our API connection.
Click Close.
Now you may use downloaded *.p12 key file as secret file and Service Account Email as Client ID (e.g. some-service-account-name@your-project-id.iam.gserviceaccount.com ).

Add Permission

Now last thing is give read/write permission to Service Account for Calendar you like to access using API.

Copy the email address of your service account we created in previous step (its usually like this some-service-account-name@your-project-id.iam.gserviceaccount.com).
Login to https://calendar.google.com/calendar and make sure you see the calendar you like to access via API
On the left, find the "My calendars" section. To expand it, click the Down arrow Down arrow.
Hover over the calendar you want to share, and click 3 dots next to it. Click "Settings and sharing".
Find "Share with specific people", Click Add people button and enter the service account email id we obtained in the previous section.
Select correct permission you like to give for sharing. Click Send button to share. Thats it now we can read / write Calendar Events using Service account approach.
