An authenticated connection to Google is required in order to access emails, or files from Google Drive. This guide is a walk-through to establish an OAuth application connection, based up on Googles interface in the year 2022.

The following prerequisites must be fulfilled for a successful connection to the Google authentication service:

• The i-net CoWork server must be secured with HTTPS
• The i-net CoWork server and browser client must be able to reach https://accounts.google.com/ and https://oauth2.googleapis.com/
• You have to be authorized to create an API and Service Login at https://console.cloud.google.com/
• The OAuth approval screen must be set and published correctly.

If an e-mail retrieval or dispatch is initiated with this profile, the following requirements must be met:

• The server must be able to call the following domains: smtp.gmail.com, imap.gmail.com.

You are about to create a GCP API and Service login now. This login will provide the authentication credentials for the OAuth connection we want to add to i-net CoWork.

• Go to https://console.cloud.google.com/apis/credentials and log in
• Make sure, you have selected the appropriate project in the title bar of the interface, or create a new project
• Click Create Login in the menu, then select Oauth Client ID
• Select Web Application as the Application Type
• Enter a Name describing the application
• Add an Authorized Redirection URL and enter the value displayed in the configuration dialog of the i-net CoWork server, where a new connection is created
• Click Create

You have now create the login application. A dialog with the required information is displayed and you can download it as JSON file.

• Copy & Paste the Your Client ID into the Client ID field of the OAuth Connection dialog in the i-net CoWork configuration
• Copy & Paste the Your Client Key into the Secret ID field of the OAuth Connection dialog in the i-net CoWork configuration

Note: The Secret ID is considered a password, so please keep it in a safe place.
