In order to establish a connection with Google Meet, it is necessary to generate Google Credentials beforehand. This can be accomplished by accessing the Google Developer Console.

By simply following the steps outlined below, it is easy to obtain API keys.
From the top left corner, select a project to use for credentials. If you do not have a project created, please follow along.

After assigning a name to the project and, if necessary, choosing an organization, the project will be designated as yours.

From Quick Access select “APIs & Services”:

Alternatively, you can access “APIs & Services” through the Navigation menu:

From opened Dashboard, click Enable APIs and Services.

Type the “Google Calendar” into the search field of the Google API Library to initiate a search.

Select the Google Calendar API from the search results:

To activate the Google Calendar API for this project, simply click on the Enable button.

From the Google Calendar API dashboard click on the “Create Credentials” button:

Choose “User data” as the data type and proceed by clicking on the Next button.

In the section for the “OAuth Consent Screen”, provide the name of your application and include your User support email and Developer Contact email.

Upon saving the App details, you will be directed to the “Scopes” section, which can be skipped:

After that, you can select the OAuth Client ID. Select Web application as your application type. Subsequently, you will need to establish an Authorized redirect URI.

For the “Authorized redirect URI” go back to your WordPress admin dashboard.
You will find a link to copy in the 2nd step of the Google Meet setup wizard in MS LMS > Google Meet.

Instructors can get the URL in the second step of the Google Meet setup wizard on their User Account:

Copy that link and go back to the Google developer console and paste the link in the designated area for the Authorized redirect URI.

This serves as the redirect URI required by the Google Calendar API. Click on the Save button, and once you do that, you will have finished the task.
After creating the credentials, you can then download the JSON file from the credentials dashboard. Simply click on the download icon to continue.

Finally, access the OAuth consent screen section and select the option to Publish the app.

By doing so, you will enable the authorization for GSourcers and Google to utilize this integration. This step holds significant importance, as neglecting it could result in encountering an error.
Therefore, ensure that you perform this step diligently.
