How to Create an OAuth Client ID in Google?

To create an OAuth client ID in Google, you need to follow these steps:

1. Go to the Google Cloud Console: Navigate to https://console.cloud.google.com/ and sign in with your Google account.
2. Create a project: If you don't have an existing project, create a new one.
3. Enable the necessary APIs: Search for and enable the Google APIs that you want to use with your OAuth client. For example, if you want to access Google Drive, enable the Google Drive API.
4. Create OAuth client ID:
   • Click on APIs & Services in the left navigation menu.
   • Select Credentials from the submenu.
   • Click on Create credentials and choose OAuth client ID.
   • Select the application type:
     • Web application: For web applications that access Google APIs.
     • Desktop application: For desktop applications that access Google APIs.
     • Installed application: For applications installed on a user's device.
     • Service account: For applications that need to access Google APIs on behalf of a user.
   • Fill in the required details, such as the application name and authorized redirect URIs.
   • Click Create.
5. Download the credentials: Once you have created the OAuth client ID, you will be able to download the client secret in JSON format. This file contains the client ID and client secret, which you will need to use in your application.

Example:

Let's say you want to create an OAuth client ID for a web application that will access Google Drive.

1. You would select Web application as the application type.
2. You would then provide the following details:
   • Name: "My Drive App"
   • Authorized redirect URIs: "http://localhost:8080/callback" (This is an example URI, you should replace it with the actual URI of your application's callback page.)
3. After clicking Create, you would be able to download the client secret in JSON format.

Practical Insights:

• Store the client secret securely: Never hardcode the client secret into your application. Instead, store it securely on your server.
• Use the correct OAuth flow: Different application types require different OAuth flows. Make sure you use the correct flow for your application.
• Test your application: Test your application thoroughly to ensure that it is working correctly.
