Step 2: Sign in and Navigate to API Keys

Sign in with your Google account, then look for the "Get API key" button or navigate to the API keys section. This is usually prominently displayed on the main dashboard.

💡 Pro Tip

Make sure you're using a Google account that you'll remember, as your API keys will be tied to this account.

Once you're logged in, look for the "Get API key" button or navigate to the API keys section. This is usually prominently displayed on the main dashboard.

You should see something like:

  • A button labeled "Get API key" or "Create API key"
  • An "API keys" section in the sidebar or navigation menu
  • A prompt asking if you want to create your first API key

Step 3: Create Your API Key

Click on "Create API key" and you'll see a dialog box. Choose "Create API key in new project" for the simplest setup, or select an existing Google Cloud project if you have one.

⚠️ Important

Your API key will only be shown once. Make sure to copy and save it securely!
