Sign in or create an account\n3. Navigate to **API Keys** section\n4. Click **Create new secret key**\n5. Copy the generated API key\n6. **Important**: Add billing information and credits to your OpenAI account\n\n#### Configure Both OpenAI Nodes:\n1. **OpenAI Chat Model1 (GPT-4o)**:\n   - Click on the node\n   - Click **Create New Credential**\n   - Select **OpenAI API**\n   - Paste your API key\n   - Save the credential\n\n2. **OpenAI Chat Model2 (GPT-4.1 Mini)**:\n   - Apply the same OpenAI API credential\n   - This handles result formatting\n\n### 4. Set Up Google Sheets Connection\n\n#### Create OAuth2 Credentials:\n1. Go to [Google Cloud Console](https://console.cloud.google.com/)\n2. Create a new project or select existing one\n3. Enable the **Google Sheets API**\n4. Go to **Credentials** → **Create Credentials** → **OAuth 2.0 Client IDs**\n5. Set application type to **Web Application**\n6. Add authorized redirect URIs (get this from n8n credentials setup)\n7. Copy the **Client ID** and **Client Secret**\n\n#### Configure in n8n:\n1. Click on the **Get Column Info2** node\n2. Click **Create New Credential**\n3. Select **Google Sheets OAuth2 API**\n4. Enter your **Client ID** and **Client Secret**\n5. Complete the OAuth flow by clicking **Connect my account**\n6. Authorize the required permissions\n\n### 5. Prepare Your Google Sheet\n\n#### Option A: Use the Sample Data Sheet\n- Access the pre-configured sheet: [Sample Marketing Data](https://docs.google.com/spreadsheets/d/19aUQYZq02qHsCelO4eeV4sx_MTJJupC5qe0gDLQBtRA/edit?usp=drivesdk)\n- Make a copy to your Google Drive\n- **Important**: Set sharing to \"Anyone with the link can view\"\n\n### 6. Configure Sheet References\n\n1. **Get Column Info2 Node**:\n   - Set **Document ID** to your Google Sheet ID\n   - Set **Sheet Name** to your columns metadata sheet (e.g., \"Columns\")\n   - This provides the AI with column letter mappings\n\n2. **HTTP Request Node**:\n   - No configuration needed - it uses dynamic URLs from the AI agent\n   - Ensure your sheet has proper sharing permissions\n\n### 7. Update System Prompt (If Using Custom Sheet)\n\nIf using your own Google Sheet, update the system prompt in the **AI Agent3** node:\n1. Replace the URL in the system message with your Google Sheet URL\n2. Update the GID (sheet ID) to match your data sheet\n3. Keep the same query structure format\n"
