Go to [OpenAI's website](https://platform.openai.com/api-keys)\n2. Create an account or sign in\n3. Navigate to \"API Keys\" in your dashboard\n4. Click \"Create new secret key\"\n5. Copy the API key and save it securely\n6. In n8n, go to **Credentials** \u2192 **Add Credential** \u2192 **OpenAI API**\n7. Paste your API key and save as \"OpenAI account\"\n\n### Step 2: Set Up GotoHuman Credentials\n\n1. Visit [GotoHuman](https://gotohuman.com/) and create an account\n2. Navigate to your API settings/dashboard\n3. Generate an API key\n4. In n8n, go to **Credentials** \u2192 **Add Credential** \u2192 **GotoHuman API**\n5. Enter your API credentials and save as \"gotoHuman account\"\n\n### Step 3: Configure the Review Template\n\n1. In your GotoHuman dashboard, create a new review template with ID: `3473LaRDbdf03sd6uzYG`\n2. Set up the template with:\n - **Image field**: For displaying the generated image\n - **Prompt field**: For showing the original prompt\n - **Review options**: Approve/Reject buttons\n3. Configure reviewers and notification settings\n\n### Step 4: Import and Configure the Workflow\n\n1. Copy the provided workflow JSON\n2. In n8n, click **Import from File** or **Import from Clipboard**\n3. Paste the workflow JSON\n4. The workflow will automatically create the following nodes:\n\n#### Node Configuration Details:\n\n##### Start Workflow (Manual Trigger)\n- No configuration needed\n- Used to manually start the workflow\n\n##### Set Image Prompt\n- **Prompt**: \"Make an image of an attractive person standing in new york city\"\n- **Name**: \"woman-nyc\"\n- *Customize these values for your specific use case*\n\n"
