Stop writing product titles by hand. Generate and publish product titles and descriptions for Print on Demand products using a simple Google Sheet. Ideal for ecommerce teams that want faster listing updates with clear brand voice.

On a manual run, the flow pulls your Printify shops and products, then breaks them into batches. Brand rules are set once, and OpenAI writes multiple title and description options for each product. Options are saved to Google Sheets so your team can review and choose. When the upload column changes, a Google Sheets event pushes the selected copy back to Printify using an API update. The LLM can also use Wikipedia and a calculator tool to enrich copy with facts or quick math.

You need a Printify API token, a Google Sheet, and an OpenAI API key. Update the brand guidelines and set how many options to create before running it on your catalog. Expect faster product refreshes, consistent tone, and better SEO on product pages. Great for seasonal launches, bulk edits, and testing copy across many items.

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You'll need accounts with Google Sheets, Printify, OpenAI and Wikipedia. See the Tools Required section above for links to create accounts with these services.
3. In the n8n credentials manager, create Google Sheets OAuth2 credentials. Double click a Google Sheets node, choose 'Credential to connect with', click 'Create new credential', and follow the prompts to approve access to your Google account.
4. Create Printify credentials as HTTP Header Auth. Open your Printify account to create an API token, then in n8n choose 'HTTP Header Auth', set Header Name to 'Authorization' and Value to 'Bearer YOUR_TOKEN'. Save and test.
5. Create OpenAI credentials. In your OpenAI account, generate an API key. In n8n, open the OpenAI node, click 'Create new credential', paste the API key, and save.
6. Open the Set node named Brand Guidelines and enter your brand name, tone, keywords, and any custom instructions you want the AI to follow.
7. In the Number of Options node, set how many title and description options you want for each product.
8. Configure the Google Sheets Trigger node. Set Document ID and Sheet name to your sheet. Make sure the trigger watches the 'upload' column as shown in node options.
9. Run a test: click Test workflow to pull Printify products. Confirm the GS Add Product Option and Update Product Option nodes write option rows into your Google Sheet.
10. Pick a product in the sheet, copy the preferred option into product_title and product_desc, then change the upload cell to TRUE. Wait up to one minute and verify the Printify product updates.
11. Troubleshoot: if products do not appear, check the Printify token and shop access. If updates fail, confirm product_id matches Printify and your header auth is correct. Review execution logs, and reduce batch size if you see rate limits.
