Optimize and Update Printify Product Titles and Descriptions

This n8n workflow automates the process of generating optimized titles and descriptions for Printify products using AI, based on data from a Google Sheet. It allows for manual execution or can be triggered by changes in the Google Sheet.

What it does

This workflow streamlines your Printify product optimization by:

  1. Triggering the workflow: It can be executed manually or automatically when new or updated data is detected in a specified Google Sheet.
  2. Reading Product Data: Fetches product information (likely existing title, description, and keywords) from a Google Sheet.
  3. Generating Optimized Content: Utilizes an OpenAI model to generate new, optimized titles and descriptions based on the input data. It can also leverage a calculator and Wikipedia tool for enhanced content generation.
  4. Conditional Processing: Checks if the generated content is valid and proceeds only if it meets certain criteria.
  5. Updating Printify (Placeholder): The workflow is designed to update Printify products with the new title and description. Note: The current JSON does not contain a direct Printify update node, but an HTTP Request node is present, which would typically be configured for this purpose.
  6. Looping for Batch Processing: Processes multiple product items in batches to handle large datasets efficiently.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • Google Sheets Account: Configured with credentials in n8n to access your product data spreadsheet.
  • OpenAI API Key: Configured as a credential in n8n for the OpenAI node.
  • Printify Account: Although not explicitly configured in the provided JSON, a Printify account would be necessary for the intended update functionality.
  • Google Sheet: A Google Sheet containing your Printify product data, including columns for existing titles, descriptions, and any other relevant information for optimization.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Google Sheets Credentials:
    • Open the "Google Sheets Trigger" and "Google Sheets" nodes.
    • Set up your Google Sheets credentials (OAuth2 recommended) to allow n8n to read from your spreadsheet.
    • Specify the Spreadsheet ID and Sheet Name where your product data is located.
  3. Configure OpenAI Credentials:
    • Open the "OpenAI" node.
    • Set up your OpenAI API Key credential in n8n.
  4. Configure HTTP Request Node (Printify Update):
    • Open the "HTTP Request" node.
    • Crucially, configure this node to interact with the Printify API. This will involve:
      • Setting the URL to the appropriate Printify API endpoint for updating products.
      • Setting the HTTP Method (likely PUT or POST).
      • Configuring Headers for authentication (e.g., Authorization with your Printify API key).
      • Mapping the Body to send the optimized title and description to Printify, along with the product ID.
  5. Review and Customize Nodes:
    • Sticky Note (ID 565): Contains a note, likely providing context or instructions. Review its content.
    • Code (ID 834): This node might contain custom logic for data manipulation or formatting. Review its JavaScript code to understand its function.
    • Edit Fields (Set) (ID 38): This node is used for data transformation. Inspect its configuration to see how data fields are being modified or added.
    • Loop Over Items (Split in Batches) (ID 39): Adjust the batch size if needed based on API rate limits or desired processing speed.
    • If (ID 20): Review the conditions in this node to understand when the workflow branches or proceeds.
    • Calculator (ID 1195) and Wikipedia (ID 1201): These nodes are currently present but not directly connected in the provided JSON. If you intend to use them for enriching product data (e.g., calculating optimal pricing, gathering product-related information), you will need to connect them appropriately and configure their inputs/outputs.
  6. Activate the Workflow: Once configured, activate the workflow. You can then trigger it manually using the "Manual Trigger" node or allow the "Google Sheets Trigger" to run it automatically based on your sheet changes.

Automate Dutch Public Procurement Data Collection with TenderNed

TenderNed Public Procurement What This Workflow Does This workflow automates the collection of public procurement data from TenderNed (the official Dutch tender platform). It: Fetches the latest tender publications from the TenderNed API Retrieves detailed information in both XML and JSON formats for each tender Parses and extracts key information like organization names, titles, descriptions, and reference numbers Filters results based on your custom criteria Stores the data in a database for easy querying and analysis Setup Instructions This template comes with sticky notes providing step-by-step instructions in Dutch and various query options you can customize. Prerequisites TenderNed API Access - Register at TenderNed for API credentials Configuration Steps Set up TenderNed credentials: Add HTTP Basic Auth credentials with your TenderNed API username and password Apply these credentials to the three HTTP Request nodes: "Tenderned Publicaties" "Haal XML Details" "Haal JSON Details" Customize filters: Modify the "Filter op ..." node to match your specific requirements Examples: specific organizations, contract values, regions, etc. How It Works Step 1: Trigger The workflow can be triggered either manually for testing or automatically on a daily schedule. Step 2: Fetch Publications Makes an API call to TenderNed to retrieve a list of recent publications (up to 100 per request). Step 3: Process & Split Extracts the tender array from the response and splits it into individual items for processing. Step 4: Fetch Details For each tender, the workflow makes two parallel API calls: XML endpoint - Retrieves the complete tender documentation in XML format JSON endpoint - Fetches metadata including reference numbers and keywords Step 5: Parse & Merge Parses the XML data and merges it with the JSON metadata and batch information into a single data structure. Step 6: Extract Fields Maps the raw API data to clean, structured fields including: Publication ID and date Organization name Tender title and description Reference numbers (kenmerk, TED number) Step 7: Filter Applies your custom filter criteria to focus on relevant tenders only. Step 8: Store Inserts the processed data into your database for storage and future analysis. Customization Tips Modify API Parameters In the "Tenderned Publicaties" node, you can adjust: offset: Starting position for pagination size: Number of results per request (max 100) Add query parameters for date ranges, status filters, etc. Add More Fields Extend the "Splits Alle Velden" node to extract additional fields from the XML/JSON data, such as: Contract value estimates Deadline dates CPV codes (procurement classification) Contact information Integrate Notifications Add a Slack, Email, or Discord node after the filter to get notified about new matching tenders. Incremental Updates Modify the workflow to only fetch new tenders by: Storing the last execution timestamp Adding date filters to the API query Only processing publications newer than the last run Troubleshooting No data returned? Verify your TenderNed API credentials are correct Check that you have setup youre filter proper Need help setting this up or interested in a complete tender analysis solution?
