n8n Workflow: YouTube to Social Media Content with Vizard.ai and GPT-4

This n8n workflow automates the process of transforming YouTube videos into social media content using Vizard.ai for video processing and OpenAI's GPT-4 for text generation. It's designed to streamline content creation for marketers, creators, and businesses looking to repurpose long-form video into engaging short-form content.

What it does

This workflow performs the following key steps:

  1. Triggers Manually: The workflow is initiated manually, allowing you to control when the content generation process begins.
  2. Fetches YouTube Video URLs: It reads a list of YouTube video URLs from a specified Google Sheet.
  3. Limits Processing: It processes a limited number of videos at a time to manage API usage and workflow execution.
  4. Loops Through Videos: For each YouTube video URL:
    • It sends the YouTube video URL to Vizard.ai for processing.
    • It waits for a short period to allow Vizard.ai to begin processing.
    • It retrieves the processed video data from Vizard.ai.
    • It extracts relevant text content from the Vizard.ai response.
    • It uses OpenAI (likely GPT-4, given the directory name context) to generate social media content (e.g., captions, tweets, short summaries) based on the extracted text.
    • It sends an email notification with the generated content or a summary.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Google Sheets Account: Configured credentials for Google Sheets to read YouTube video URLs.
  • Vizard.ai Account: An API key or credentials for Vizard.ai to process videos.
  • OpenAI Account: An API key for OpenAI (e.g., GPT-4) to generate text content.
  • Gmail Account: Configured credentials for Gmail to send email notifications.

    • Download the provided JSON file for this workflow.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the "Import from JSON" button and paste the workflow JSON or upload the file.
  2. Configure Credentials:
    • Locate the "Google Sheets" node and configure your Google Sheets credentials. Specify the spreadsheet name and sheet name where your YouTube video URLs are listed.
    • Locate the "HTTP Request" nodes that interact with Vizard.ai and configure the necessary API keys or authentication headers.
    • Locate the "OpenAI" node and configure your OpenAI API key.
    • Locate the "Gmail" node and configure your Gmail credentials.
  3. Customize Workflow (Optional):
    • Google Sheets: Adjust the "Google Sheets" node to point to your specific spreadsheet and sheet containing YouTube video URLs. Ensure the column containing URLs is correctly referenced.
    • Limit: Modify the "Limit" node if you want to process more or fewer videos in a single execution.
    • Vizard.ai Integration: Review the "HTTP Request" nodes for Vizard.ai to ensure they match the current Vizard.ai API documentation for submitting videos and checking status.
    • OpenAI Prompt: Customize the prompt in the "OpenAI" node to refine the type and style of social media content generated (e.g., "Generate 3 Twitter threads," "Write a LinkedIn post summarizing the video").
    • Gmail Notification: Adjust the "Gmail" node to send notifications to your preferred email address and customize the email subject and body with the generated social media content.
    • Wait Time: Adjust the "Wait" node duration if Vizard.ai processing typically takes longer or shorter.

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?
