🧾 What this workflow does

This workflow automatically generates avatar-style videos from the latest AI-related news using Dumpling AI and HeyGen. It runs every hour, scrapes trending articles, turns them into 30–60 second spoken scripts with GPT-4o, and produces short avatar videos with HeyGen. Finally, it logs the final video URL in a Google Sheet.

👤 Who is this for

  • Newsletters and creators who want to automate AI trend updates
  • Content marketers generating short-form video content
  • Product teams experimenting with AI-generated summaries
  • Automation enthusiasts combining LLMs + video + trending data

⚙️ How to set up

🔐 Requirements

  • Dumpling AI API Key stored securely as HTTP Header credential
  • HeyGen API Key added as an HTTP Header credential
  • OpenAI API Key for GPT-4o (can use GPT-4o-mini if preferred)
  • Google Sheets account with one column: Video link

🛠 Step-by-step setup

  1. Google Sheet Setup

    • Create a Google Sheet with a single column named: Video link

  2. Update Credentials

    • Use n8n’s credential manager to add tokens for:
      • Dumpling AI
      • HeyGen
      • OpenAI
      • Google Sheets

  3. Optional Customizations

    • In the "Dumpling AI: Search AI News" node, you can change "query": "AI Agent"
      to other trending keywords (e.g., "Generative AI", "Autonomous Agents", etc.)
    • Update the avatar_id and voice_id in the HeyGen request to match your preferred look/sound

🧠 How it works

  1. The Schedule Trigger runs hourly.
  2. Dumpling AI searches for fresh news related to "AI Agent."
  3. The top 4 news links are scraped for full content.
  4. Articles are merged and fed into GPT-4o via a LangChain Agent to produce a casual, conversational video script.
  5. HeyGen creates a video using the script, avatar, and voice.
  6. The workflow waits until the video rendering is complete.
  7. Once done, the final video link is logged into Google Sheets.

🧪 Customization Ideas

  • Change the interval (e.g., every 6 hours, daily)
  • Swap avatar/voice in HeyGen to fit your brand
  • Expand to post the video directly to social media
  • Add image background or B-roll overlays using Creatomate

This is a fast, automated pipeline to create explainer-style AI news updates using real-time data and generative video tools.

Create AI News Avatar Videos with Dumpling AI, GPT-4o, and HeyGen

This n8n workflow automates the process of generating AI news avatar videos from a Google Sheet, using a combination of AI agents, large language models, and video generation services. It allows you to define news topics in a spreadsheet, automatically generate scripts and video content, and manage the video creation process.

What it does

This workflow streamlines the creation of AI-driven news videos through the following steps:

  1. Triggers on Schedule: Periodically checks for new news topics defined in a Google Sheet.
  2. Fetches News Topics: Reads a specified range from a Google Sheet to get the news topics.
  3. Filters for New Topics: Identifies topics that have not yet been processed for video creation.
  4. Generates News Script with AI: Uses an AI Agent (powered by an OpenAI Chat Model) to create a news script based on the fetched topic.
  5. Creates HeyGen Video: Sends the generated script to HeyGen to create an AI avatar video.
  6. Updates Google Sheet: Marks the processed news topic in the Google Sheet as "Done" and records the HeyGen video ID.
  7. Manages Rate Limits: Includes a Wait node to prevent hitting API rate limits for video generation.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Google Sheets Account: A Google account with access to Google Sheets.
    • Google Sheets Credential: An n8n credential configured for Google Sheets.
  • OpenAI Account: An OpenAI API key for the OpenAI Chat Model.
    • OpenAI Credential: An n8n credential configured for OpenAI.
  • HeyGen Account: An account with HeyGen for AI avatar video generation.
    • HeyGen API Key: An API key for HeyGen. This will likely be configured as an HTTP Request header or body parameter.
  • Dumpling AI: While the directory name suggests "Dumpling AI", the JSON does not explicitly show a dedicated node for it. It's possible "Dumpling AI" is integrated via the HTTP Request node or implied as part of the "AI Agent" setup (e.g., a custom tool). If it's a separate service, you might need its API key/credentials.

Setup/Usage

  1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Google Sheets: Set up your Google Sheets credential. Ensure it has access to the spreadsheet you intend to use.
    • OpenAI: Set up your OpenAI credential with your API key.
    • HeyGen: Configure the HTTP Request node (ID 19) with your HeyGen API key and any necessary authentication details (e.g., Bearer Token in headers, or API key in the request body).
  3. Prepare Google Sheet:
    • Create a Google Sheet with at least two columns: one for "News Topic" and another for "Status" (or similar).
    • The workflow expects to read from a specific range (e.g., Sheet1!A:B). Adjust the Google Sheets node (ID 18) to match your sheet name and range.
    • Initial "Status" for new topics should be empty or a specific value (e.g., "Pending") that the If node (ID 20) can check for.
  4. Customize AI Agent:
    • Review the AI Agent node (ID 1119) and OpenAI Chat Model node (ID 1153) to ensure the prompts and model settings are appropriate for generating your desired news scripts.
    • If "Dumpling AI" is a specific tool or model, ensure it's correctly configured within the AI Agent or the HTTP Request node.
  5. Activate Workflow: Once all credentials and configurations are set, activate the workflow. It will run on the defined schedule, processing new news topics and generating videos.
  6. Monitor: Keep an eye on the workflow execution and your Google Sheet to ensure videos are being generated and the sheet is updated correctly.

Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
