Automate Social Media with HeyGen and GPT-5: Publish Videos to TikTok, YouTube & Instagram

👥 Who is this for?

This workflow is designed for:

  • Content creators who want to scale their short-form video production
  • Marketing teams seeking consistent and automated publishing pipelines
  • Agencies managing multiple social accounts for clients
  • Entrepreneurs looking to save time by automating repetitive content tasks

💡 What problem is this workflow solving?

Publishing on multiple platforms like YouTube Shorts, TikTok, and Instagram is often:

  • Time-consuming (manual editing, caption writing, uploads)
  • Inconsistent (different requirements for each platform)
  • Prone to delays (switching between tools)

This workflow solves these issues by creating a fully automated video pipeline powered by GPT-5, HeyGen, and Blotato.

⚙️ What this workflow does

  1. Capture voice idea via Telegram
  2. Transcribe voice to text using OpenAI Whisper
  3. Generate a catchy title and caption with GPT-5
  4. Create an AI avatar video with HeyGen
  5. Save and organize assets in Google Drive and Google Sheets
  6. Upload final video to Blotato
  7. Auto-publish to:
    • YouTube Shorts
    • TikTok
    • Instagram
    • (Optional: Facebook, X/Twitter, LinkedIn, Pinterest, Threads, Bluesky)
  8. Update logs in Google Sheets
  9. Send a Telegram confirmation once published

🧰 Setup

Before using this workflow, ensure you have:

  1. A Telegram Bot connected to n8n for voice input
  2. An OpenAI API key for transcription (Whisper) and GPT-5 processing
  3. A HeyGen account & API key for avatar video generation
  4. A Google Drive & Google Sheets integration for storing assets and logs
  5. A Blotato account (Pro plan) with API access enabled
  6. Verified Community Nodes enabled in n8n Admin Panel
  7. Blotato node installed and credentials configured

🛠️ How to customize this workflow

  • Prompts → Adjust GPT-5 prompts to match your brand voice and niche
  • Avatars → Use custom avatars or voices via HeyGen configuration
  • Platforms → Activate only the social nodes you need (e.g., focus on TikTok & YouTube Shorts)
  • Approval steps → Add Telegram or Slack confirmation before publishing
  • Analytics → Extend the workflow to track engagement data in Google Sheets, Airtable, or Notion

This workflow turns a simple spoken idea into a viral-ready video — automatically generated, styled, and posted across your most important platforms.

n8n Workflow: Generate AI Avatar Videos with GPT & Publish to Social Media

This n8n workflow automates the process of generating AI avatar videos based on a Google Sheet, getting approval via Telegram, and then publishing them to social media platforms. It leverages AI models for content generation and video creation, streamlining a complex content production pipeline.

What it does

This workflow simplifies and automates the following steps:

  1. Triggers on Telegram Message: The workflow starts when a specific message is received in Telegram.
  2. Fetches Data from Google Sheets: It reads data from a specified Google Sheet, likely containing prompts or content for video generation.
  3. Generates AI Content (Thinking Tool): An AI "Think" tool is used to process the input, potentially generating scripts, ideas, or further instructions for the video.
  4. Generates AI Chat Model Response: An OpenAI Chat Model is used to generate conversational content, likely for the video script.
  5. Generates AI Video: An OpenAI node is used to generate the actual AI avatar video based on the generated content.
  6. Stores Video in Google Drive: The generated video is uploaded and saved to a designated folder in Google Drive.
  7. Sends Approval Request to Telegram: A message is sent to Telegram with the generated video link, requesting approval.
  8. Waits for Approval: The workflow pauses, waiting for a specific approval message from Telegram.
  9. Conditional Publishing:
    • If Approved: If the video is approved, it proceeds to the "Publish to Social Media" step (represented by an empty HTTP Request node, implying integration with social media APIs).
    • If Rejected: If the video is rejected, it sends a rejection notification to Telegram.
  10. Updates Google Sheet: The workflow updates the Google Sheet with the status of the video (e.g., "Approved", "Rejected", "Published").

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Telegram Account & Bot: A Telegram bot and a chat ID to send and receive messages for triggering and approvals.
  • Google Sheets Account: Access to a Google Sheet containing the input data and for status updates.
  • Google Drive Account: A Google Drive account to store the generated videos.
  • OpenAI API Key: An API key for OpenAI to utilize its Chat Model and potentially other AI capabilities for content and video generation.
  • Social Media Accounts: Credentials and API access for the social media platforms you intend to publish to (represented by the generic HTTP Request node). This will require further configuration.

Setup/Usage

  1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Telegram Bot credential for both the "Telegram Trigger" and "Telegram" nodes.
    • Configure your Google Sheets credential for the "Google Sheets" nodes.
    • Set up your Google Drive credential for the "Google Drive" node.
    • Configure your OpenAI API Key credential for the "OpenAI Chat Model" and "OpenAI" nodes.
  3. Customize Nodes:
    • Telegram Trigger (Node 50): Configure the trigger message or command that will initiate the workflow.
    • Google Sheets (Node 18): Specify the spreadsheet ID, sheet name, and any filters or ranges to read data from.
    • AI Agent (Node 1119), OpenAI Chat Model (Node 1153), OpenAI (Node 1250), Think (Node 1289): Configure the AI prompts, models, and parameters according to your content generation needs.
    • Google Drive (Node 58): Specify the folder where generated videos should be stored.
    • Telegram (Node 49): Configure the chat ID to send approval requests and notifications.
    • Wait (Node 514): Set the expected approval message from Telegram.
    • HTTP Request (Node 19): This node is currently a generic HTTP Request. You will need to configure it to interact with your desired social media platform's API for publishing. This might involve setting the URL, headers, body, and authentication.
    • Google Sheets (Node 18 - for updates): Configure the sheet and columns to update the video status.
  4. Activate the Workflow: Once all nodes are configured, activate the workflow.
  5. Trigger the Workflow: Send the configured trigger message to your Telegram bot to start the process.
  6. Approve/Reject Videos: Monitor your Telegram for approval requests and respond with the designated approval/rejection messages.

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. Key settings: Method: POST URL: https://<your-instance>.my.salesforce.com/services/data/v65.0/composite/sobjects Auth: salesforceOAuth2Api (predefined credential) Body (JSON): ={{ $json.body }} Output: Composite API results (per-record statuses). --- 11) Update File to One Drive Purpose: Archive the original PDF in OneDrive.

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.
