n8n Workflow: Generate and Schedule Social Media Posts with AI and Telegram Approval
This n8n workflow automates the creation of social media posts using an AI agent (GPT-4 via OpenRouter) and incorporates a human-in-the-loop approval process through Telegram before scheduling.
It's designed for content creators, marketers, or anyone who needs a streamlined way to generate engaging social media content and ensure it meets quality standards before publication.
What it does
This workflow performs the following key steps:
- Triggers on a Schedule: The workflow starts at predefined intervals (e.g., daily, weekly) to generate new content.
- Generates Social Media Post Ideas with AI: An AI Agent (configured to use GPT-4 via OpenRouter) is prompted to generate a set of social media post ideas.
- Parses AI Output: The AI's response, expected to be in a structured format (e.g., JSON), is parsed to extract individual post suggestions.
- Splits Posts for Individual Processing: Each generated post idea is treated as a separate item for individual review.
- Sends Posts for Telegram Approval: Each post is sent to a designated Telegram chat for review. The message includes the post content and interactive buttons for "Approve" or "Reject".
- Waits for Telegram Response: The workflow pauses, waiting for a user to interact with the Telegram message (approve or reject the post).
- Merges Approval Responses: Once all pending approvals are received for a batch of posts, the workflow merges the responses.
- Filters Approved Posts: Only posts that received an "Approve" signal from Telegram are allowed to proceed.
- Placeholder for Scheduling: Approved posts are then ready for a subsequent action, such as scheduling them to a social media platform. (Note: The current JSON does not include the final scheduling node, but it's the logical next step.)
Prerequisites/Requirements
To use this workflow, you will need:
- n8n Instance: A running n8n instance.
- Telegram Bot Token: A Telegram bot and its token configured to send and receive messages.
- OpenRouter API Key: An API key for OpenRouter to access large language models like GPT-4.
- AI Agent Configuration: The AI Agent node will need specific instructions (prompts) to generate the desired social media post content.
- Structured Output Parser Schema: A schema (e.g., Zod schema) to correctly parse the AI's structured output.
Setup/Usage
- Import the Workflow: Download the JSON content and import it into your n8n instance.
- Configure Credentials:
- Set up a Telegram credential using your bot token.
- Set up an OpenRouter credential using your API key.
- Configure Telegram Trigger:
- Ensure the "Telegram Trigger" node is configured to listen for responses from the correct chat ID where approval messages will be sent.
- Configure AI Agent:
- Edit the "AI Agent" node to include your specific prompt for generating social media posts. Define the desired tone, topics, and quantity.
- Ensure the "OpenRouter Chat Model" is selected and configured with your OpenRouter credential.
- Configure Structured Output Parser:
- Update the "Structured Output Parser" node with the correct schema that matches the expected JSON output format from your AI Agent.
- Configure Telegram Node:
- Update the "Telegram" node to send approval messages to the correct chat ID.
- Add Scheduling Node (Optional but Recommended):
- After the "If" node (which filters for approved posts), add a new node (e.g., a social media platform node like Twitter, Facebook, LinkedIn, or a Google Sheets node) to schedule or store the approved posts.
- Activate the Workflow: Once configured, activate the workflow to let it run on its schedule.

By Jameson KanakulyaAutomated UGC video generator with Gemini images and SORA 2
This workflow automates the creation of user-generated-content-style product videos by combining Gemini's image generation with OpenAI's SORA 2 video generation. It accepts webhook requests with product descriptions, generates images and videos, stores them in Google Drive, and logs all outputs to Google Sheets for easy tracking. Main Use Cases Automate product video creation for e-commerce catalogs and social media. Generate UGC-style content at scale without manual design work. Create engaging video content from simple text prompts for marketing campaigns. Build a centralized library of product videos with automated tracking and storage. How it works The workflow operates as a webhook-triggered process, organized into these stages: Webhook Trigger & Input Accepts POST requests to the /create-ugc-video endpoint. Required payload includes: product prompt, video prompt, Gemini API key, and OpenAI API key. Image Generation (Gemini) Sends the product prompt to Google's Gemini 2.5 Flash Image model. Generates a product image based on the description provided. Data Extraction Code node extracts the base64 image data from Gemini's response. Preserves all prompts and API keys for subsequent steps. Video Generation (SORA 2) Sends the video prompt to OpenAI's SORA 2 API. Initiates video generation with specifications: 720x1280 resolution, 8 seconds duration. Returns a video generation job ID for polling. Video Status Polling Continuously checks video generation status via OpenAI API. If status is "completed": proceeds to download. If status is still processing: waits 1 minute and retries (polling loop). Video Download & Storage Downloads the completed video file from OpenAI. Uploads the MP4 file to Google Drive (root folder). Generates a shareable Google Drive link. Logging to Google Sheets Records all generation details in a tracking spreadsheet: Product description Video URL (Google Drive link) Generation status Timestamp Summary Flow: Webhook Request → Generate Product Image (Gemini) → Extract Image Data → Generate Video (SORA 2) → Poll Status → If Complete: Download Video → Upload to Google Drive → Log to Google Sheets → Return Response If Not Complete: Wait 1 Minute → Poll Status Again Benefits: Fully automated video creation pipeline from text to finished product. Scalable solution for generating multiple product videos on demand. Combines cutting-edge AI models (Gemini + SORA 2) for high-quality output. Centralized storage in Google Drive with automatic logging in Google Sheets. Flexible webhook interface allows integration with any application or service. Retry mechanism ensures videos are captured even with longer processing times. --- Created by Daniel Shashko
