Digest new YouTube videos to Slack with Google Sheets, RapidAPI & GPT-4o-mini
Who is this for?
Marketing, content, and enablement teams that need a quick, human-readable summary of every new video published by the YouTube channels they care about—without leaving Slack.
What problem does this workflow solve?
Manually checking multiple channels, skimming long videos, and pasting the highlights into Slack wastes time. This template automates the whole loop: detect a fresh upload from your selected channels → pull subtitles → distill the key take-aways with GPT-4o-mini → drop a neatly-formatted digest in Slack.
What this workflow does
- Schedule Trigger fires every 10 min, then grabs a list of YouTube RSS feeds from a Google Sheet.
- HTTP + XML fetch & parse each feed; only brand-new videos continue.
- YouTube API fetches title/description, RapidAPI grabs English subtitles.
- Code nodes build an AI payload; OpenAI returns a JSON summary + article.
- A formatter turns that JSON into Slack Block Kit, and Slack posts it.
- Processed links are appended back to the “Video Links” sheet to prevent dupes.
Setup
- Make a copy of this Google Sheet and connect a Google Sheets OAuth2 credential with edit rights.
- Slack App: create → add
chat:write,channels:read,app_mention; enable Event Subscriptions; install and store the Bot OAuth token in an n8n Slack credential. - RapidAPI key for
https://yt-api.p.rapidapi.com/subtitles(300 free calls/mo) → save as HTTP Header Auth. - OpenAI key → save in an OpenAI credential.
- Add your RSS feed URLs to the “RSS Feed URLs” tab; press Execute Workflow.
How to customise
- Adjust the schedule interval or freshness window in “If newly published”.
- Swap the OpenAI model or prompt for shorter/longer digests.
- Point the Slack node at a different channel or DM.
- Extend the AI payload to include thumbnails or engagement stats.
Use-case ideas
- Product marketing: Instantly brief sales & CS teams when a competitor uploads a feature demo.
- Internal learning hub: Auto-summarise conference talks and share bullet-point notes with engineers.
- Social media managers: Get ready-to-post captions and key moments for re-purposing across platforms.
n8n Workflow: Digest New YouTube Videos to Slack with Google Sheets, RapidAPI, and GPT-4o-mini
This n8n workflow automates the process of discovering new YouTube videos from specified channels, filtering out already processed videos, generating AI-powered summaries, and posting a digest to Slack. It leverages Google Sheets for state management, a generic HTTP Request for external API calls, and OpenAI for content summarization.
What it does
This workflow performs the following key steps:
- Triggers on Schedule: The workflow runs on a predefined schedule (e.g., daily, hourly) to check for new videos.
- Fetches Latest Videos: It queries the YouTube API for the latest videos from configured channels.
- Parses XML Data: Converts the XML response from the YouTube API into a structured JSON format.
- Filters Existing Videos: Compares newly found videos against a Google Sheet to identify and filter out any videos that have already been processed and shared.
- Loops Through New Videos: Processes each new video individually.
- Generates AI Summary: For each new video, it uses an OpenAI Chat Model (GPT-4o-mini) to generate a concise summary of the video's title and description.
- Formats Output: Structures the video information and AI summary into a readable format.
- Posts to Slack: Sends a digest message containing the new video's title, link, and AI summary to a designated Slack channel.
- Updates Google Sheet: Records the newly processed video's ID in the Google Sheet to prevent future reprocessing.

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?

By higashiyama 🎓 How to transform unstructured email data into structured format with AI agent
This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From – sender’s email address To – recipient’s email address Subject – email subject line Summary – short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits ✅ Full Automation: Eliminates manual reading and data entry from incoming emails. ✅ Multi-Source Integration: Handles data from different email providers seamlessly. ✅ AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. ✅ Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. ✅ Time Efficiency: Processes emails in real time, improving productivity and response speed. *✅ Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?
