This article provides a complete, practical walkthrough of the Manual Youtube Create Triggered n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   Automate YouTube Video Descriptions Using n8n: A Smart Workflow for Content Creators
   
   In the digital era, consistency and automation are key for content creators aiming to stand out and save time. Whether you're a solo entrepreneur or managing a full-scale media channel, small tasks such as updating video descriptions can become tedious when multiplied across dozens—or hundreds—of videos. Fortunately, tools like n8n (a powerful node-based workflow automation platform) allow creators to eliminate repetitive tasks and focus on what truly matters: creating great content.
   
   In this article, we explore a robust n8n workflow created by experienced automation builder Emmanuel from n8n.ninja. This workflow connects to your YouTube channel and automatically updates all existing video descriptions with your custom branding, links, and promotional call-to-actions—without disturbing your existing video text.
   
   Let’s dive into how this automation works, what it accomplishes, and why it's a game-changer for YouTube content creators.
   
   🧠 What Does the Workflow Do?
   
   This n8n workflow streamlines the process of updating your video descriptions across your entire YouTube channel by appending a predefined block of content (such as branded call-to-action links, social profiles, or personal notes) to the existing ones.
   
   Here’s how it works at a high level:
   
   - The workflow first retrieves all your YouTube videos.
   - Then, it inspects each video’s description for a designated delimiter (in this case, "--- n8ninja ---").
   - It trims any older appended content beneath the delimiter if present.
   - It appends the most current predefined description to the existing one.
   - Lastly, it checks if the resulting description differs from the current one on YouTube. If so, it updates it.
   
   This ensures your video descriptions stay clean, uniform, and up to date—while preserving each video's unique content above the delimiter.
   
   ⚙️ Step-by-Step Breakdown
   
   Let’s take a closer look at each node in this workflow and what it does:
   
   1. Manual Trigger 
   
   The workflow starts manually (although you can later configure it with a scheduler) using the “Manual Trigger” node.
   
   2. Config Node
   
   This node stores two important values:
   
   - The splitter: A unique delimiter string (e.g., "--- n8ninja ---") used to separate the original video description from your appended branded message.
   - The description: This is the message you want to consistently apply to all your videos. In Emmanuel's case, it includes a call-to-action to try n8n, links to his site/socials, and a bit of personal branding.
   
   3. List All Videos
   
   This node, powered by the YouTube Data API, fetches a full list of videos from your authenticated YouTube account. Each video is individually evaluated and processed by subsequent nodes.
   
   4. Generate Description
   
   Here's where the automation magic begins. This node:
   
   - Extracts the original portion of a description by splitting it at the predefined delimiter.
   - Reappends the unchanged upper portion with the current version of the branding text block.
   
   For example, if the existing description looks like:
   
   My awesome video content  
   --- n8ninja ---  
   (link to social media)
   
   It trims everything after the delimiter and adds the latest description from the Config node below it.
   
   5. Check if Has Changed
   
   Before updating any video, this node compares the newly generated description with the existing one uploaded on YouTube. Only if a change is detected does the workflow proceed to update the video. This built-in logic prevents unnecessary API calls and saves resources.
   
   6. Update Description
   
   If the changes are confirmed, the workflow uses the YouTube Update node to overwrite the video’s description using the YouTube Data API call, ensuring your most recent branding or links stay current across all content.
   
   💡 Why Use This Automation?
   
   Here are a few reasons why this workflow is a top-tier addition to your YouTube content management strategy:
   
   - Time-Saving: Update hundreds of videos in a single run.
   - Consistency: Prevent forgotten or outdated CTAs.
   - Automation: Set it on a schedule to keep content fresh and links up-to-date.
   - Scalability: Adaptable for growing channels with large video libraries.
   
   🌐 Supported API Integration
   
   This workflow leverages the following external API:
   
   - YouTube Data API: Used to list videos and update metadata. Authentication is handled securely via OAuth2 credentials configured inside n8n.
   
   🚀 How to Use This Workflow
   
   1. Connect your YouTube account in n8n using OAuth2 credentials.
   2. Configure the “Config” node with your custom description and delimiter.
   3. Run the workflow manually or configure a time-based trigger for regular updates.
   4. Sit back and relax knowing your video descriptions are always up-to-date.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
