This article provides a complete, practical walkthrough of the Splitout Code Automation Webhook 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.

   Automating Image-rich Posts to Bluesky with n8n: A Step-by-Step Guide
   
   As social media automation becomes increasingly important for creators and developers, platforms like Bluesky are opening the doors to programmatic content creation and management. Using a powerful low-code automation tool like n8n, you can significantly streamline your content workflow—especially if you're consistently posting similar content across multiple platforms.
   
   In this article, we’ll walk through an example n8n workflow specifically designed for posting image-rich content to Bluesky. Whether you're a developer trying to scale content delivery or a creator looking to experiment with automation, this walkthrough will guide you through the process—from setting credentials to successfully publishing a post with embedded images.
   
   Overview of the Workflow
   
   The workflow centers around creating a new post on Bluesky, complete with text content and up to four embedded images. Rather than handling uploads and JSON manually, this no-code/low-code setup uses visual nodes in n8n to define the logic, retrieve images, and interact with the Bluesky API.
   
   Here’s the high-level process:
   
   1. Trigger the automation manually.
   2. Define Bluesky login credentials.
   3. Initiate a Bluesky session.
   4. Set the desired caption for your post.
   5. Define and fetch image URLs.
   6. Upload each image as a “blob” to the Bluesky servers.
   7. Structure the post to include both the caption and images.
   8. Publish it to your Bluesky feed.
   
   Let’s dive deeper into each step.
   
   Step 1: Triggering the Workflow
   
   The process starts with a “Manual Trigger” node. This is useful for testing and allows you to initiate the automation whenever you want by clicking 'Test workflow' in the n8n editor.
   
   Step 2: Defining Credentials
   
   To interact with Bluesky securely, you must authenticate first. This workflow uses a Set node labeled “Define Credentials” where your identifier (such as username.bsky.social) and a non-standard application password (created from your Bluesky settings) are defined. These details are essential for generating a session token.
   
   Note: This workflow assumes those credentials are hard-coded, but you can enhance security by storing them in n8n’s built-in credential management system.
   
   Step 3: Creating a Bluesky Session
   
   With credentials in place, an HTTP Request node (“Create Bluesky Session”) authenticates you via Bluesky’s com.atproto.server.createSession endpoint. A successful call returns, among other things, an accessJwt (a session token) and a DID (decentralized identifier), both vital for the steps that follow.
   
   Step 4: Writing the Caption
   
   You can compose the textual portion of your post in the “Set Caption” node, allowing up to 300 characters. This text will be embedded alongside the image content using the Bluesky embed object schema.
   
   Step 5: Setting and Fetching Image URLs
   
   In the “Set Images” node, you define an array of image URLs—up to four at a time, which is the current maximum set by Bluesky's API. These images must be under 1MB and available via public URLs.
   
   The “Split Out” node processes each image individually, ensuring every URL is handled in sequence. This modular structure prepares each image for upload.
   
   Step 6: Downloading and Uploading Images
   
   Using the “Download Images” node, n8n fetches the binary data of each image. These get passed to the “Post Image to Bluesky” node, which utilizes Bluesky's com.atproto.repo.uploadBlob endpoint to host individual image files. They are not directly embedded into posts but uploaded as blobs first—a Bluesky-specific requirement.
   
   Step 7: Structuring Image Embeds
   
   Once all uploads are complete, a “Code” node reformats the returned blob data into an array of image objects suitable for embedding. Captions for images are set to a placeholder (“-”), but you can easily modify this part of the code for more descriptive alt text if needed.
   
   The “Aggregate” node collects all these image entries into a single payload for use in the final post.
   
   Step 8: Posting to Bluesky
   
   The last critical step—“Post to Bluesky”—sends a properly formatted request to create a record via the com.atproto.repo.createRecord endpoint. The payload includes:
   - Your DID (as the user repository),
   - The post text (from the “Set Caption” node),
   - A timestamp (generated with $now),
   - And the array of image blobs (as an embed object).
   
   Result: Your post goes live on your Bluesky feed, complete with the images and custom caption.
   
   Extra Notes
   
   🔒 Security:
   While this walkthrough includes hardcoded credentials for simplicity, you should store sensitive data like usernames and passwords more securely. n8n’s credential management is a perfect way to do that.
   
   💡 Customization:
   You can add features such as dynamic captioning, scheduling (using Cron or Webhook triggers), or automatically pulling image URLs from another source like an RSS feed or an Airtable base for more advanced automation.
   
   📂 API References:
   Each major interaction with Bluesky is made through their AT Protocol interface, detailed in the Bluesky developer documentation. Primary endpoints used:
   - Create session: com.atproto.server.createSession
   - Upload image blob: com.atproto.repo.uploadBlob
   - Create a post: com.atproto.repo.createRecord
   
   Conclusion
   
   This end-to-end n8n workflow for posting image-enriched content to Bluesky offers a powerful, flexible approach to automation. From uploading images to constructing a post that adheres to Bluesky's API specs, it handles each step seamlessly. Whether you're an automation enthusiast or a social media manager, this setup provides a reusable, scalable solution for consistent and engaging Bluesky content.
   
   Ready to automate your next Bluesky post? With n8n, it’s just a few clicks away.

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.
