How to Use Placid to Generate Social Images Automatically
Creating on-brand social media visuals for every blog post, product update, or event announcement takes serious time. If you're publishing content regularly, manually designing each image in Canva or Photoshop simply doesn't scale. That's exactly where placid comes in — a powerful image generation API built for automation.
In this guide, you'll learn how to use placid together with n8n to automatically generate beautiful, consistent social media images every time you publish new content.
What Is Placid?
placid is a design automation tool that lets you create reusable image templates and populate them dynamically with data — text, images, colors, and more. Instead of opening a design tool every time you need a new visual, placid generates pixel-perfect images via API in seconds.
It's trusted by marketers, developers, and content creators who need to produce large volumes of visuals without sacrificing brand consistency.
What Is n8n?
n8n is an open-source workflow automation platform. Think of it like Zapier or Make, but far more flexible and developer-friendly. You can self-host n8n or use their cloud version to connect hundreds of apps and services together without writing complex code.
When you combine n8n with placid, you unlock a genuinely powerful content automation pipeline.
Why Automate Social Image Creation?
- Save hours every week — no more manual design work for every post
- Stay consistent — every image follows your brand template automatically
- Scale effortlessly — publish 10x the content without 10x the effort
- Reduce human error — no more typos or wrong colors in published visuals
Step 1: Create Your Template in Placid
Log in to your placid account and navigate to the Templates section. Click Create Template and choose your canvas size — for example, 1200×630px for Open Graph images or 1080×1080px for Instagram.
Use the drag-and-drop editor to design your template. Add the following dynamic layers:
- Title layer — a text field that will receive your post title
- Image layer — a background or featured image placeholder
- Tag or category layer — optional label for content type
- Logo layer — your static brand logo
Once your template looks great, save it. placid will give you a Template ID — you'll need this later.
Step 2: Get Your Placid API Key
In your placid dashboard, go to Settings → API and copy your API key. This is how n8n will authenticate with the placid service when requesting image generation.
Step 3: Build the Workflow in n8n
Open your n8n instance and create a new workflow. Here's the node structure you'll build:
Trigger Node
Use a Webhook node or a scheduled Cron trigger. If you're using WordPress, you can trigger the n8n workflow via a webhook every time a new post is published.
HTTP Request Node — Call Placid API
Add an HTTP Request node and configure it as follows:
- Method: POST
- URL:
https://api.placid.app/api/rest/images - Authentication: Bearer Token (paste your placid API key)
- Body: JSON with your template ID and dynamic layer values
Here's an example JSON body:
{
"template_uuid": "YOUR_TEMPLATE_ID",
"layers": {
"title": { "text": "{{ $json.post_title }}" },
"image": { "image": "{{ $json.featured_image_url }}" }
}
}placid will return a URL to your generated image. The n8n workflow then captures that URL for the next step.
Optional: Upload to Google Drive or S3
Add a Google Drive or AWS S3 node to automatically store the generated image. n8n makes this connection seamless with built-in integrations.
Optional: Post to Social Media
Use a Buffer, Twitter/X, or LinkedIn node in n8n to automatically schedule the post with your freshly generated image attached.
Step 4: Test and Activate
Run a test execution in n8n with sample data. Check that placid returns a valid image URL and that your layers are populated correctly. Inspect the generated image visually — confirm that the title fits, the image renders, and the branding is consistent.
Once everything looks perfect, activate the n8n workflow. From now on, every new content piece will trigger the automation and produce a ready-to-use social image in seconds.
Pro Tips for Better Results
- Create multiple templates in placid — one for each platform or content type
- Use conditional logic in n8n to pick the right template based on post category
- Add error handling in n8n so failed image generations trigger a Slack alert
- Version your templates in placid before making design changes
