Frequently Asked Questions
Everything about automating image generation with a REST API.
What is an image automation API?
An image automation API lets you generate images programmatically by sending data to a REST endpoint. You design a template once with dynamic layers for text, images, and colors, then pass new values through the API to render each variation. There is no manual design work, so you can produce thousands of on-brand, personalized images in seconds.
What is the difference between an image automation API and AI image generation?
An image automation API renders pixel-perfect, brand-consistent images from your own templates and structured data. AI image generation tools like DALL-E or Midjourney create entirely new images from text prompts, so the output is unpredictable and hard to keep on-brand. When you need consistent, repeatable visuals like certificates, product cards, social posts, and banners, image automation is the right choice.
How do I generate images from templates via API?
It takes three steps. First, design your template in the visual editor and copy its template ID. Second, decide which layers should be dynamic, such as a headline, price, or product photo. Third, send a POST request to the render endpoint with your API key, the template ID, and a JSON object of layer changes. The API returns a hosted image URL in seconds, ready to use anywhere.
How many images can I generate per month?
You can start free with 50 render credits, no credit card required. Paid plans scale from 1,000 renders per month up to 25,000, and Enterprise covers higher volumes. One credit equals one image, one PDF page, or one second of video, so the same plan works across every format.
Is there a free image automation API?
Yes. You can start free with 50 render credits and no credit card. The free tier includes full access to the visual editor and the REST API, so you can validate a real workflow before paying anything.
What formats can the API output?
The same template can render as PNG, JPG, WebP, a multi-page PDF, or an MP4 video. You control quality, dimensions, and resolution per request, so one design serves every channel.
Can I generate PDFs with an image automation API?
Yes. PDF output is supported alongside images, which is ideal for certificates, invoices, and event tickets. You can render multi-page PDFs from a single template, with each page populated by different data.
Can I generate videos with an image automation API?
Yes. The API can render MP4 video from a template, so you can produce dynamic video variations the same way you generate images. Video is billed by duration: one credit equals one second of video.
How do I integrate an image automation API with Make.com?
Image Automation API works natively with Make.com through an HTTP module. Create a scenario, add an HTTP request module, point it to the render endpoint, and pass your template ID with the dynamic layer data as JSON. Make can trigger renders from Google Sheets, Shopify, forms, or any connected app, giving you a fully automated pipeline with no code.
How do I integrate an image automation API with Zapier?
Use the Webhooks by Zapier action. Set up a Zap with your trigger, such as a new row in Google Sheets or a new Shopify product, then add a webhook action that POSTs to the render endpoint with your template ID and layer changes. The rendered image URL is returned in the response for downstream steps like email, Slack, or storage.
How do I integrate an image automation API with n8n?
n8n supports Image Automation API through its HTTP Request node. Add the node, configure a POST request to the render endpoint, include your API key in the headers, and the template data in the body. n8n is self-hostable and open source, which suits teams that want full control over their automation infrastructure.
Which image automation APIs work with Shopify?
Image Automation API integrates with Shopify through webhooks, Zapier, or Make. When a product is created or updated, you can trigger a render that generates a product card, social image, or promotional banner from the product data, keeping your visual assets in sync with your catalog automatically.
Can I import designs from Canva?
Yes. You can import designs you already built in Canva and turn them into automated, API-ready templates. There is no need to rebuild layouts from scratch, so your existing brand work carries straight over.
Does it work with no-code tools and AI assistants?
Yes. On the no-code side it connects to Zapier, Make, n8n, Airtable, and Bubble. For developers there is a clean REST API with libraries for Python, Node, Java, PHP, and Ruby. It also exposes an MCP server, so you can drive image generation from Claude, Cursor, or ChatGPT.
What is template-based image generation?
Template-based image generation means you design a reusable layout with dynamic layers, then generate variations by swapping those layers via API. Unlike AI generation, the output is deterministic and brand-consistent every time, with exact control over position, font, color, and size. That makes it ideal for production use cases like certificates, marketing materials, and product images.
