Generate Your First Image

APITemplate.io's image generation lets you create banners, social media graphics, and personalized visuals from reusable templates. No HTML or CSS knowledge required.

Step 1: Create an image template​

  1. Go to Manage Templates and click New Image Template
  2. Choose a preset (like an Instagram post, Facebook banner, or Pinterest pin) or start from a blank canvas
  3. Click Launch Image Editor on your new template

Step 2: Design your template​

The image editor is a visual drag-and-drop canvas where you can:

  • Add text elements — headlines, subtitles, body text
  • Add images — backgrounds, logos, photos
  • Add shapes — rectangles, circles, lines
  • Add dynamic components — QR codes, barcodes
  • Resize and position elements with precision controls

Give each dynamic element a meaningful name (like headline, subtitle, logo). These names map to JSON properties when generating images via the API.

Step 3: Test with the API Console​

  1. Click the Preview/API Console tab in the editor
  2. Click Generate JSON Data to populate the sample JSON
  3. Modify the JSON to change text, images, or other properties
  4. Click Quick Preview (Free) to see the result

Step 4: Generate via the API​

Once your template is ready, you can generate images by sending a POST request to the create-image endpoint. Replace YOUR_TEMPLATE_ID with the template ID from your dashboard and YOUR_API_KEY with your API key.

The overrides array lets you swap out any named element in your template — pass the element's name and the new text, src (for images), or other properties.

curl -X POST "https://rest.apitemplate.io/v2/create-image?template_id=YOUR_TEMPLATE_ID" \
  -H "X-API-KEY: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "overrides": [
      {
        "name": "headline",
        "text": "Welcome to APITemplate.io!"
      },
      {
        "name": "subtitle",
        "text": "Generate images at scale"
      }
    ]
  }'

The response includes a download_url for the generated image.

For the full list of parameters, output options, and error codes, see the REST API Reference (v2).
