How do you generate bulk images from a Canva template?

Generating bulk images from a Canva template means creating many personalized variants of one design, each with different text, images, or colors. Here are the main approaches:

Option 1: Canva Bulk Create (built-in, manual)

Canva's native Bulk Create feature lets you upload a CSV, map columns to design elements, and generate variants inside the editor. However:

• It's entirely manual (no API, no automation triggers)
• You can only swap text and images; no color or font changes
• Users report a limit of ~100 variants per batch
• You must manually download the results

Option 2: API-based automation (recommended for scale)

Import your Canva design into a tool like Layerre, then generate via API:

1. Share your Canva design and paste the link into Layerre
2. Layerre imports the design and identifies all customizable layers
3. Call the API for each variant you need:

POST https://api.layerre.com/v1/template/YOUR_TEMPLATE_UUID/variant
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

{
  "overrides": [
    {
      "layer_id": "NAME_TEXT_LAYER_UUID",
      "properties": { "text": "Alice Johnson" }
    },
    {
      "layer_id": "ROLE_TEXT_LAYER_UUID",
      "properties": { "text": "Top Contributor" }
    },
    {
      "layer_id": "BADGE_IMAGE_LAYER_UUID",
      "properties": { "img_url": "https://cdn.example.com/gold.png" }
    }
  ],
  "export_type": "png"
}

4. Read the signed image URL from the JSON response (url)

Option 3: No-code bulk generation

Connect Layerre to Make, Zapier, or n8n. Set up a flow that reads rows from Google Sheets or Airtable and triggers a render for each row. The generated images can be saved to Google Drive, emailed, or posted directly.

When to use each approach:

For anything beyond occasional small batches, API-based automation saves significant time and eliminates manual work.
