Built for teams that generate mockups at scale

Whether you are automating a POD marketplace or adding mockups to a SaaS product, the MockupKit API handles template lookup, smart object placement, and render delivery.

Print-on-demand platforms

Generate mockups programmatically for every SKU when a seller uploads a design. Batch render across apparel, mugs, posters, and home goods without manual Photoshop work.

E-commerce catalogue automation

Use the product mockup API to create listing images for Shopify, Etsy, and Amazon at scale. Swap artwork per variant and keep product shots consistent across your store.

Bulk mockup generation

Render one design on dozens of templates in a single API call with template_ids[] or an entire collection with collection_id. Built for bulk mockup generator API workflows.

Custom design tools

Build custom product configurators with template metadata and colour fill overrides, then call POST /v1/render for the final high-resolution output.

Integration examples

Authenticate with an API key, pick a template or collection, pass a publicly accessible artwork URL, and receive a render URL in the response.

Example 1

Discover templates with filters

Load filter taxonomy once, then fetch a lightweight catalogue with ?fields=summary.

GET /v1/filter-config → GET /v1/templates

# 1. Filter options for your UI
curl -s https://api.mockupkit.app/v1/filter-config \
  -H "Authorization: Bearer YOUR_API_KEY"

# 2. Filtered catalogue (no smart_objects payload)
curl -s "https://api.mockupkit.app/v1/templates?fields=summary&product_type=apparel" \
  -H "Authorization: Bearer YOUR_API_KEY"

Example 2

Single product mockup

Render one template with artwork URL. Ideal for on-demand listing images.

POST /v1/render

curl -X POST https://api.mockupkit.app/v1/render \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "template_id": "01773337-3a38-44d5-9486-9756b590a1de",
    "artwork_url": "https://your-cdn.com/design.png",
    "output_format": "jpg"
  }'

Example 3

Render with colour overrides

Override PSD solid fill layers by layer_name when calling POST /v1/render.

POST /v1/render

curl -X POST https://api.mockupkit.app/v1/render \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "template_id": "b56e03e2-05e4-4847-bec9-941680dcd444",
    "artwork_url": "https://your-cdn.com/design.png",
    "output_format": "jpg",
    "color_fills": {
      "Sleeve Color": "#2563EB",
      "Collar Color": "#111827"
    }
  }'

Example 4

Bulk mockup generator API

Generate mockups programmatically across multiple templates in one request.

POST /v1/render

curl -X POST https://api.mockupkit.app/v1/render \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "template_ids": [
      "template-id-1",
      "template-id-2",
      "template-id-3"
    ],
    "artwork_url": "https://your-cdn.com/design.png",
    "output_format": "jpg"
  }'

Example 5

Colour fill API

Garment and background colours from the PSD

Templates with Photoshop solid colour fill layers expose color_fills on template endpoints. Use the defaults to populate colour pickers in your UI, then pass overrides to POST /v1/render.

How PSD layers become API metadata

Fetch colour metadata

GET /v1/templates/:templateId returns color_fills[] with default hex values and layer names from the PSD.

Render with overrides

POST layer_name → #RRGGBB overrides to /v1/render. Photoshop applies the fills server-side. No mask URLs needed in the request.

Fetch colour metadata

GET /v1/templates/:templateId

curl -s https://api.mockupkit.app/v1/templates/b56e03e2-05e4-4847-bec9-941680dcd444 \
  -H "Authorization: Bearer YOUR_API_KEY" | jq '.template.color_fills'

[
  {
    "layer_name": "Color",
    "layer_path": "Group/Color",
    "color": { "r": 239, "g": 62, "b": 63, "hex": "#EF3E3F" },
    "fill_mask_url": "https://.../fill-masks/...-color.png",
    "masks": [
      { "id": "Color-layer-raster", "kind": "layer_raster", "url": "https://..." }
    ],
    "blend_mode": "normal",
    "parent_group": { "name": "Group", "blend_mode": "normal" }
  },
  {
    "layer_name": "Sleeve Color",
    "color": { "r": 239, "g": 62, "b": 63, "hex": "#EF3E3F" },
    "fill_mask_url": "https://.../sleeve-colour.png"
  }
]

Render with colour overrides

POST /v1/render

curl -X POST https://api.mockupkit.app/v1/render \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "template_id": "b56e03e2-05e4-4847-bec9-941680dcd444",
    "artwork_url": "https://your-cdn.com/design.png",
    "output_format": "jpg",
    "color_fills": {
      "Sleeve Color": "#2563EB",
      "Collar Color": "#111827"
    }
  }'

Keys must match layer_name from the template (case-insensitive). Send hex only. Do not include fill_mask_url.
