Why Use an API for T-Shirt Mockups?

Manual mockup creation doesn't scale. Opening Photoshop, placing designs, exporting files - it takes 5-10 minutes per mockup. With hundreds of designs and multiple color variants, that's weeks of work. SudoMock's REST API generates production-ready t-shirt mockups in milliseconds via a simple HTTP POST request.

Perfect For

  • ✓Print-on-demand sellers with large design catalogs
  • ✓E-commerce platforms generating product images automatically
  • ✓Design tools offering mockup preview features
  • ✓Marketing teams creating campaign visuals at scale

Setting Up T-Shirt Templates

Start by uploading your t-shirt PSD templates. Each template should have Smart Object layers for design placement. SudoMock supports unlimited Smart Objects per template - front print, back print, sleeve prints, all in one PSD.

Upload T-Shirt Template
1# Upload t-shirt template
2curl -X POST "https://api.sudomock.com/api/v1/psd/upload" \
3  -H "Content-Type: application/json" \
4  -H "X-API-KEY: YOUR_API_KEY" \
5  -d '{
6    "psd_file_url": "https://your-storage.com/tshirt-front-black.psd",
7    "psd_name": "Black T-Shirt Front"
8  }'

10# Response includes mockup_uuid and smart_object UUIDs
11{
12  "success": true,
13  "data": {
14    "uuid": "tshirt-black-front-uuid",
15    "name": "Black T-Shirt Front",
16    "smart_objects": [
17      {
18        "uuid": "design-area-uuid",
19        "name": "Design Placement",
20        "size": { "width": 2400, "height": 3200 }
21      }
22    ]
23  }
24}

Generating T-Shirt Mockups

Once your template is uploaded, generate mockups by calling the render endpoint with your design URL. The API returns a CDN-hosted image URL.

Batch Processing for Variants

For POD businesses with many color variants, batch processing is essential. SudoMock supports up to 25 parallel requests (Scale plan), letting you generate an entire product line in seconds.

Parallel Variant Generation
1// Generate all t-shirt variants in parallel
2const TSHIRT_COLORS = ['black', 'white', 'navy', 'red', 'gray'];
3const TSHIRT_VIEWS = ['front', 'back', 'lifestyle'];
4

5async function generateAllVariants(designUrl) {
6  const renderPromises = [];
7  
8  for (const color of TSHIRT_COLORS) {
9    for (const view of TSHIRT_VIEWS) {
10      renderPromises.push(
11        renderMockup({
12          templateId: `tshirt-${color}-${view}`,
13          designUrl,
14          outputName: `${color}_${view}.webp`
15        })
16      );
17    }
18  }
19  
20  // 15 mockups generated in parallel
21  // Total time: ~2 seconds (not 15 seconds!)
22  const results = await Promise.all(renderPromises);
23  
24  return results;
25}

Pro Tip: Use WebP Format

WebP images are 30% smaller than PNG with equivalent quality. Faster page loads, lower CDN costs, and better SEO scores for your product pages.

Automation Workflows

Connect SudoMock to your design pipeline with n8n, Zapier, or Make. When a new design is uploaded to your storage, automatically generate all t-shirt mockups and push them to your e-commerce platform.
