What We're Building

This pipeline automatically generates product mockups whenever you upload a new design. Here's the flow:

Trigger — New file uploaded to Google Drive/Dropbox
Generate — SudoMock creates mockups for all product types
Organize — Save mockups to your storage with proper naming
Publish — Create draft listings on Etsy/Shopify (optional)

Prerequisites

  • n8n account (cloud or self-hosted)
  • SudoMock API key (get free credits)
  • Cloud storage account (Google Drive, Dropbox, or S3)
  • PSD templates uploaded to SudoMock

Step-by-Step Setup

1

Create the Trigger

In n8n, create a new workflow and add a Google Drive Trigger node (or your preferred storage). Configure it to watch your designs folder.

Trigger Configurationjson
{
  "resource": "file",
  "event": "fileCreated",
  "watchFolder": "POD Designs",
  "fileTypes": ["image/png", "image/jpeg"]
}
2

Add HTTP Request Node

Add an HTTP Request node to call SudoMock's render API. This generates your mockups.

SudoMock API Calljson
{
  "method": "POST",
  "url": "https://api.sudomock.com/api/v1/renders",
  "headers": {
    "X-API-KEY": "{{ $credentials.sudomockApiKey }}",
    "Content-Type": "application/json"
  },
  "body": {
    "mockup_uuid": "your-tshirt-template-uuid",
    "smart_objects": [{
      "uuid": "your-smart-object-uuid",
      "asset": {
        "url": "{{ $json.webContentLink }}"
      }
    }],
    "export_options": {
      "image_format": "webp",
      "image_size": 2000,
      "quality": 95
    }
  }
}

Multiple Products

Use a Split In Batches node to generate mockups for multiple product types (t-shirt, hoodie, mug) in parallel. Each product type gets its own HTTP Request node.
3

Save Results

Add another Google Drive node to save the rendered mockups. Use expressions to create organized folder structures.

Save Configurationjson
{
  "operation": "upload",
  "folder": "Mockups/{{ $json.design_name }}",
  "fileName": "{{ $json.product_type }}_{{ $json.design_name }}.webp",
  "binaryData": false,
  "fileUrl": "{{ $json.data.print_files[0].export_path }}"
}
4

Optional: Create Listings

Connect to Etsy or Shopify APIs to automatically create draft listings with your new mockups.

27      "position": [650, 300],
28      "parameters": {
29        "operation": "upload"
30      }
31    }
32  ],
33  "connections": {
34    "Google Drive Trigger": {
35      "main": [[{"node": "Generate T-Shirt Mockup"}]]
36    },
37    "Generate T-Shirt Mockup": {
38      "main": [[{"node": "Save to Drive"}]]
39    }
40  }
41}

Advanced Tips

Error handling — Add Error Trigger nodes to catch API failures and send alerts
Rate limiting — Use Wait nodes between API calls if hitting rate limits
Parallel processing — Split batches for faster processing of multiple designs
Logging — Add Airtable or Google Sheets nodes to track processed designs

Result

Once set up, every design you drop into your folder automatically becomes a complete set of product mockups — ready for your store. No manual work required.
