How do I automate product image generation for Shopify?

Use a mockup API to generate images, then Shopify's Admin API to upload them to products. Automation platforms like n8n or Zapier can orchestrate the workflow - triggering on new products and automatically attaching generated mockups.

Can I update existing Shopify product images via API?

Yes, Shopify's Admin API supports creating, updating, and deleting product images. You can replace existing images with new mockups or add additional variants - all programmatically without accessing the Shopify admin dashboard.

What image specifications does Shopify require?

Shopify accepts JPEG, PNG, GIF, and WebP formats up to 20MB. Recommended size is 2048x2048 pixels square for best quality. Configure your mockup API output to match these specs for optimal display.

How do I generate mockups for all Shopify product variants?

Fetch all variants via Shopify API, loop through each, call the mockup API with variant-specific designs (colors, sizes), then upload images back to corresponding variants. This can be fully automated with workflow tools.

Can I use Shopify's CDN for mockup storage?

Yes, when you upload images via Shopify's API, they're automatically stored on Shopify's CDN. This provides fast, reliable delivery without managing your own image hosting infrastructure.
