How to Add AI Virtual Try-On to Your Shopify Store (Step by Step)

If you run a Shopify fashion store, adding AI virtual try-on is one of the highest-leverage upgrades you can make to your product pages — and it's far less work than most merchants expect. This guide walks through the whole process with FashClick, from connecting your store to putting a "Try it on" button in front of shoppers.

Before you start

You'll get the best results if you have:

• A Shopify store with products that have clear, front-facing images.
• Products categorised sensibly (tops, bottoms, dresses, outerwear) — this helps the try-on place garments correctly.
• A FashClick account. You can start on the free tier; talk to us if you want an enterprise pilot.

You do not need new photography, 3D models, or a developer on standby. FashClick works from the catalogue images you already have. Curious how that's possible? See What Is AI Virtual Try-On?

Step 1 — Connect your Shopify store

From the FashClick dashboard, choose Connect store and authorise the Shopify connection. This grants read access to your product catalogue so FashClick can pull in product images and details. The connection is scoped and revocable from Shopify at any time.

Step 2 — Sync your catalogue

Once connected, sync your products. FashClick imports each product's images and category so they're ready to be used as garment images in a try-on. For best results:

• Use the cleanest front-facing image as the primary product photo.
• Make sure the product type maps to the right garment category (upper body, lower body, full outfit, footwear).
• Remove heavily styled or group shots from the primary slot — a single clear garment renders best.

Step 3 — Enable the "Try it on" experience

Turn on try-on for the products or collections you want. On the storefront, shoppers get a Try it on button on the product page. When they tap it they can upload a photo of themselves (or pick from saved photos), and FashClick renders the garment on them in seconds.

The rendering runs asynchronously, so it never blocks your page load — your Shopify theme performs exactly as before, and the try-on opens on demand.

Step 4 — Customise the placement (optional)

For merchants who want full control over look and placement, FashClick exposes a complete developer API. With it you can:

• Trigger try-on from a custom button anywhere in your theme.
• Render multi-garment outfits — show a top, trousers and jacket together to lift average order value.
• Run batch jobs to pre-generate on-model imagery for an entire collection.
• Receive webhooks when results are ready, so you can cache and display them instantly.

The API uses a simple X-Api-Key header and returns a request you can poll or subscribe to — full examples in cURL, JavaScript, Python and C# live in the docs.

Step 5 — Measure the impact

Don't just ship it — prove it works. Track:

• Conversion rate for try-on users vs a control group — see our A/B testing guide.
• Return rate, which try-on typically lowers — see how try-on cuts returns.
• Average order value, especially if you enable multi-garment outfits.

Troubleshooting tips

• Results look off? Swap the primary image for a cleaner, front-facing shot of the garment alone.
• Wrong placement? Check that the product's category maps to the correct garment type.
• Shopper photos vary wildly? Add light in-app guidance: a well-lit, front-facing, full-body photo gives the best try-on.

The bottom line

Adding AI virtual try-on to Shopify is a connect-sync-enable process that most merchants can complete in an afternoon — no new photoshoot, no 3D modelling. Start simple with the product-page button, measure the lift, then graduate to custom API placements as you scale. Ready to begin? Talk to our team or dive into the developer docs.
