GarmCheck end-to-end setup

Sign up at garmcheck.com/signup using your work email. You'll land on the Dashboard once verified. Shopify merchants installing from the App Store are signed in automatically inside the Shopify admin iframe — no separate login needed.

Go to Installation and choose one of two channels — both share the same backend, usage and analytics.

In your Shopify admin:

1. Open Online Store → Themes → Customize.
2. Switch to the Product template in the top selector.
3. Under the main product section, click Add block.
4. Pick GarmCheck → Try-On Button.
5. Tick Enable try-on and drag the block to where you want the button (we recommend just below the variant picker).
6. Click Save.

The button only appears on the live PDP when both the theme block and the per-product toggle (next step) are on.

In Products, flip the Try-On switch for each product you want to support. You can enable in bulk by toggling rows quickly — the dashboard shows a live count at the top.

On first enable, GarmCheck pulls every image for that product from your Shopify catalogue and auto-picks the best garment reference image (see next step).

We score every Shopify image for the product and pick the best reference for the try-on engine. The logic, in order:

• Pose detection — runs on-device pose detection locally in the dashboard browser. Images with a visible human body are preferred.
• Front-facing model shot — chosen when shoulder landmarks are roughly horizontal and centred.
• Keyword fallback — alt text or filename containing tryon, front, model, or hero wins ties.
• Final fallback — the product's primary image.

To force a specific image without overriding manually, just rename the file or alt text to include tryon in Shopify and re-toggle the product.

In Products, click Configure on any product, then Change next to the selected image. You'll see a grid of every Shopify image for that product — click one to set it as the try-on reference. Save to persist.

Per-product sizing improves recommendation accuracy and unlocks the fit advisory inside the try-on flow.

• Size Charts — upload or paste a shared chart (e.g. brand-wide women's tops) and assign it to many products at once.
• In Products → Configure, set the Fit type (fitted, relaxed, oversized, structured, stretch) and Primary measurement (chest, waist, hips). Defaults work for most catalogues.
• For full per-product charts with all 8 measurements, open the per-product size chart editor from the Configure drawer.

In Integrations, connect Klaviyo to stream try-on, recommendation and add-to-cart events into your customer profiles for retargeting and fit-based segmentation. Standard webhooks and a public REST endpoint are also available — ask support if you need a custom destination.

Open one of the enabled PDPs in an incognito window and verify:

• The Try It On button appears under the variant picker.
• Clicking it opens the GarmCheck modal with the correct garment image.
• Uploading a photo or using a sample model returns a try-on result in 8–15s.
• Size suggestion appears if a size chart is configured.

Not seeing the button? 99% of the time it's one of: theme block not saved, product toggle off, or you're previewing the wrong template. Check both toggles in Products and your theme customizer.

New accounts include a free trial allowance. When you're ready to go live, pick a plan in Billing. Shopify merchants are billed through Shopify's managed billing — the charge appears on your monthly Shopify invoice.
