Going live

Build and test with test keys. When you are ready for real shoppers, activate live mode for your store in Studio → Activate live mode, then swap pk_test_… / sk_test_… for live keys.

The live activation checklist

Live keys can be created, and live origins served, only when every item is done. Studio shows the checklist with a link for each item.

#	Item	What it means
1	Verified domain	At least one verified domain on your organization, covering every live origin
2	Terms	The owner accepted the current Terms of Service and Data Processing Agreement
3	Billing details	Legal name, country and billing email (and a VAT ID if you are an EU business). Done automatically when you are billed through Shopify or have a contract with us
4	Payment method	Needed only on a paid plan. The free Starter plan does not need a card: it has a hard cap of 2,500 fit checks per month
5	Organization active	Your organization is not suspended

Then press Activate live mode (owners and admins with the live.activate permission; you are asked to sign in again). It is recorded in your audit log.

Verify your domain

In Studio → Settings → Domains, add your domain and prove you control it with one of:

Method	How
DNS TXT record (default)	Add _tryyoursize.<your domain> with the value tys-verify=<token>
Meta tag	Put <meta name="tryyoursize-verification" content="<token>"> on your home page (https://<your domain>/). For hosted shops without DNS access
Shopify	Automatic for your *.myshopify.com host and primary domain when you install the Shopify app

• A verified apex domain (brand.com) covers https://brand.com, https://www.brand.com and https://*.brand.com.
• A hostname can be verified by only one organization.
• Domains are checked again every week. After 3 failed checks in a row a domain lapses; its live origins keep working for 14 more days, then stop. Keep the TXT record or meta tag in place.

Billing

• A fit check is one shopper seeing a size for one product, in live mode. The same shopper and product count once per 30 days. A changed body counts again.
• Test mode is never metered. Shoppers in an A/B holdout are never metered either: they see no element.
• A page view never starts a simulation. Server-side recommendations count like browser ones: a delivered size is a fit check.
• Starter is free with a hard cap of 2,500 fit checks per month and 100 published styles. Above the cap, the size guide hides and size answers are unavailable until the next period; shoppers never see an error. Paid plans can set a budget cap.
• Plans and prices: tryyoursize.com/#pricing. Shopify stores can be billed through Shopify.

Usage is in Studio → Settings → Usage; plan and invoices in Settings → Billing.

Go-live checklist for developers

• Replace test keys with live keys (publishable on the page, secret on the server). Keep test keys for your staging site.
• Register your production origins for live mode.
• Publish every garment you want live shoppers to see (live answers published versions only).
• Map every shop size in each product’s size map (publishing needs it).
• Add a live webhook endpoint if you use webhooks; endpoints are per mode.
• Check your Content Security Policy allows https://js.tryyoursize.com (scripts) and https://embed.tryyoursize.com (frames).
