# Going live

> Verify your domain, complete the live activation checklist, and understand billing before you switch to live keys.

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](https://docs.tryyoursize.com/quickstarts/shopify.md) |

- 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](https://docs.tryyoursize.com/guides/ab-holdout.md) 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](https://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](https://docs.tryyoursize.com/guides/webhooks.md) 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).
