# Merchant settings

Everything about your store lives under **Edit** for your merchant: its name and currency, the domains allowed to use it, a ready-made link for your newsletter, and the status of purchase tracking.

## Store details

Update your **merchant name** and **default reward currency** any time. Your domain is shown here too. Click **Edit**, make your change, then **Save**.
**Note:** The currency here is the default for new campaigns. You can still pick a different currency on any individual campaign.

## Allowed domains

If your store runs on more than one address, add the extras under **Allowed domains** so Frak recognizes them all. A common case is a Shopify store that also uses its `myshopify.com` address.

Type the domain (like `mystore.myshopify.com`), click **Add domain**, and save. Remove one any time with **Remove**.
**Tip:** Your main registered domain already works. You only need this for additional domains or subdomains.

## Newsletter sharing link

Want to invite your existing customers to share? Copy your **newsletter sharing link** and drop it into any marketing email. When a customer clicks it, your storefront opens with the Frak sharing window ready, pre-filled with your current rewards, so they can share and earn in one tap.

## Purchase tracking

The **Purchase tracker** shows whether Frak is receiving orders from your store, which is what lets campaigns reward real sales. You'll see the connection status, the platform in use, and when the last purchase came in.

For most stores this is set up automatically by your platform app:

[Shopify](/guides/shopify/)
[WordPress / WooCommerce](/guides/platforms/wordpress/details/)
[PrestaShop](/guides/platforms/prestashop/details/)
**Custom store?:** If you built your store yourself, you can register the webhook manually here. The full setup is in the [purchase webhook reference](/developers/api/webhook/).
