System and global settings
Set these before you rely on the catalog or on orders: store identity, payments, mail, currency and languages, then tax.
Store identity
Open System → Site Settings for the public name, tagline, and Site URL.
The Site URL is the address written into the sitemap, canonical and social tags, and links inside system emails. It does not turn the store on or off. While a custom domain is still propagating, the store stays reachable at the Amplify address. Set the Site URL to the public address you want customers and search engines to see. If it is left empty, generated links fall back to a built-in default, so email links will be wrong until you save the real URL.
System → Email Settings → Sender is the from-name and from-address on order mail and other customer messages.
Payments
Open System → Payment Settings. A channel that is off stays hidden at checkout. Save at the bottom of the page after you edit a channel.
| Channel | What to enter |
|---|---|
| Stripe | Turn it on, paste test keys first (pk_test_ / sk_test_), then switch to Live and paste live keys. Checkout embeds the card form. Copy the webhook URL into Stripe for checkout.session.completed, and paste the webhook signing secret. |
| PayPal | Turn it on, paste Sandbox Client ID and Secret, then switch to Live. Checkout shows PayPal buttons. Copy the webhook URL into PayPal for CHECKOUT.ORDER.APPROVED and PAYMENT.CAPTURE.COMPLETED, and paste the Webhook ID. |
| Mock | A test channel. One click marks the order paid. Turn it off before the store is live. |
Mail
Transactional mail and the shop mailbox use a normal mail host. You still create that mailbox with your email provider. After it is connected, you read and write it from the admin.
| Direction | Where | What it does |
|---|---|---|
| Outbound | Email Settings → SMTP | Sends sign-up, password reset, order updates, and mail you compose. Common ports are 465 (SSL) and 587 (STARTTLS). Use the mailbox SMTP or app password. |
| Inbound | Email Settings → IMAP | Polls the same mailbox into Support → Email Inbox. It uses the same username and password as SMTP. |
| Order mail | Email Settings → Order emails | Turns status emails on or off, and chooses which statuses send one. |
Support → Compose Email, Email Inbox, and Email Outbox are the mailbox inside the admin. After SMTP is saved, send yourself a test from Compose Email before you rely on it.
Currency and languages
One currency applies to list prices, the cart, checkout, and orders. Open System → Currency & tax and choose USD, EUR, or HKD. Those are the only store currencies. Stripe or PayPal must support the one you pick.
Guest checkout sits on the same screen. It is off until you turn it on. When it is on, a shopper can order with an email address and a link in the confirmation mail, without an account.
Languages are separate. This kit installs seven: English (en), Traditional Chinese (hk, content key zh-TW), Japanese (jp / ja), Korean (kr / ko), German (de), French (fr), and Spanish (es).
Open System → Storefront Languages to choose which of those are public on the storefront, the language switcher, and the sitemap. English stays on. Until you save a custom list, the public set is English, Traditional Chinese, Japanese, and Korean. German, French, and Spanish stay off until you enable them. The translations themselves stay in the codebase. This screen only shows or hides a language.
Tax
Tax is off until you enable Calculate tax at checkout on Currency & tax.
| Tax | How prices work |
|---|---|
| Off | Enter tax-inclusive prices on products. Say so in your shop terms if you need to. |
| On | Product prices are treated as tax-exclusive. The percentage is added at checkout, on the merchandise subtotal after order discounts. Shipping is not included in that base. The rate is a number from 0 to 100. |
