BASE

Start with merchant-fixable rows. Platform residual rarely yields to a theme edit — hand it to your agency or the platform.

Merchant-fixable

IDWherePermissionNext step
JP-FORM-NOLABELHTML編集 (HTML Editor) App → your custom theme's HTML / CSS HelpThemeDesign parts are display components; they do not reach the form controls. The HTML編集 (HTML Editor) App is BASE's only official way into the HTML. It has a price: a theme built with that App stops receiving BASE's own shop-page updates — new features and bug fixes — automatically, and you maintain it yourself. You can only start from a blank sample or a designer theme bought in the Design Market; the free official themes cannot be used as a base. Whether the cart and buyer-details screens can be edited at all is not stated in the official help. BASE's help is published in Japanese only.
JP-FORM-FORCED-SIGNUPPer-product sale conditions / whether the シークレットEC (Secret EC) App or the age-restriction App is switched on HelpAdmin settingThe BASE cart offers exactly two paths — log in with PAY ID, or enter your details and buy as a guest — and guest purchase is the standard one. There is no setting that closes guest purchase shop-wide, so do not go looking for one. If a login was demanded, either that product requires a specific payment method or a PAY ID account, or the シークレットEC App has put a password on the whole shop. The second one makes the shop private; it is not a signup requirement. BASE publishes its help in Japanese only.
JP-FORM-LOGIN-WALLMembers-only / login required HelpAdmin settingIf the catalog can be public, turn that requirement off.
JP-UX-COOKIEConsent banner / cookie tool HelpAppName the dismiss control and keep it off primary CTAs on first paint.

JP-FLOW-UNEXPECTEDPopups / wizards HelpThemeDrop required first-visit modals, or make them dismissible.

JP-POLICY-CAPTCHABot defense / CAPTCHA settings HelpPlatformWe never bypass this. Human checks may stay. Allowlisting a consented diagnostic UA is a platform or WAF decision.
JP-POLICY-BOTWAF / bot defense HelpPlatformWhether the consented AgentQA-Bot User-Agent can be allowlisted is a platform or security setting.
JP-PERF-HYDRATIONTheme initial HTML HelpPlatformAn empty first paint is often a platform theme issue. Prefer a server-rendered theme.

Furigana, tokushoho, and similar stalls are not emitted by the current harness. They may be missed — they are not scored as zero.

Where to put the Agentrix verification tag

Meta tag: YesThe HTML Tag Manager app (listed at no cost in the app store) injects a custom tag into the head of every page except cart and checkout. No custom domain is needed — it works on the *.base.shop default domain as-is (neither the app page nor the help conditions it on a domain). If you do use a custom domain you also control the DNS and can add a TXT record (BASE does not sell domains; because a CNAME is required, the store URL must be a subdomain such as shop.example.com). Official help

We email the token to paste after you sign up. A DNS TXT record or a .well-known file works just as well — see site ownership on the pricing page.
