CIHWEB Anywhere Cart

CIHWEB Anywhere Cart lets you place a buy button anywhere in an existing WordPress post or page. You do not rebuild your site as a shop.

Register one product and you get a dedicated sales page URL and a QR code for that single product. Share the URL, or drop a block or shortcode below an article and that article becomes the sales page. Buyers check out without creating an account.

This is not a full shopping cart. One order buys one product (quantity and quantity-discounts are supported). For a set, register a single “set” product. If you need a real multi-product cart, a full e-commerce plugin is a better fit. CIHWEB Anywhere Cart is “a quiet payment window you can place in the middle of an article.”

Payment methods (each is off by default; the owner turns on what they need)

• Bank transfer — no approval and no external sign-up. Works today. Order → you receive it → confirm the deposit → mark as paid → the buyer gets a thank-you mail.
• Stripe (credit card) — standard hosted checkout. The buyer pays on Stripe’s own page; card numbers never pass through your site. Payment is confirmed automatically by webhook. Requires your Stripe API key.
• JPYC (stablecoin on Polygon, via CIHPAY) — enabled by pasting a shop configuration issued by CIHWEB.

Highlights

• A single product becomes a sales page, a block, shortcodes and ad-sized banners (728×90 / 300×250, etc.).
• “Returned from the payment page” does not mean “paid.” Returned orders are marked pending; the deposit is confirmed by webhook or by the owner. The same notification arriving many times still marks paid and sends mail only once (idempotency key).
• Legal pages (Specified Commercial Transactions Act notice, Terms, Privacy Policy) are generated for you — no need to build static pages.
• A built-in contact form, with spam protection that uses no external service and no CAPTCHA.
• Postal-code to address auto-fill for Japan, using bundled data — no external lookup service.
• QR codes are generated inside the plugin (no external image service).
• An “Ask AI how to use it” screen: copy a help prompt to paste into ChatGPT or Claude.

Order status is shown as a simple to-do list (confirm the transfer / ship it / done).

External services

This plugin connects to outside services only when the store owner enables the matching payment method. Every payment method is off by default. No data is sent unless a customer actually chooses that method.

Stripe (credit-card payments) — optional
When Stripe is enabled and a customer chooses to pay by card, the plugin creates a Checkout Session by sending the order amount, an order reference and the product name to the Stripe API (https://api.stripe.com). The customer is then redirected to Stripe’s hosted checkout page (https://checkout.stripe.com) to enter card details; card numbers never pass through your site. Payment is confirmed back to your site by a Stripe webhook, whose signature the plugin verifies. Your own Stripe secret key and webhook signing secret are required.

CIHPAY / JPYC (stablecoin payments on Polygon) — optional
When JPYC is enabled and a customer chooses it, the plugin sends the order amount, an order reference and the return URL (HMAC-signed with your shop secret) to the CIHPAY gateway (https://cih-pay.com) and redirects the customer there to pay. Payment is confirmed back by a signed webhook. A shop configuration issued by CIHWEB is required.

Japan Post postal-code data — optional, only on demand
Postal-code lookups use data bundled with the plugin; no external service is contacted for a lookup. Only if the owner clicks “Import from Japan Post” does the plugin download the latest ken_all postal-code file from Japan Post (https://www.post.japanpost.jp). Nothing is uploaded; it only downloads that file.
