External Services

This plugin connects to the following external services.

Stripe Payments (optional)

When the site administrator configures Stripe API keys (Secret and Publishable) under Conference → Setup, and a participant chooses Stripe at checkout, the plugin:

• Loads Stripe.js from https://js.stripe.com on the registration page.
• Creates a PaymentIntent on Stripe’s servers via the Stripe PHP SDK.
• Stripe Elements (an iframe hosted by Stripe) collects the card data directly; the card number never touches the WordPress server.
• Optionally receives webhook callbacks from Stripe to confirm payment status.

What data is sent to Stripe:

• Payment amount and currency.
• Participant email address (for Stripe receipts).
• Billing details if provided by the participant.
• Registration ID and registration number as metadata.

When:

• Only when a participant selects Stripe as the payment method and submits the registration form.
• When Stripe sends a webhook back to the site (server-to-server callback).

IPAex Font Download (PDF generation)

To render Japanese text in PDF documents (invoice, receipt), the plugin needs the open-source IPAex Gothic and IPAex Mincho fonts. From the admin Dashboard you can install them with one click; the plugin then downloads the font files (one-time, per font). No user data is transmitted — it is a file download only. If the server cannot reach the download host, you can instead upload the .ttf files directly from the Dashboard (no external connection required).

• Download host (mirror maintained by the plugin author): https://cs24.biz/conference/fonts/
• Data sent: none (file download only)
• The download URL can be overridden via the conf_manager_font_source_url filter.
• Original font source / IPAex Font License (IPA, Information-technology Promotion Agency): https://moji.or.jp/ipafont/license/

Development / Building from source

The admin and public interfaces are built with React (JSX). The human-readable
source for the compiled, minified bundles build/admin-app.js and
build/public-app.js is shipped inside this plugin under the src/ directory:

• src/admin/ — source for build/admin-app.js (admin dashboard app)
• src/public/ — source for build/public-app.js (public registration / MyPage app)

Build toolchain: the project uses @wordpress/scripts
(a wrapper around webpack and Babel). The webpack configuration is included as
webpack.config.js, and all dependencies and build scripts are declared in
package.json (with package-lock.json for reproducible installs).

To rebuild the compiled assets from source:

1. Install Node.js 18+ and npm.
2. From the plugin directory, run npm install.
3. Run npm run build. This regenerates build/admin-app.js and
   build/public-app.js (and their *.asset.php dependency manifests).
   Use npm start for an unminified development watch build.

Third-party libraries bundled into the compiled JavaScript (all open source,
installed from the public npm registry and declared in package.json):

• @stripe/react-stripe-js and @stripe/stripe-js — Stripe Elements payment UI (MIT)
• html5-qrcode — QR code scanner used for participant check-in (Apache-2.0)

WordPress-provided packages (wp-element, wp-components, wp-api-fetch,
wp-i18n, react, react-jsx-runtime) are declared as externals and are NOT
bundled — they are loaded from WordPress core at runtime.
