affilun is a WordPress plugin for managing affiliate product links used by Japanese websites. It stores products from Amazon Associates, Rakuten Ichiba, Yahoo! Shopping, Mercari, and other configured routes, then displays them as reusable product cards in posts.

The local plugin features do not require a license key, trial, paid plan, or usage quota. Product storage, product cards, provider settings, and basic affiliate-link generation run within WordPress.

You can optionally connect affilun Cloud for managed AI assistance, article drafting, link-health checks, campaign suggestions, affiliate-product suggestions, and plan information. These optional features are external SaaS services processed by affilun Cloud.

Main features

Store and manage affiliate product records in WordPress.
Display product cards with a Gutenberg block or shortcode.
Configure Amazon, Rakuten Ichiba, Yahoo! Shopping, Mercari, and ASP routing templates.
Generate a standard Amazon product-detail URL with the configured Partner Tag when an ASIN is stored.
Fetch discounted Amazon physical products daily and display priority brands before selected categories with a configurable shortcode.
Store button labels, display templates, link attributes, and provider display settings in WordPress.
Use optional Cloud features only when an affilun Cloud API key and eligible plan are configured.

affilun Cloud boundary

The plugin distributed through WordPress.org is a GPL-licensed WordPress plugin. Local product management, product-card rendering, saved settings, and basic link generation run within WordPress.

affilun Cloud is an optional external SaaS. Cloud features may include paid plans, usage limits, plan checks, Stripe Checkout, Cloud API-key issuance, AI assistance, article drafting, link-health checks, campaign suggestions, and affiliate-product suggestions. Local plugin features remain available without affilun Cloud.

The affilun Cloud server implementation, billing system, hosted processing, and external API relay services are not included in this plugin package. See https://affilun.st/ for Cloud terms, pricing, data retention, and deletion information.

External product images

Product cards and administration previews may display product-image URLs saved in WordPress. These URLs may point to provider, marketplace, affiliate-network, or CDN domains. When a page containing an external image is viewed, the visitor’s browser sends a request to that domain, which may receive the visitor’s IP address, user agent, referrer, and other request information.

Data stored in WordPress

affilun may store:

Provider settings, including Amazon credentials and Partner Tag, Rakuten credentials, Yahoo! credentials, Mercari afid, and enabled states.
Product records, including title, provider item ID, ASIN, price, availability, image URL, product URL, affiliate URL, synchronization state, and timestamps.
Daily Amazon discount snapshots stored separately from manually managed affiliate products.
Priority-brand names configured for Amazon discount synchronization and shortcode display.
Display settings, including templates, button labels, link attributes, and display options.
ASP routing settings and URL templates.
affilun Cloud settings, including Cloud API key, site ID, endpoint, selected plan, and connection state.
Operational data, including logs, sync jobs, audit events, link-health results, opportunity states, cached affiliate suggestions, local click events, and daily click/view aggregates.

API keys and affiliate identifiers are stored in the WordPress database and managed by administrators. They are not rendered on public pages.

ASP Routing

Yahoo! Shopping affiliate tracking is configured with a Yahoo Developer Client ID and a ValueCommerce free-text-link HTML snippet. affilun extracts and stores only the sid and pid values needed for link generation.

Advanced routing templates can also be configured for custom ASPs or migrations. Templates may use placeholders such as {url}, {encoded_url}, {provider}, and {product_id}.

When routing is enabled, a product-button URL may be transformed into the configured intermediary ASP URL. The site operator is responsible for confirming that each template complies with the relevant ASP rules and tracking requirements.

Uninstall

Deleting the plugin through WordPress runs uninstall.php.

The current uninstall policy removes secrets and operational options, including provider credentials, the affilun Cloud API key and connection settings, local click aggregate options, cron cursors, worker IDs, and scheduled affilun cron hooks.

Custom tables containing products, logs, audits, synchronization data, link-health data, analytics, and click aggregates are retained unless an explicit data-removal option is introduced in a future release. Back up required data before deleting the plugin.
