Description

Pukulink lets you search for products, insert product cards, keep prices up to date, and track link clicks from within WordPress.

Works with both the Classic Editor and the Block Editor.
Search Amazon, Rakuten Ichiba, and Yahoo! Shopping, then insert a product card.
Save favorite Rakuten Ichiba and Yahoo! Shopping stores and search within a specific store.
Link products that you have confirmed are the same item across stores, then show each store’s price and retrieval date on one card.
Refine the search keyword used by stores that do not have a linked product. The card title remains unchanged.
Includes automatic price updates, per-card price visibility, sale labels, review links, and click tracking.
When Amazon Creators API eligibility is temporarily unavailable, Amazon search links can still be inserted.
Includes six templates: Standard, Compact, Large Card, Modern, Text Link, and Comparison Buttons.
Optionally show extra Amazon or Rakuten Ichiba product photos as a gallery on the Standard, Large Card, and Modern templates, with swipe, arrow buttons, and keyboard support. Each card can override the site setting to always show or always hide its gallery.
AI markers let you replace [pukulink_draft keyword="product name"] placeholders with product cards after reviewing search results. Each product is selected and confirmed by the user.
Optionally outputs schema.org Product/Offer JSON-LD.
Rakuten Ichiba and Yahoo! Shopping links can also use Moshimo Affiliate by importing IDs from Easy Link code.
The Product Health report lists products that may no longer be available.
Export settings, the product registry, history, and click totals as JSON.

In accordance with the Yahoo! Shopping API guidelines, Pukulink automatically displays the required Web Services by Yahoo! JAPAN attribution at the bottom of pages that show Yahoo! product information.

Posts store the portable [pukulink] shortcode. Affiliate URLs are assembled when a page is displayed, so changing a setting updates existing cards without editing each post.

Installation

Upload pukulink.zip from Plugins > Add New > Upload Plugin.
Activate Pukulink.
Open Settings > Pukulink and enter the credentials for the services you want to use.
Search for a product from the Add Pukulink button in the post editor or the Pukulink block in the Block Editor. Searching for “Product Link” also finds the block.

Pukulink 2.0.0 and later are a clean, independent plugin. Settings, history, click totals, and product cards from the pre-2.0 version are not migrated. Re-create any product cards you need with this version.

FAQ

Why can’t I search Amazon products?: Check the Creators API Client ID, Client Secret, Associate ID, and your Amazon Associates eligibility. Even when eligibility is temporarily unavailable, you can create an Amazon search link.
When are prices updated?: WP-Cron runs hourly and gradually refreshes products displayed within the last 30 days after their configured cache period has expired. On low-traffic sites, schedule wp-cron.php with your server’s cron service for more reliable updates.
Are settings migrated from an older version?: No. Pukulink 2.0.0 does not migrate the previous plugin’s settings or product cards. This keeps all identifiers consistent under the Pukulink name.
Why are Rakuten searches or price updates not working?: Support for the legacy Rakuten API ends on August 17, 2026. Register an application for the current Rakuten Web Service API and configure both the Application ID and an access key beginning with pk_. You must also register your site URL as an allowed website for the application.

Changelog

2.6.4

Added a per-card override for the image gallery (always show / always hide), matching the existing per-card price display option. You can now try the gallery on a single product before turning it on site-wide.

2.6.2

Added an optional image gallery for Amazon and Rakuten Ichiba products, with swipe, arrow buttons, and keyboard support. Turn it on under Display & Design, then choose “Include extra photos” for individual product cards when inserting them. Off by default; existing cards are unaffected.

2.5.5

Resolved all issues reported by the official Plugin Check tool: escaped the editor button output at the point of output, added a missing translators comment, and corrected nonce-verification annotations for two read-only admin query parameters. No functional or visual changes.

2.5.4

Prepared the WordPress.org distribution package: translated this readme into English, corrected external-service policy links, removed the obsolete manual translation loader, and excluded bundled Japanese translations and Japanese development documentation from the release ZIP. WordPress.org translations are loaded from translate.wordpress.org.

Used the original search term, rather than a long product title, for unlinked store search URLs. Unified the product-search modal layout across stores.
