PayPlug OAuth2 payments for HikaShop shops

Payment processing is not a complete e-commerce feature in Joomla core. Joomla provides the application framework, users, forms and extension system, while HikaShop supplies the shop, cart and checkout; connecting that checkout to a particular payment provider normally requires a HikaShop payment plugin. A template override can change how checkout looks, but it cannot by itself authenticate with PayPlug, receive payment notifications or reconcile transaction status. This extension goes beyond presentation by handling the PayPlug connection, redirecting customers to its hosted payment page and, according to the listing, processing return and notification events, refunds and test-mode payments. It uses the OAuth2 clients now issued through the PayPlug portal rather than the older secret-key setup.

It is aimed at a HikaShop store selling to customers who can use PayPlug's available payment methods, particularly a business already operating with a PayPlug account. The listing says payments are limited to euros and that the plugin works with all HikaShop editions. A Joomla site without HikaShop, a shop using another payment provider, or a non-commerce site has no obvious use for it.

The extension is listed as a free download under the payment gateway section, with a GPLv2-or-later licence. The developer is Hikari Software Team; the directory lists 88 other extensions from that developer, while this listing has no reviews. Before installation, check PayPlug's country, currency and method eligibility, the account fees, and whether the provider's current OAuth2 and notification requirements match the plugin. The listing provides no documentation, and does not explain its support process, update policy, or the precise Joomla-version scope beyond its broad compatibility claims.
