uniple

uniple checkout for WooCommerce lets merchants accept JPYC, a Japanese yen stablecoin / electronic payment instrument (電子決済手段), through uniple’s hosted checkout.
Shoppers choose the uniple payment method in WooCommerce and are redirected to the uniple checkout page. uniple handles wallet connection and settlement, then returns the shopper to the WooCommerce order-received page. Payment confirmation is applied through a signed webhook, with a server-side session lookup fallback when the return page is reached before the webhook arrives.
Features:
<ul>
<li>Redirect-only WooCommerce payment gateway.</li>
<li>Classic checkout and Cart / Checkout Blocks support.</li>
<li>High-Performance Order Storage (HPOS) compatibility.</li>
<li>HMAC-SHA256 signed webhook verification.</li>
<li>Atomic webhook idempotency lock and event history.</li>
<li>Return URL order key verification and live lookup fallback.</li>
<li>Masked API key and webhook secret fields in the WooCommerce admin.</li>
</ul>
This plugin is built for WooCommerce stores. It is not developed by, affiliated with, or endorsed by WooCommerce or Automattic.
<h3>How to obtain an API key</h3>
uniple checkout requires a merchant account with uniple. Apply for an account at:
https://forms.gle/b8kwVZeynA1ffV8j6
After your application is approved, uniple will issue your API key and webhook secret, which you enter in the plugin settings (WooCommerce → Settings → Payments → uniple checkout (JPYC)).
<h3>External services</h3>
This plugin connects to the uniple hosted checkout API. The default service endpoint is <code>https://uniple.io</code>; the settings screen also permits <code>https://dev.uniple.io</code> for test use.
The plugin sends data to uniple only when it needs to create or verify a checkout session:
<ul>
<li>When a shopper places an order with the uniple payment method, the plugin sends <code>POST /api/merchant/checkout/sessions</code> to the configured uniple API base URL.</li>
<li>The session creation request includes the order total as <code>amountJpyc</code>, the WooCommerce order ID as <code>clientReferenceId</code>, the order description / order number, the configured merchant label, a one-line item summary, the success URL, the cancel URL, and the webhook URL.</li>
<li>The session creation request also includes the merchant API key in the <code>Authorization</code> header and a plugin <code>User-Agent</code> containing the plugin version, WordPress version, and WooCommerce version.</li>
<li>When the shopper returns from hosted checkout before the webhook has completed the order, the plugin may send <code>GET /api/merchant/checkout/sessions/{sessionId}</code> to verify the session status. This request includes the uniple session ID, the merchant API key, and the same plugin <code>User-Agent</code>.</li>
<li>uniple sends payment webhooks back to the store at <code>/wp-json/uniple/v1/webhook</code>. The plugin verifies the webhook signature locally with the configured webhook secret.</li>
</ul>
The plugin does not send full billing addresses, shipping addresses, customer account details, card details, wallet private keys, or browser cookies to uniple.
