<h3>External services</h3>
This plugin connects to Allscale’s API at <code>https://openapi.allscale.io</code> so your customers’ payments can be created, confirmed, and settled to your wallet. Specifically:
What is sent to Allscale, and when:
<ul>
<li>On settings save and on every “Test connection” click: the API key and a signed <code>GET /v1/test/ping</code> request — verifies the credentials are correct without sending order data.</li>
<li>When a customer clicks “Place order” with Allscale selected: a signed <code>POST /v1/checkout_intents/</code> with the order’s total amount in cents, currency (or stable-coin enum), your store’s order number, an order description (the names of items in the cart, truncated), the customer’s WooCommerce user ID and billing name, and the WooCommerce thank-you URL to redirect them back to after payment.</li>
<li>When the customer lands back on the thank-you page: a signed <code>GET /v1/checkout_intents/{id}</code> to read the on-chain transaction details and reconcile the order.</li>
</ul>
What Allscale sends back, and when:
<ul>
<li>Hosted checkout URL — the page your customer is redirected to to actually pay.</li>
<li>Webhook callbacks — when an on-chain payment confirms, Allscale POSTs a signed message to <code>https://your-site.com/wc-api/allscale_checkout</code> containing the transaction hash, chain ID, the on-chain settled amount in USDT, and the payment method type. The plugin verifies the HMAC-SHA256 signature before applying any state change.</li>
</ul>
Service terms and privacy:

<li>Allscale’s terms of service: <a href="https://www.allscale.io/agreement" rel="nofollow ugc">https://www.allscale.io/agreement</a></li>
