No third party holds your money. No account freezes. * **Low fees.** 0.6% per transaction with a $0.10 minimum (vs. ~3% on traditional processors). * **Instant settlement.** On-chain USDT — no waiting days for payouts. * **Permissionless setup.** Sign up, paste your credentials, start accepting payments. #### Features * Native WooCommerce payment gateway. * HMAC-SHA256 request signing and webhook verification (timing-safe). * Test-connection button + automatic credential validation on save. * Per-order Allscale Payment meta box: tx hash with block-explorer link, payment- method type, paid / fee / net breakdown. * Webhook health observation: last-received timestamp, first-webhook celebration, stale-webhook warning. * HPOS compatible. Block-based checkout compatible. * Full i18n with text domain `allscale-checkout`. #### Requirements * WordPress 5.8+ * WooCommerce 6.0+ * PHP 7.4+ * An [Allscale account](https://allscale.io) with Commerce enabled ### External services This plugin connects to **Allscale’s API at `https://openapi.allscale.io`** so your customers’ payments can be created, confirmed, and settled to your wallet. Specifically: **What is sent to Allscale, and when:** * _On settings save and on every “Test connection” click:_ the API key and a signed` GET /v1/test/ping` request — verifies the credentials are correct without sending order data. * _When a customer clicks “Place order” with Allscale selected:_ a signed `POST/ v1/checkout_intents/` 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. * _When the customer lands back on the thank-you page:_ a signed `GET /v1/checkout_intents/{ id}` to read the on-chain transaction details and reconcile the order. **What Allscale sends back, and when:** * _Hosted checkout URL_ — the page your customer is redirected to to actually pay. * _Webhook callbacks_ — when an on-chain payment confirms, Allscale POSTs a signed message to `https://your-site.com/wc-api/allscale_checkout` 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. **Service terms and privacy:** * Allscale’s terms of service: [https://www.allscale.io/agreement](https://www.allscale.io/agreement) * Allscale’s privacy policy: [https://www.allscale.io/policy](https://www.allscale.io/policy) Using this plugin makes your WooCommerce store an integration partner of Allscale. By installing and configuring it, you agree to Allscale’s terms. ### Privacy This plugin does not collect any analytics, telemetry, or user data on its own. It does not “call home” to allscale-io or any third party other than the Allscale API documented above. **Personal data this plugin transmits to Allscale** for the purpose of processing each order: * The customer’s WooCommerce user ID (an internal numeric ID, only if they’re a logged-in customer) * The customer’s billing first + last name * The order number and total amount * A short description of the items in the order (product names, truncated to 200 characters) **Personal data this plugin stores locally** in the WordPress database, on each order: * The Allscale checkout intent ID * The on-chain transaction hash (public blockchain data) * The settled amount, fee, and net amount in USDT * The chain ID and payment-method type No card numbers, no wallet seed phrases, no private keys, and no email addresses are sent or stored by this plugin. ## Screenshots [⌊The "needs WooCommerce" notice that appears if the plugin is activated on a site that doesn't yet have WooCommerce — one click installs or activates it.⌉⌊The "needs WooCommerce" notice that appears if the plugin is activated on a site that doesn't yet have WooCommerce — one click installs or activates it.⌉[ The “needs WooCommerce” notice that appears if the plugin is activated on a site that doesn’t yet have WooCommerce — one click installs or activates it.

Upload the plugin ZIP via _Plugins Add New Upload Plugin_. 2. Activate the plugin. 3. Go to _WooCommerce Settings Payments Allscale Checkout_. 4. Paste your API key and secret from your Allscale dashboard. 5. Click **Test connection**, then **Save changes**. 6. Copy the webhook URL shown in settings and paste it into your Allscale store’s webhook field. ## FAQ ### Does sandbox mode work? Sandbox mode has been retired. To test without real payments, create a **test store** in your Allscale dashboard and use its credentials. Both test and production stores share the same `openapi.allscale.io` base URL. ### Can the plugin configure the webhook URL automatically? No — Allscale does not expose webhook-management API endpoints. The merchant must paste the URL into the Allscale dashboard manually. The plugin shows when a webhook was last received so misconfigurations surface quickly. ### Are automatic refunds supported? No. Allscale is non-custodial; funds settle directly to your wallet. To refund a customer, send the amount back from your wallet, then update the order status in WooCommerce. ### Which currencies are supported? USD, AUD, CAD, CNY, EUR, GBP, HKD, JPY, SGD. You can also enable **native USDT pricing** for crypto-first stores. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Allscale Checkout” is open source software.

The plugin is now considered production-ready after the v0 hardening cycle. No breaking changes from 0.0.5 — existing settings, credentials, and order meta carry over untouched. * Plugin name simplified to “Allscale Checkout” (dropped the redundant “for WordPress” suffix). Slug, class names, namespaces, option keys, hook names, and the text domain are unchanged. * Compatibility verified with WordPress 7.0 and WooCommerce 10.8. * Hardening: admin asset-enqueue now unslashes and sanitizes the `$_GET` page-detection values. * Plugin Check pass: form-control output now routed through `wp_kses` allowlist, translator comments repositioned for i18n linting, removed the discouraged `load_plugin_textdomain` call (WordPress.org auto-loads translations) and the now-unused `Domain Path` header, and trimmed the readme short description to 150 characters. * Review prep: moved the thank-you polling and setup-wizard inline scripts into enqueued JS files, removed the default customer-facing “Powered by” attribution from the gateway description (admins can add their own), and corrected the terms/ privacy URLs. #### 0.0.5 * Packaging hygiene: release ZIPs now exclude dev-only content (`.wordpress-org/` marketplace assets, internal `docs/`, dev-facing `README.md`) via a `.distignore` file. v0.0.4 ZIPs accidentally bundled all of that — merchants now get only the runtime code. No code-behavior changes. #### 0.0.4 * WordPress.org submission prep: added `== External services ==` and `== Privacy ==` readme sections required by WordPress.org for any plugin that communicates with an external API. Added `== Screenshots ==` section referencing the four images in `.wordpress-org/`. No code-behavior changes. #### 0.0.3 * **Renamed**: plugin headline framing changed from “for WooCommerce” to “for WordPress”. The plugin still requires WooCommerce (and still ships as a WC payment gateway under the hood) — that’s now positioned as a dependency rather than the marketing headline. Class names, namespaces, option keys, hook names, and the text domain are unchanged. * GitHub repository renamed from `allscale-checkout-woocommerce` to `allscale-wordpress- plugin`. Old URLs continue to redirect via GitHub’s rename mechanism. #### 0.0.2 * Remove `Api_Client::get_intent_status()` — dead code, never called (the return- URL fallback uses `get_intent_details` for full fields). Restore in 5 lines if a future polling path needs it. * Documentation accuracy: clarify in architecture.md that `Admin::render_notices` ships 4 notice types (settings save result, first webhook, sandbox migration, credentials missing) and the other 3 from the design brief live in their own surfaces (WC-required notice in `Plugin`, currency-unsupported inline on the settings page, activation/get-started via the setup wizard). #### 0.0.1 First pre-release of the AllScale Checkout rewrite. Deliberately labeled v0 — not yet production-stable, expect rough edges. Major changes vs the prior 0.1.x community beta: * Sandbox toggle removed (Allscale API consolidated to one base URL — use test- store credentials to test). * Status enum expanded from 6 to all 12 documented Allscale states. * Return-URL fallback now reads full intent details (the 0.1.x fallback used the wrong endpoint and never worked correctly). * `redirect_url` moved to top level; `user_id` / `user_name` now sent. * Allscale error codes mapped to user-facing copy. * 0.1 USDT minimum payment enforced up-front. * Settings save validates credentials via `/v1/test/ping` before storing them. * New: 4-step setup wizard on first activation. * New: Test connection button in settings (AJAX-backed). * New: Allscale Payment meta box on each order — status pill, paid/fee/net breakdown, tx hash with block-explorer link, payment-method type, chain badge. * New: Front-end thank-you status block (confirmed / pending with auto-refresh / failed). * New: Webhook health observation (last-received timestamp, first-webhook celebration, stale-after-7-days warning). * New: Native USDT pricing opt-in for crypto-first stores. * New: Branded “needs WooCommerce” notice with one-click Install or Activate CTA. * Fixed: Webhook handler now registered unconditionally on `init`, no longer dependent on the gateway constructor running. * Fixed: `mb_strimwidth` for order descriptions — CJK / emoji product names no longer get sliced mid-character. * Fixed: Order_Locker mutex around state mutations — webhook + return-URL fallback can’t race. * Fixed: Late failure-state webhooks no longer revert already-paid orders. * Fixed: `cancelled` added to terminal-status exclusion. * Fixed: Gateway and Blocks_Integration classes now lazy-loaded after their WooCommerce parents are confirmed available — avoids a fatal when this plugin loads before WooCommerce. * Full i18n with text domain `allscale-checkout`. ## Meta * Version **1.0.0** * Last updated **3 days ago** * Active installations **Fewer than 10** * WordPress version ** 5.8 or higher ** * Tested up to **7.0** * PHP version ** 7.4 or higher ** * Tags * [crypto](https://wordpress.org/plugins/tags/crypto/)[payment gateway](https://wordpress.org/plugins/tags/payment-gateway/) [stablecoin](https://wordpress.org/plugins/tags/stablecoin/)[USDT](https://wordpress.org/plugins/tags/usdt/) [woocommerce](https://wordpress.org/plugins/tags/woocommerce/) * [Advanced View](https://wordpress.org/plugins/allscale-checkout/advanced/) ## Ratings No reviews have been submitted yet.
