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.

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.
