Frontend widgets use the publishable key; server tasks use the secret key. To obtain keys, create an account on https://icpay.org and generate them in your dashboard. ### Source code and build This plugin includes a minified frontend script for the widget: assets/js/icpay- embed.min.js. Widget source (primary): https://github.com/icpay/icpay-widget SDK source (dependency): https://github.com/icpay/icpay-sdk Build notes (recommended): The minified icpay- embed.min.js is built from the open-source icpay-widget repository. To reproduce: 1. Clone icpay-widget and install deps (pnpm/yarn/npm supported): pnpm install 2. Build: pnpm build 3. Copy the generated minified widget bundle to this plugin at assets/js/icpay-embed.min.js. ### External service disclosure This plugin connects to the ICPay service operated by icpay, Inc. to process payments: – What: Payment creation and status updates. – When: When rendering the widget (publishable key) and when receiving webhooks; when syncing payments from your dashboard. – Data sent: Payment amounts, selected crypto asset, and optional metadata you configure( e.g., order ID). Webhook payloads contain payment status updates. Privacy Policy: https://icpay.org/privacy Terms of Service: https://icpay.org/terms #### Additional third-party services used by the widget (optional) * Identity (authentication): `https://identity.ic0.app` — opened only when a user chooses Internet Identity. No static assets are offloaded; it is an external login service. * On-ramp provider: `https://global.transak.com` (or `https://global-stg.transak. com` in non-production) — used only when the on-ramp modal is triggered. No static assets are offloaded; it is a payment service. No JS/CSS/images are loaded from remote CDNs by this plugin. All static assets ( scripts, styles, and images) used by the plugin UI are bundled and served locally within the plugin. The build script enforces this by rejecting known disallowed remote asset references. ## Blocks This plugin provides 1 block. * ICPay Widget ## Installation 1. Upload the `icpay-payments` folder to the `/wp-content/plugins/` directory, or upload the zip via Plugins Add New Upload. 2. Activate the plugin through the ‘Plugins’ menu in WordPress. 3. Go to Instant Crypto Payments Settings and enter your Publishable and Secret keys. 4. (Optional) Configure global defaults. 5. Use the Instant Crypto Payments block in the editor to insert widgets, or shortcodes if preferred. 6. Add a webhook endpoint in your ICPay account pointing to `/wp-json/icpay-payments/ v1/webhook`. This endpoint is public by design but securely verified using an HMAC- SHA256 signature header. ## FAQ ### Do I need my secret key on the frontend? No. Only the publishable key is exposed on the frontend. The secret key is used on the server for sync and API calls. ### Does it work without the WordPress.org directory? Yes, you can install from a zip. For automatic updates via WordPress.org, submit the plugin to the official directory. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Instant Crypto Payments” is open source software.

Amount column now shows the payment in its fiat currency when the widget used a non-USD currency (e.g.“ 10.00 GBP” instead of always “$12.00”). Fiat currency and amount-in-fiat are stored from the payment intent on sync. * Payment detail view: when the intent used a non-USD fiat, the amount is shown in that currency (e.g. “10.00 GBP”) in addition to or instead of the USD equivalent where appropriate. #### 1.3.7 * New: Payment currency (fiat) option for all widgets. Block editor shows a “Payment currency” dropdown (USD default; other currencies from API). Use a different fiat (e.g. EUR) for amount display and balance checks. When not set or set to USD, the option is omitted from the widget config. * Block editor: “Amount (USD)” label renamed to “Amount” for the Pay Button. * Shortcodes: all widget shortcodes now accept an optional `fiat_currency` attribute( e.g. `fiat_currency="EUR"`). #### 1.3.2 * New: Solana chain support. * New: Relay mode with per‑chain recipient addresses (IC, EVM, Solana). * New: Theme/overlay hardening so the wallet selector reliably appears above site UI. * New: X402 v2 improvements and UX updates. * Fix: Webhook and recheck verification now enforce relay rules and report terminal mismatches. * Fix: Amount USD inputs accept any positive decimal; validation moved to on‑blur. * Fix: Various minor compatibility and stability issues. #### 1.2.2 * Block editor: replaced “Accepted tokens” toggles with a searchable multi‑select“ Filter allowed tokens (optional)” UI. * Block editor: now shows chain name in brackets next to token symbol; selected tokens are sorted by chain then symbol. * Block editor: “Amount (USD)” accepts arbitrary decimals (step=any), e.g. 0.0005 or 1.12. * Block editor: label renamed “Component” “Widget Type”; default button label uses “crypto”. * Shortcodes/block render: removed deprecated “Disable button” and “Disable after success” flags. * Settings: added Tools section with “Clear ICPay payment history” button (with confirmation) to truncate local synced icpay payment records. * API/SDK integration: enriched public tokens response to include chain metadata used by the editor (chainName, chainShortcode, chainType, nativeSymbol, rpcChainId). * Documentation: note optional support for X402 (Coinbase) payments where enabled. #### 1.0.25 * Compliance updates: source links in headers/readme, nonce checks, SQL prepare fix, progress bar defaulting, moved Sync button to Payments page, webhook namespace switched to icpay-payments. ## Meta * Version **1.3.8** * Last updated **2 months ago** * Active installations **Fewer than 10** * WordPress version ** 6.0 or higher ** * Tested up to **6.9.4** * PHP version ** 7.4 or higher ** * Language * [English (US)](https://wordpress.org/plugins/icpay-payments/) * Tags * [bitcoin](https://pcm.wordpress.org/plugins/tags/bitcoin/)[crypto](https://pcm.wordpress.org/plugins/tags/crypto/) [donations](https://pcm.wordpress.org/plugins/tags/donations/)[payments](https://pcm.wordpress.org/plugins/tags/payments/) [paywall](https://pcm.wordpress.org/plugins/tags/paywall/) * [Advanced View](https://pcm.wordpress.org/plugins/icpay-payments/advanced/) ## Ratings No reviews have been submitted yet.
