The customer sees the invoice inside a normal WordPress page, so the active theme remains responsible for the header, footer, trust badges, navigation, and other site elements. The plugin works without WooCommerce for manual-amount invoices. If WooCommerce is active, administrators can search products by name or SKU, choose quantities, and add those products to an invoice. Product prices are read again on the server when the invoice is created and saved as a snapshot, so browser-submitted prices are not trusted and later catalog price changes do not alter an existing invoice. Features include: * Manual-amount invoices. * Optional WooCommerce product search by name or SKU. * Server-side product-price snapshot at invoice creation time. * Configurable fixed shipping amount, enabled per invoice. * Public invoice page rendered through a shortcode inside the active theme. * ZarinPal payment Request, Verify, and Inquiry integration. * Server-side amount verification and stored-Authority matching. * Admin-only manual re-verification for recovery after temporary API/callback errors. * Optional, redacted rolling debug logging stored in WordPress (disabled by default). * WordPress Privacy Tools support for exporting customer invoice data and erasing contact fields by email. * Public invoice URLs request no-cache and no-index behavior. * Optional data removal on uninstall (disabled by default). * Backward-compatible migration from the previous 1.4.x private build. * No PDF generation. * No telemetry sent to the plugin author. This plugin is an independent integration and is not an official ZarinPal plugin. #### External service disclosure This plugin connects to **ZarinPal**, an external payment service, only when payment- related actions require it: * When a customer starts a payment, the plugin sends the configured merchant ID, invoice amount, currency, invoice description, callback URL, invoice/order ID, and optional customer mobile/email fields to ZarinPal. * When a payment callback is received, the plugin sends the stored merchant ID, stored invoice amount, and stored Authority to ZarinPal’s Verify API. * When an administrator explicitly clicks Inquiry, the plugin sends the merchant ID and stored Authority to ZarinPal’s Inquiry API. A ZarinPal merchant account and Merchant ID are required to accept payments. Service website: https://www.zarinpal.com/ Terms of service: https://www.zarinpal.com/terms Privacy / information security policy: https://www.zarinpal.com/policy The plugin author does not receive payment data, customer data, telemetry, or analytics from sites using this plugin. #### WooCommerce notes WooCommerce is optional. When enabled, this plugin reads product/variation names, SKU values, and current prices to build invoice line items. It does **not** create a WooCommerce order, reserve stock, apply coupons, calculate shipping methods, or run WooCommerce checkout. The invoice stores its own product-price snapshot. WooCommerce currency is supported directly when it is IRR (Rial) or a Toman-style currency code such as IRT/TMN. Developers can provide another conversion multiplier with the `ezinv_woocommerce_price_to_irr_multiplier` filter. ## Installation 1. Upload the `tahanoa-invoice-links-for-zarinpal` folder to `/wp-content/plugins/`, or upload the plugin ZIP from **Plugins > Add New > Upload Plugin**. 2. Activate **Tahanoa Invoice Links for ZarinPal**. 3. Create a normal WordPress page, for example `/payment/`. 4. Put the shortcode `[ezinv_invoice]` in that page. The previous `[ezi_invoice]` shortcode remains supported for migration compatibility. 5. Go to **Invoices > Settings**. 6. Enter the 36-character ZarinPal Merchant ID. 7. Select the WordPress page that contains the invoice shortcode. 8. Optionally set the business name, fixed shipping amount, debug logging, and uninstall- data preference. 9. Go to **Invoices**, create an invoice, then copy its public link and send it to the customer. #### Upgrading from private version 1.4.x Deactivate the previous 1.4.x private plugin before activating this public-directory build. Existing invoice data stays in the same `easy_zarinpal_invoices` table, and known `ezi_*` settings are migrated to the new `ezinv_*` option names where possible. Existing pages using `[ezi_invoice]` continue to render. Because the public-directory build uses a new plugin folder/slug, do not keep the old private build active at the same time. ## FAQ ### Will the invoice hide my site’s header or footer? No. The plugin does not replace the WordPress template. The invoice is rendered only where the shortcode is placed inside a normal published page, so a properly coded theme continues to control the header and footer. ### Can a visitor change the amount in the browser before paying? Changing HTML or JavaScript values cannot change the amount used by the gateway. Manual amounts are saved by an authorized administrator, WooCommerce product prices are re-read server-side when the invoice is created, and Request/Verify use the amount stored in the database. ### Can a fake callback URL mark an invoice as paid? No. Callback query parameters alone never mark an invoice as paid. The callback Authority must match the Authority previously stored for that invoice, and a successful server-to-server ZarinPal Verify response is required before the local status becomes Paid. ### Why is there a Re-verify button in the admin? A bank payment may complete while the callback site request or Verify API call encounters a temporary network problem. Re-verify lets an authorized administrator retry ZarinPal Verify using the invoice’s stored amount and Authority. It is protected by capability checks and an invoice-specific nonce. ### Does Inquiry confirm a payment? No. Inquiry only records the state reported by the Inquiry endpoint. It never marks an invoice paid. Payment confirmation is performed only by Verify. ### What does debug logging store? Logging is disabled by default. When enabled, the plugin stores a rolling list of up to 100 redacted gateway events in a non-autoloaded WordPress option. Its logger intentionally excludes Merchant IDs, invoice tokens, Authorities, card numbers, customer names, email addresses, and phone numbers. Administrators can clear the stored log from the settings screen. ### What personal data can be stored? Depending on invoice fields used, the WordPress database can store customer name, mobile number, email address, invoice line items, amounts, masked card number, payment state, and gateway reference ID. WordPress privacy-policy helper text is registered by the plugin. The WordPress personal-data exporter can export matching invoice data by customer email, and the eraser removes customer name/mobile/email while retaining financial transaction records. See the External service disclosure section for data sent to ZarinPal. ### Does deleting the plugin delete invoices? Not by default. In **Invoices > Settings**, administrators can explicitly enable deletion of plugin settings and invoice tables when the plugin is deleted. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Tahanoa Invoice Links for ZarinPal” is open source software.
