It integrates with WooCommerce to submit invoices, validate customer TINs, and manage credit/refund notes. Key features: * Automatic invoice submission based on WooCommerce order status (completed, processing, or delayed “after X days”) * UBL 1.0/1.1 invoice generation, with optional digital signatures (PEM) for UBL 1.1 * TIN capture and validation in user profile and WooCommerce “My Account” * Background cron jobs for retries, delayed submissions, and status sync * Credit note and refund note creation linked to original invoices ### External Services This plugin connects to **third‑party external services** operated by LHDN (Lembaga Hasil Dalam Negeri / Malaysian Inland Revenue Board). Users should be aware of this before use. ### What the service is and what it is used for The plugin uses the **LHDN MyInvois API** (official Malaysian government service) to: * Submit invoices generated from WooCommerce orders * Validate Tax Identification Numbers (TIN) for customers * Retrieve invoice statuses and document details * Cancel documents and submit credit/refund notes ### Domains (where the service is hosted) API and portal domains are selected based on environment: * **Sandbox (Pre‑Production)** - API: `https://preprod-api.myinvois.hasil.gov.my` - Portal: `https://preprod.myinvois.hasil.gov.my` * **Production** - API: `https://api.myinvois.hasil.gov.my` - Portal: `https://myinvois.hasil.gov.my` ### What data is sent and when * **Invoice data** — When an order reaches the configured status (completed/processing or after the chosen delay), the plugin sends: - Invoice number, date, and monetary amounts - Buyer information (name, TIN, ID type, ID value, address, contact details) - Seller information (TIN, SST/TTX numbers, address, contact details) - Line items (products, quantities, prices, descriptions) - Tax information and industry classification codes * **TIN validation** — When a user submits or updates their TIN in their profile/ My Account, the plugin sends: - Tax Identification Number (TIN) - ID Type (e.g. NRIC, Passport, BRN) - ID Value * **Status and document requests** — Cron jobs and admin actions request invoice status and document details from the API. * **OAuth authentication** — Client ID and secret are sent to the token endpoint to obtain and refresh OAuth access tokens. Data is sent only when: * Orders are submitted to LHDN (automatically or manually) * Users explicitly validate their TIN details * The plugin syncs invoice statuses or documents (via cron or on‑demand) All communication with LHDN endpoints uses HTTPS and OAuth 2.0. ### Service provider and policies * **Provider:** Lembaga Hasil Dalam Negeri (LHDN / Malaysian Inland Revenue Board) * **Terms of use:** https://myinvois.hasil.gov.my/terms * **Privacy policy:** https://myinvois.hasil.gov.my/privacy ## Installation 1.
