DPPBuilder – Digital Product Passports for WooCommerce

DPPBuilder creates Digital Product Passports for your WooCommerce products, designed to help with EU Digital Product Passport requirements and providing comprehensive product traceability. The JSON output includes Schema.org Product markup and the UN/CEFACT UNTP DPP context to facilitate early interoperability.
This plugin is fully functional and unlimited. No subscriptions, API keys, or external services are required.

Disclaimer: The official EU Digital Product Passport (DPP) regulation and its JSON data format have not been finalized at the time of this plugin』s release. This plugin is intended for early adopters and developers who want to begin practicing and preparing for DPP implementation in WooCommerce. It uses the closest publicly available draft — the UN/CEFACT UN/Transport & Logistics Programme (UNTP) DPP v0.6.1 pre-release — and follows current best practices for early interoperability. Once the official specification is published, DPPBuilder will be updated to reflect it.

Key Features:

• One‑Click Passport Generation – From the WooCommerce product editor, generate a JSON Digital Product Passport on demand
• Human‑Readable Product Page + QR Code – Create a product DPP page and a QR PNG that links to it; add the QR anywhere in your store
• REST API Access – Opt-in public endpoint (disabled by default) to fetch passport data: /wp-json/dppbuilder/v1/passport/{product_id}
• Manufacturers Directory – Add/search manufacturers, set logos and locations, and display country flags; associate with products
• Materials & Compositions – Create custom materials, search and relate them to products for transparent composition data
• Comprehensive Product Data – Support for GTIN, manufacturing details, batches, origin, warranty and more
• JSON‑LD (Product) Output – Optional schema output to enhance SEO with structured data
• UN/CEFACT UNTP Alignment – Includes UNTP DPP JSON-LD context and conformsTo metadata (v0.6.1 pre-release) for closest-available alignment
• No External Services – Works entirely within your site; no accounts, no external APIs required
• WooCommerce Ready – Compatible with modern Woo features (including HPOS)

Perfect for:
* E-commerce businesses needing EU compliance

* Sustainability-focused brands
