Integrating the Digital Product Passport into your systems

A Digital Product Passport is not a PDF you upload once — it is a structured, regulated data record that must stay accurate for years while your product data keeps changing in ERP, PIM and PLM systems. That makes the DPP an integration problem as much as a compliance one. This page covers what a DPP API should actually offer, how the data flows work in practice, and when building your own passport infrastructure makes sense — and when it clearly does not.

In one line: treat the DPP platform as a compliance layer fed by your existing systems of record — the API surface you need is passport CRUD, field-level updates, status webhooks, standards-compliant output and registry submission, not another master-data silo.

Where the DPP sits in your architecture

Your ERP, PIM and PLM systems remain the systems of record: item masters, bills of materials, supplier data, certificates, test reports. The DPP platform sits downstream as a compliance layer — it assembles regulated data points from those sources into a passport per product (or batch, or item, depending on the delegated act), publishes it behind a data carrier, and keeps it accessible for the product’s regulated lifetime.

The practical integration pattern is one-directional for most fields — product data flows from your systems into the passport — with events flowing back the other way: a passport passes validation, gets sealed, gets registered, or changes status. Trying to make the DPP platform a second master-data system is the most common design mistake; map fields once, then automate the sync.

What a DPP API should offer

Passport CRUD — create, read, update and archive passports programmatically, so a new SKU in your PIM can become a draft passport without manual re-entry.
Field-level writes — update a single data point (a new test report, a corrected weight) without resubmitting the whole passport, preserving the audit trail of what changed and when.
Webhook events on status changes — notifications when a passport is validated, sealed, registered, flagged or updated, so your ERP or ticketing system reacts without polling.
Standards-compliant output — machine-readable passport data (JSON-LD is the direction of travel for interoperability) so regulators, customers and recyclers can consume it, not just view it.
GS1 Digital Link resolution — the QR or Data Matrix on the product resolves through a GS1 Digital Link URI to the right passport view for each audience.
Registry submission — filing the required identifiers with the EU DPP registry as part of the publish flow, not as a separate manual step.

Build vs buy, honestly

Building passport generation in-house looks feasible at first: it is "just" structured data behind a QR code. The costs sit elsewhere. Passports must remain accessible for the product’s regulated lifetime — up to 15 years, with backup custody — which turns a side project into a long-term hosting and availability commitment. Authenticity expectations point to qualified electronic seals (eIDAS), which means certificate management and a sealing pipeline. Registry conformance, carrier standards and per-product-group delegated acts all keep moving, so the specification you build against this year will not be the one you are audited against later.

The honest split: if passports are your product, build. If passports are a compliance obligation attached to your actual product, buying a platform and integrating it through an API is almost always cheaper over the lifetime of the duty — your engineering effort goes into the integration, which you own and understand, rather than the regulated infrastructure underneath it.

How this works with PassPer

PassPer exposes a REST API for creating and updating passports and webhooks for status events, so passports can be driven from your existing systems rather than a browser tab. The platform handles the regulated layer underneath: AI extraction from the documents you already have (spec sheets, certificates, supplier declarations) with human review, eIDAS qualified sealing (QTSP onboarding in its final stage), GS1 Digital Link QR generation, EU registry filing and EU-sovereign hosting for the passport’s full retention period. A typical integration starts small — sync one product line, watch the webhook events, then extend. The free 21-day pilot is enough to build and test that first sync end to end.

Frequently asked questions

Do we need a real-time integration, or is a periodic sync enough?

For most products a periodic sync is fine: passport data changes when your product data changes, which is rarely minute-by-minute. Real-time matters mainly for status events — knowing immediately when a passport is registered or flagged — which is what webhooks are for. A daily field sync plus webhooks covers the large majority of cases.

Which system should be the source of truth for passport data?

The systems that already hold the data: PIM for product attributes, PLM for materials and engineering data, ERP for supplier and logistics data, document stores for certificates. The DPP platform should consume from these, not replace them. If a field has no clear owner internally, fix that before automating — the passport will only be as accurate as its source.

Can we build the passport infrastructure ourselves?

Technically yes, and for some businesses it is the right call. But be honest about scope: long-term availability with backup custody, eIDAS qualified sealing (QTSP onboarding), GS1 Digital Link carriers, registry conformance and per-product-group rules that keep evolving. That is regulated infrastructure, not a sprint — most operators are better served integrating a platform via API.

What data format do passports use?

Delegated acts define the required data points per product group; interoperability work points towards machine-readable, linked-data formats such as JSON-LD, with GS1 Digital Link as the carrier standard for the QR or Data Matrix on the product. A good platform outputs standards-compliant data so you are not locked to one vendor’s schema.
