n8n-nodes-tracepass

This is an n8n community node. It lets you automate
TracePass — the EU Digital Product
Passport platform — in your n8n workflows.

TracePass generates compliant Digital Product Passports (DPPs) for EU
regulations (ESPR, the Battery Regulation, and more). This node lets
you create and manage products, passports, and GS1 EPCIS 2.0
supply-chain events directly from n8n — no code.

n8n is a fair-code licensed workflow automation
platform.

Installation

Follow the
community nodes installation guide
in the n8n documentation.

In n8n: Settings → Community Nodes → Install, then enter
n8n-nodes-tracepass.

Operations

The operations below mirror the node's nodes/TracePass/*Description.ts
files; if they ever disagree, the code is right.

Product

• Create — add a product to the catalogue
• Create Batch — create up to 100 products in one call, with partial
  success per item; the whole batch is counted against the daily write cap
  upfront (if it would exceed the cap, nothing is created — 429). Products
  are not billable on their own
• Archive — soft-archive a product (reversible, not deletion); blocked
  with 409 while any non-archived passport still references it
• Get — retrieve a product by ID
• Get Many — list products, with category / search filters
• Update — update a product's name, model, or description

Passport

• Create — create a Digital Product Passport (consumes a plan
  DPP slot — billable; opt in to overage with Confirm Overage
  Charge). For a repurposed, remanufactured or reused battery, add
  Lineage (JSON) under Additional Options to link the new passport
  to the original(s) (Battery Regulation Art. 77(7))
• Create Batch — create up to 100 passport shells in one call (each
  item: a product ID plus a GS1 GTIN + serial or an EN 18219 identifier
  scheme; battery passports accept only GS1 or ISO 15459). Field values are
  not accepted here — set them afterwards with Update Field. Partial
  success per item; consumes one plan DPP slot per passport
• Capture Measurements / Capture Measurements by Serial — push
  over-life battery data from your own equipment (state of health, cycle
  counts and the other Battery Regulation Annex XIII point 4 values) into a
  published battery passport; metered against the plan's monthly measurement
  allowance, and paid plans keep counting past it at no charge
• Get Measurements / Get Latest Measurements — read a battery
  passport's measurement history, or the newest value per field
• Get / Get by Serial — retrieve a passport by ID or by its
  serial number
• Get Many — list passports, with status / product filters
• Get QR / Get QR by Serial — render the passport QR code
  (SVG / PNG / JSON), optionally in the company brand colour or an
  explicit colour, by ID or by serial
• Get Snapshots — list a passport's immutability snapshots, newest
  first (one is written on publish and after every change to a non-draft
  passport), each with version, reason, actor, content hash and a
  re-verified hashValid; set As Of to get the version valid at a given
  moment instead
• Get Snapshot — the full archival record of one snapshot: the complete
  JSON-LD the passport asserted at that time, plus its content hash
  (re-verified on read)
• Compliance — get a three-tier compliance verdict (compliant /
  compliant_with_warnings / incomplete) with regulation-cited findings —
  missing required fields/parties, format issues, and per-category
  conditional rules
• Registry Readiness — check whether a passport would pass the EU DPP
  Registry's formal submission gate (mandatory fields present, correct
  formatting, a resolvable public link). The registry's mechanical
  pre-submission check, not the substantive compliance verdict. Battery only
• Get Condition Flags / Get Condition Flags by Serial — read the
  condition-classification flags for a passport — approved yes/no facts
  (e.g. battery: hasBMS, rechargeable, externalStorageOnly,
  isStationaryBess) that gate conditional legal duties
• Set Condition Flags / Set Condition Flags by Serial — set or
  clear condition flags (flag → true / false / null to remove).
  Warning: approving a flag may make additional fields required — an
  empty required field will block publishing with a conditional_missing
  error
• Update Field / Update Field by Serial — set the value of one
  passport field, by ID or by serial
• Suspend / Suspend by Serial — suspend a published passport
  (reversible), by ID or by serial
• Archive / Archive by Serial — archive a passport
  (irreversible — the public QR permanently 404s), by ID or by serial

The by-serial operations address a passport by your own serial number.
A serial is unique only within a GTIN, so if the same serial exists under
two GTINs in your account a serial-only call returns 409 — set the
optional GTIN (Disambiguator) field to resolve the passport exactly.

EPCIS Event

• Export / Export by Serial — export a passport's events as a
  GS1 EPCIS 2.0 document, by ID or by serial (included on Starter plans
  and up; the by-serial form takes the same optional GTIN disambiguator)
• Capture — submit EPCIS 2.0 events (requires the EPCIS add-on)
• Get Capture Job — poll an async capture job
• Query — query the EPCIS event store with the standard EPCIS
  query filters (requires the EPCIS add-on)

Scope

• Check — ask what EU law says for a product type matching the
  facts given: whether it needs a Digital Product Passport, from when,
  at which level, under which act and article, and the duties of each
  supply-chain role (manufacturer, importer, distributor). Not legal
  advice.
  Accepts an optional product category, role, act-namespaced facts
  (e.g. battery.use), placing date and precision, locale, and
  optional product ID / passport ID to pull in saved facts. Available
  on every plan, Free included. Counted against the scope-answer cap
  (≈100/day, 30/min burst), not the v1 daily read cap. 429
  scope_answer_cap with Retry-After past it.
• Get Catalogue Report — get the company-wide scope report: for
  every product and every distinct fact set among its passports,
  whether a passport is needed, from when, at which level and under
  which act. Filter by classification, category or Changed Only to
  see only rows whose answer changed in the most recent run. Use
  nextCursor to page through the full report (up to 500 rows per
  page). Requires Growth plan or above (scopeCatalogueEnabled); 403
  plan_upgrade_required below that. Counts one v1 daily read per
  page.

Template

• Get Many — list the DPP category templates with their field
  count, required-field count, governing regulation and version
• Get — get the full regulatory field schema for one category
  (every field with its key, label, type, required flag, access
  level and governing regulation reference)

Templates are read-only reference data — use them to discover what a
compliant passport in a category requires before creating products
and passports.

Credentials

The node supports both of TracePass's auth methods. On the node, pick
one in the Authentication dropdown — n8n then shows the matching
credential type (you only fill in the one you chose):

Access Token (API key) — the simplest. In the TracePass dashboard,
go to Developer → API Keys, create a key (it starts with tp_),
then create a TracePass API credential in n8n and paste it. Use
Test to verify the key before building a workflow. The whole
workspace is reachable (all-or-nothing).

OAuth2 — for when the workflow should act as a particular user with
only the access they granted. Register an OAuth app in the TracePass
dashboard under Developer → OAuth Apps (a public/PKCE client works —
no secret needed), then create a TracePass OAuth2 API credential in
n8n and click Connect: you approve the requested scopes on a
TracePass consent screen, and n8n stores + auto-refreshes the tokens.
Request only the scopes the workflow needs (e.g.
passports:read passports:write offline_access — keep offline_access
so n8n can refresh). The user can revoke the connection any time under
Developer → OAuth Apps → Connected Apps.

For both, the Base URL defaults to https://app.tracepass.eu —
change it only for a self-hosted or staging deployment.

Example workflows

Shopify → TracePass — on a new Shopify order, create a passport
(product mapped by SKU, serial = order ID), then email the QR code
to the customer.

Daily analytics digest — a Schedule trigger lists yesterday's
passports and posts a summary to Slack.

CSV → passports — read a CSV of serial numbers and create a
passport per row.

Compatibility

Requires n8n 1.x. Tested against the current n8n community-node API
(n8nNodesApiVersion: 1).
