Batch registration file for the EU DPP Registry.

Builds the batch file an economic operator uploads to the EU DPP Registry, as XML. Sibling of the JSON-LD and EPCIS tenant exports.

Publishing a passport does not register it. The duty to register sits with the economic operator placing the product on the market (Reg (EU) 2023/1542), and TracePass has no registry client. This endpoint hands over the payload already in the shape the registry accepts, so the step the operator owes is an upload rather than a data-assembly exercise.

Batteries only — BATTERIES is the only product group the registry offers, so passports in other categories are excluded rather than exported into a group the registry would reject. The response reports how many were left out, so the caller is not guessing.

Published passports only: an unpublished passport's link does not resolve, and the registry probes it mechanically.

At most 100 items per file.

Not API-key reachable. Auth is dashboard JWT with the admin role — the same privileged-action gate as the other tenant exports. There is deliberately no plan gate: this is the customer's own regulatory obligation, and putting a paywall between them and a duty they cannot otherwise discharge is not a trade worth making.
