REST, GraphQL and JSON-LD

The public APIs expose only passports with status published. They are anonymous endpoints, so treat every published payload field as public information.

REST by SKU

GET /rest/V1/dpp/passport/{sku}
GET /rest/V1/dpp/passport/{sku}/jsonld

The first endpoint returns the passport service object. The second returns a JSON string containing formatted JSON-LD. An optional storeId query value selects store context.

If the SKU does not exist or no published record matches, the service returns null.

REST listing

GET /rest/V1/dpp/passports?searchCriteria[pageSize]=20&searchCriteria[currentPage]=1

Magento search criteria can filter, sort and paginate the result. The service always adds a Published filter, even if the caller requests another status.

GraphQL

query PublishedPassport {
  dppPassportBySku(sku: "NORTHSTAR-TEXTILE-410", storeId: 1) {
    passport_id
    template_code
    version
    espr_category
    country_of_origin
    dpp_payload
    completeness_score
  }
}

The query returns null when no published passport matches. The payload field is a JSON string rather than a nested GraphQL object.

JSON-LD content

Formatted JSON-LD contains:

• a schema-oriented context plus template-specific vocabulary entries;
• a public identifier URL;
• SKU, GTIN, manufacturer, batch and serial identifiers when available;
• store issuer information;
• status, version and publication dates;
• category, origin and HS code when available;
• the decoded passport payload;
• public page and QR links.

Integration checklist

• URL-encode SKUs used in REST paths.
• Pass the intended store ID in multi-store integrations.
• Handle null and 404 outcomes without retry loops.
• Treat dpp_payload as untrusted external JSON in consumers.
• Cache published data only as long as the integration can tolerate stale passport updates.
• Test that Draft, Active and Archived records remain excluded.
