}Bulk import lots
Upload a file to create or update batch/lot records (GS1 AI 10) in bulk. Required columns: gtin (also barcode / upc / ean) and lot_identifier (also lot / lot_number / batch / batch_number). Optional columns: production_date, expiration_date (also expiry_date / use_by), best_before_date, quantity, unit_of_measure (a GS1 / UN/ECE Rec 20 code such as EA or KGM), harvest_date, harvest_end_date, resolver_enabled. Dates are YYYY-MM-DD.
Each row’s GTIN must already be a product in the authenticated organization’s catalog — a lot import never creates products, so a GTIN you do not own is reported as a row error. Re-importing is idempotent: a row for an existing lot updates it, a blank cell leaves the stored value unchanged rather than clearing it, and an unchanged row is counted as skipped. Once a lot is referenced by a Critical Tracking Event its identifier and harvest key data elements are locked (FSMA 204 / 21 CFR 1.1320) and an import that changes them is rejected per row rather than silently rewriting traceability history.
Accepts CSV, TSV and XLSX — the uploaded filename’s extension selects the parser, so a tab-separated file must be named .tsv (a .csv name is parsed with a comma delimiter and will fail with a missing-column error rather than misparse silently). Text uploads must be UTF-8. Maximum upload size is 10 MiB; maximum 10,000 data rows per upload. Excel stores every cell as a number unless the column is formatted as Text, which strips leading zeros from identifiers — format identifier columns as Text. The endpoint returns 200 with a per-row error report even on partial success — only request-level failures (auth, file type, file size, no brand membership) produce 4xx responses.

}Authorizations
Body
Data file to import. One of .csv, .tsv, .xlsx.
Response
OK
Outcome of a single upload to any of the POST /import/* endpoints.
Shared by the product, lot and serial imports so one response shape
covers all three. The four counters (created / updated /
skipped / error_count) sum to total_rows for any successful
request. The endpoint returns 200 even when individual rows fail —
per-row failures are reported in errors rather than aborting the
whole upload. A non-empty errors list is therefore expected on
partial success and is not itself an error condition.
Total number of data rows processed (excluding the header row).
x >= 0Number of new records created from the upload.
x >= 0Number of existing records updated. Matched on GTIN for a product import, on (GTIN, lot_identifier) for a lot, and on (GTIN, serial) for a serial.
x >= 0Number of rows that wrote nothing: a row whose values already match the stored record, or a row that failed validation (those also appear in errors).
x >= 0Number of rows that failed validation. Equals the length of errors.
x >= 0Per-row validation failures. Empty when every row imported cleanly.
