Response
OK
Template id (22-char shortuuid). Use in /lots/templates/{id}/ paths.
Human-readable template name.
Which GS1 field the identifiers populate.
lot, serial Token format, e.g. LOT-{YYYY}{JJJ}-{####} renders as LOT-2026123-0001.
Alphabet identifier or literal characters. Defaults to GS1 AI 82.
Optional check character appended after token expansion.
none, mod10, iso7064_11_2 When the counter resets to its starting value.
never, daily, weekly, monthly, on_product_change, on_count_reached, manual How the counter is partitioned (the scope_key shape).
global, per_product, per_product_per_date_bucket, tag Counter value used after a reset (first sequence emitted).
Soft-retry budget per identifier for random-source tokens before a hard collision.
Current template version. Bumps on a format-affecting edit while in use.
Archived templates cannot generate until unarchived.
Creation timestamp (ISO-8601).
Last-modified timestamp (ISO-8601).
Optional free-text notes.
Counter value that triggers a reset when reset_condition=on_count_reached.
Reserved for row-per-version chains; null in the current in-place versioning scheme.
