}Beta. The
data payload is versioned by payload_version and its shape is
not yet frozen. See List Events.Overview
Returns the full body for one ledger row — the same body the matching webhook delivery carried, so you can verify or re-read a delivery you already received. Trademark-family events include field-level diffs;alert.created renders its stored versioned payload.
Requires the events:read scope.
Path Parameters
string
required
Event ID (
evt_*). A raw numeric ID returns 400 validation_error; a valid public ID of another type returns 400 id_type_mismatch.Response
Beyond the summary fields on List Events, the detail body carries:integer
The aggregate version this event was recorded at.
string[]
The fields that changed, in public trademark field names —
status, mark_text, publication_date, ir_number, or a changed child collection (owners, classifications). Fields Signa does not publish are omitted rather than renamed.object
{ [field]: { before, after } }, keyed by the same public names as changed_fields.string | null
The office-reported data date this event is from (
YYYY-MM-DD), or null when the feed reports none. Day precision, and the meaning varies by office: USPTO transaction date, WIPO gazette date, snapshot offices the crawl date. Distinct from occurred_at, which is when Signa produced the event.object[]
The portfolios the mark belonged to when the event was recorded, each
{ id, external_ref }, frozen at record time. Empty when the mark was in no portfolio. Absent on alert.created.Errors
| Status | type | When |
|---|---|---|
| 400 | validation_error / id_type_mismatch | Malformed or wrong-type event ID |
| 403 | forbidden | Missing events:read |
| 404 | not_found | Event doesn’t exist, has aged out of the 30-day window, or belongs to another org |
Code Examples
curl "https://api.signa.so/v1/events/evt_3D7rZ9" \
-H "Authorization: Bearer sig_YOUR_KEY"
const event = await signa.events.retrieve('evt_3D7rZ9');
