}Get brand signal
Retrieve one signal for a product the authenticated brand member’s organization owns and has claimed. A signal on an unowned or unclaimed product, or one that does not exist, reads as 404 (no existence oracle).

}Authorizations
Path Parameters
Public short-UUID id of the signal.
22^[23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz]{22}$Response
OK
A signal as a brand member sees it (ownership + claim scoped).
Same code-not-label contract as :class:SignalOut. contact_email is
present only when the consumer consented and a verified address is still
attached (C-3310 consent + verification gate); otherwise it is null. Internal
consumer-account details beyond the consented contact email are never exposed.
Public short-UUID identifier of the signal.
22^[23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz]{22}$GTIN of the product this signal is about (the product's GTIN-14 string).
Consumer-picked category as a stable code (e.g. quality_issue). Never a translated label.
Freeform feedback text the consumer wrote (may be empty for voice-only signals).
True when a voice capture session backs this signal.
Whether the consumer opted in to be contacted about this feedback.
True when the text-hygiene heuristic flagged this signal's content (profanity/abuse). A flag is advisory — the signal is shown regardless; it never blocks submission. Use it to triage.
ISO-8601 timestamp the signal was submitted.
Batch/lot identifier (GS1 AI 10) carried from the scan, or null.
Serialized-unit context carried from the scan, or null.
Optional consumer-declared sentiment code (positive / neutral / negative), or null.
The consumer's verified contact email — present ONLY when contact_consent is true AND a verified address is still attached. Null in every other case (no consent, or the address was removed / lost verification). Use it in your own email; Closient does not relay replies.
Stable code describing why the signal was flagged (e.g. profanity), or null when not flagged. A code, never a translated label.
profanity
