<b>Excluded from the per-request log and from traffic aggregation.</b> A listener polls this on
a timer for as long as a developer leaves it running: at a one-second interval that is roughly
86,000 log rows a day, which would bury the API calls the developer opened their logs page to
find, and would out-weigh a merchant's real traffic in every aggregation chart. The volume is
still visible, on `ListenSessionMetrics`; an exclusion without a counter behind it is just
a blind spot.
The exclusions are per action. Session create, sample and end on this same controller stay
captured and audited, because those are the calls that say something happened.
Signed in, you can send this request to your own sandbox merchant from the console

Too Many Requests
The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.

Not Found
No such session for this caller. A wrong id, another merchant's session, an ended session and an
expired one are deliberately indistinguishable, so an id-shaped probe learns nothing. default
The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. The error reference lists the values `error.code` can take. The request failed.
