Returns events staged after the cursor, oldest first, and renews the session.

GET /api/notifications/listen-sessions/{id}/events deprecated

Requires: Notifications.ListenSessions.Listen, merchant scope.

Requires API key scope: webhooks ()

<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.

Parameters

Name In Type Description

id required

path

string (uuid)

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

CursorUtc required

query

string (date-time)

The cursor from the previous poll, or `null` to start at the oldest buffered event. The server re-reads a short window before this instant, so the client must dedupe.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

MaxResultCount required

query

integer (int32)

Batch size. Clamped server-side.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

suppressNulls required

query

boolean

If true, omit properties with null values.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

Request body

application/json , required

Field	Type	Description

This request body has no documented fields.

Responses

200 Events after the cursor, oldest first. May be empty.

Body: ListenSessionEventsDto ListenSessionEventsDto Each item has these fields.

Field Type Description

events required

array of ListenSessionEventDto array of ListenSessionEventDto

Events after the cursor, oldest first. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

Fields of each ListenSessionEventDto:

Field Type Description

id required

string (uuid)

The staged-event id. The client's dedupe key across the cursor's overlap window.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

stagedAtUtc required

string (date-time)

When the event was staged. The first half of the cursor.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

eventId required

string

The platform event id, forwarded as `X-WinkPG-Event-Id`. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

eventType required

string

Canonical event type. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

deliveryId required

string (uuid)

The per-staged-event delivery id, forwarded as `X-WinkPG-Delivery-Id`.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

isSample required

boolean

Whether this event was staged by a sample request rather than a live occurrence. When true, the forward to the local target carries `X-WinkPG-Sample: true`, the same marker a sample sent to a saved endpoint carries. The body is identical either way.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

payload required

string

The webhook body, verbatim. Forwarded to the local target byte for byte: re-serializing it client-side would change the bytes the signature covers and break verification. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

This body has no documented fields.

nextCursorUtc required

string (date-time)

The cursor to send on the next poll: the staging instant of the last event returned, or the cursor the caller sent when nothing was returned. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

agedOutGap required

boolean

Set when the caller's cursor predates the oldest event still buffered, meaning events expired before they were read.

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

oldestAvailableUtc required

string (date-time)

The staging instant of the oldest event still buffered, when there is a gap. nullable

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

404 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.

429 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.
