The API reference isn't available right now

This instance couldn't load its API specification. The reference returns as soon as the specification is readable again.

Back to the API reference

No such operation

This instance documents no operation under that identifier. It may have been renamed, or it may belong to a feature this installation hasn't enabled.

Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-01 06:25 UTC.

API reference Notifications

Opens a listen session for the caller's merchant and returns its signing secret, once.

POST /api/notifications/listen-sessions deprecated

Requires: Notifications.ListenSessions.Listen, merchant scope.

The secret is not recoverable afterwards: only a hash of it is stored. Losing it means opening a new session.

Example request

Every block below sends the same request. Replace {{BASE_URL}} with the address of the API you are calling and {{API_KEY}} with your own key.

The request body is a CreateListenSessionInput. See the Request body section below for its fields.

Code sample language

cURL
curl -X POST "{{BASE_URL}}/api/notifications/listen-sessions" \
  -H "api-key: {{API_KEY}}" \

  "eventTypes": [
    ""
  ]
}'

$headers = @{
    'api-key' = '{{API_KEY}}'

Parameters

Name In Type Description
suppressNulls required query boolean If true, omit properties with null values.

Request body

application/json , required

Field Type Description
eventTypes required array of string Event types to stage. Empty means every event type the caller may see, resolved once at creation and then fixed for the session's lifetime. nullable
label required string Optional human label, so an operator's list reads sensibly. nullablemax length 128
ttlMinutes required integer (int32) Requested session lifetime in minutes, renewed by poll activity. Clamped server-side; a value outside the supported range is corrected, not refused. nullable

This request body has no documented fields.

Responses

200 The session was opened. The body carries the signing secret, once.

Body: ListenSessionCreatedDto Each item has these fields.

Field Type Description
id required string (uuid) The session id, used on the poll, sample and end routes.
signingSecret required string The signing secret, shown exactly once. nullable
merchantId required string (uuid) The merchant the session is scoped to.
eventTypes required array of string The resolved event types the session stages. nullable
expiresAtUtc required string (date-time) When the session expires unless polling renews it.
ttlMinutes required integer (int32) The clamped session lifetime, in minutes, that each poll renews by.

This response has no documented body fields.

403 The caller has no merchant context, so there is no single merchant to scope a session to.

Body: Each item has these fields.

Field Type Description

This response has no body.

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. See the error-code reference in this document's description for the values `error.code` can take.

Body: RemoteServiceErrorResponse Each item has these fields.

Field Type Description
error required RemoteServiceErrorInfo

This response has no documented body fields.

429 The request was refused because a rate limit was exceeded. 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.

Body: RateLimitProblemDetails Each item has these fields.

Field Type Description
type required string The problem type identifier. Always the same value: the failure is the status code itself, so there is no sub-type for a caller to branch on. nullable
title required string A short, human-readable summary of the problem type. nullable
status required integer (int32) The HTTP status code, repeated in the body as the problem-details format defines.
detail required string A human-readable explanation of this occurrence of the problem. nullable
retryAfterSeconds required integer (int32) How long to wait before retrying, in whole seconds, carrying the same figure as the `Retry-After` header. Always at least one: a value of zero would invite an immediate retry that is certain to be rejected again.

This response has no documented body fields.

Errors

A failed request returns the platform error envelope. The error reference lists every value error.code can carry and shows the four response shapes.
