List campaign placements — Campaigns

Lists stored physical-code placement metadata. Recorded status and timestamps do not establish the current physical location of an asset. An absent campaign can return an empty list.

Retained immutable local-fixture guide, refreshed against current production catalog metadata. No examples were rerun by this author; no production action was invoked.

List campaign placements

Outcome

Lists stored physical-code placement metadata. Recorded status and timestamps do not establish the current physical location of an asset. An absent campaign can return an empty list.

After authentication and the canonical workspace grant succeed, a first workspace request may initialize the app-local identity mirror and recipient setting before the application permission check. These reads do not modify campaign-domain records or execute notifications.

Before you start

Verify the intended environment, authenticated identity and organization before discovery.
Discover the published campaigns:read application permission and inspect the credential-scoped action contract.
Discover and bind the granted canonical Campaigns workspace separately from the action input.
Fixture identifiers and simulated responses confer no live access. Replace identifiers through granted resource discovery.

Discover the target

topolo whoami --json
topolo workspaces list topolo-campaigns --json
topolo actions get app_topolo_campaigns.placements.list --json

Read app_topolo_campaigns.campaigns.list in this same authorized context and select campaigns[].id. Do not derive ids from display names.
Inspect app_topolo_campaigns.campaigns.get in the same credential and resource context before reading it.
Inspect app_topolo_campaigns.journey_events.list in the same credential and resource context before reading it.

Request

GET /api/campaigns/{id}/placements

Input fields

Field	Required	Meaning and constraints
`id`	Yes	Campaign identifier returned by campaigns.list in the same authorized organization and workspace. Type: string. minLength: 1

Verify the result

Verify campaigns.get, retain placements[].id and codeId, and inspect label, venueRef, status, placedAt and endedAt before preparing an update.

Errors and recovery

permission_denied (HTTP 403): Preserve the refusal. Verify the exact application permission and canonical workspace grant, or the organization boundary for export. Do not widen context or retry with a different resource to evade a denial.
auth_error (HTTP 401): Authenticate again in the intended environment and pinned organization, then repeat identity and resource discovery.

Authentication, input validation or resource middleware can refuse a request before these handlers. Preserve the actual refusal and request id.

Recovery boundary

These reads do not change campaign-domain records and require no domain rollback. A permission or privacy refusal is authoritative; preserve its context and request id.

Get campaign — Campaigns: Reads one non-deleted campaign in the bound organization and workspace. An absent or differently scoped campaign returns HTTP 404 campaign_not_found.
List campaign journey events — Campaigns: Lists stored journey events for the campaign, newest occurrence first. Subject and external references are stored attribution, not executed follow-ups. An absent campaign can return an empty list.

Evidence

Actual Campaigns handleRequest, permission checks, store queries and replayed SQLite migrations. Credential verification and canonical workspace grants are simulated at the Auth package boundary; egress is sealed. No deployed/provider outcome, live redemption, outbound communication or live access is demonstrated.

Reviewed immutable source: TopoloCampaigns@cacbb8b12b4e19a662cf82d03a927aef3c3a35e8, docs/action-read-records.json. Fresh production catalog was read on 2026-10-20. Its publication metadata is not proof that this source is loaded. Output examples are not widened or rewritten to force schema success; the accompanying validation record classifies exact success, refusal, no-body and structural-schema limits.

app_topolo_campaigns.campaigns.get: Read one campaign with its offer, codes, status and redemption totals.
app_topolo_campaigns.journey_events.list: List the journey events recorded against a campaign, the trail of what a recipient did.

Local input rejection example

This deliberately invalid input belongs to a pure schema check; it is never a planned or executed request. The closed action input schema must reject the extra field. It has no HTTP status or server response.

{
  "id": "campaign_docs_fixture",
  "__unsupported_field": true
}

The hidden companion labels this as ILLUSTRATIVE_LOCAL_SCHEMA_CHECK; its validation representation is not an action output.

Published output validation limits

Current published output qualification: the output schema rejects the empty-object, partial-success-marker, partial-data-object and refusal-body probes. A schema-valid success body still does not establish execution, live permission, selected context or a provider outcome.

These observations come from pure checks of the exact published schema; they are not server responses or production captures.
