A row is recorded only when the composite status changes, so `fromStatus` is the status it moved away from and the series has no repeats. `activeMonitors` is the set active immediately after each transition, as recorded at the time. Transitions predating this report an empty set. ## OpenAPI ````yaml /openapi-v2.json get /v2/tests/{testId}/status-history openapi: 3.1.0 info: title: Trunk API version: 2.0.0 description: >- The Trunk public API. Every endpoint is scoped to a single organization and requires a credential. ## Authentication For automation, send an API key as `Authorization: Bearer `. An organization admin creates one in the Trunk app under **Settings → Developer → API Keys**, and chooses the merge-queue permissions it holds. A key with no permissions can read merge queues but change nothing. Those permissions scope merge queue only: every key can use the Flaky Tests and Dynamic CI endpoints, including their writes, whatever permissions it holds. A short-lived first-party token in the `x-trunk-token` header is what the `trunk` CLI sends after `trunk auth login`. A GitHub Actions job can upload impacted targets with no Trunk secret: the `trunk-io/login` action exchanges the run's own GitHub credential (its OIDC token, or on a pull request from a fork its `GITHUB_TOKEN`) for a short-lived first-party token. That token is accepted only by `PUT /v2/impacted-targets`, for the run's own repository — and on a fork pull request, only for that pull request and its head sha. ## Errors Every 4xx and 5xx response is a `ErrorResponse`: `{ "error": { "code", "message" } }`. Switch on `code`, which is stable; `message` is prose and may change at any time. **An authorization denial on a read is reported as `404`, not `403`** — whether a resource exists must not leak across organizations, so a resource in another organization is indistinguishable from one that does not exist. `403 INSUFFICIENT_PERMISSIONS` means the credential is valid but is not permitted the action (or carries no organization). Every response carries an `X-Request-Id` header. Quote it in support requests. ## Rate limiting Requests are limited per organization (currently 100 requests/second). Exceeding it returns `429` with `RATE_LIMIT_EXCEEDED`; retry with backoff. Note that the limit is enforced at the edge, which does not yet wrap its `429` in the `ErrorResponse` envelope described above — treat any `429` as rate limiting regardless of body. ## Compatibility Within v2, Trunk may add: new endpoints, new **optional** response fields, new members to any enum (including new `code` values, new queue-entry states, and new providers), and new optional request parameters. **Clients must tolerate values and fields they do not recognize** rather than failing closed — a client that switches exhaustively over an enum will break when a member is added. Removals and semantic changes require a new major version. ## Provider support Merge queues, verification runs and checks are **GitHub-only** today; `Check.provider` has a single member for that reason. Impacted-target uploads additionally require a `github.com` repository named `owner/repo`. The `Provider` enum lists values the repository index can store, not surfaces that are fully supported. ## Not yet available A pull request's numeric **position** in its queue, and any wait estimate, are not exposed, and list responses are not ordered by queue position. `GET /v2/merge-queues/{id}/order` returns the order the engine will consider pull requests in, but an array index there is not a wait: use a pending entry's `directlyAhead` rather than counting. This API delivers no events of its own — poll it, or subscribe to [Merge Queue's webhooks](https://docs.trunk.io/merge-queue/webhooks). `Idempotency-Key` is not yet honored, so a mutation that times out must be reconciled by reading the resource back rather than blindly retried. contact: name: Trunk Support url: https://docs.trunk.io servers: - url: https://api.trunk.io description: Production security: - apiKey: [] - trunkToken: [] tags: - name: mergeQueues x-group: Merge Queues - name: pullRequests x-group: Pull Requests - name: mergeQueueVerificationRuns x-group: Verification Runs - name: impactedTargets x-group: Impacted Targets - name: repositories x-group: Repositories - name: dynamicCi x-group: Dynamic CI - name: ciJobs x-group: CI Jobs - name: ciWorkflowRuns x-group: CI Workflow Runs - name: ciFailureClusters x-group: CI Failure Clusters - name: testCollections x-group: Test Collections - name: tests x-group: Tests paths: /v2/tests/{testId}/status-history: get: tags: - tests summary: List a test's status transitions description: >- Returns the test's status transitions, newest first.
