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 permissions it holds. A key with no permissions can read merge queues but change nothing in them. Each write's description names the permission it needs, if any. Permissions cover merge queues and test-result uploads, including the quarantine lookups a CI run makes before it uploads; any key can call the other Flaky Tests and Dynamic CI endpoints, including their writes. A short-lived token in the `x-trunk-token` header is what Trunk's own tools send, such as the `trunk` CLI after `trunk auth login`. Your own integrations should use an API key. 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 Errors from the API are an `ErrorResponse`: `{ "error": { "code", "message" } }`. Switch on `code`, which is stable; `message` is prose and may change at any time. Some responses don't have this shape. Trunk's edge answers `401`, `403` for some credential problems (including a request with no credential), `429`, and gateway errors such as `503` before the request reaches the API. The API itself answers `413` for a body over 512 KB and `504` for a request that runs past its time limit (usually 5 seconds), both as plain text. Read `error.code` only when the body is JSON with an `error` object, and otherwise branch on the status code. **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 from the API carries an `X-Request-Id` header; edge responses may not. Quote it in support requests. ## Rate limiting Most requests share one limit per organization (currently 100 requests per second), across every API key, user, and CLI session in it. Some requests have limits of their own and don't count toward it: `GET` requests on paths that start with `/v2/pull-requests`, `/v2/ci-jobs`, `/v2/ci-workflow-runs`, or `/v2/ci-failure-clusters` (5 per second per API key or user); the merge queue metrics endpoints (5 per second per organization); impacted-target uploads from a GitHub Actions login (10 per second per repository, and separately for its fork pull requests); test-result uploads (1000 per second per organization) and quarantine lookups (250 per second per organization). Exceeding a limit returns `429`; retry with backoff. The limit is enforced at the edge, which does not yet wrap its `429` in the `ErrorResponse` envelope or send `Retry-After`, so 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. `PUT /v2/impacted-targets` accepts GitHub and GitLab repositories. A GitHub Actions login (the `trunk-io/login` action, or `trunk auth login --github-actions`) uploads only for its own GitHub repository. 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 is 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, and `GET /v2/pull-requests/{id}/queue-entry-estimate` for when it is expected to merge (on queues that serve estimates). 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 - name: testUploads x-group: Test Uploads - name: detectionEvents x-group: Detection Events 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.

Every error this API itself returns has this shape, except a `413` for a body over 512 KB and a `504` for a request that runs past its time limit, which are plain text. Responses from Trunk's edge, such as a `401`, a `403` for a missing credential, a `429` or a `503`, can arrive before the request reaches the API and may not have it, so read `error.code` only when the body is JSON with an `error` object.

An organization admin creates one in the Trunk app under **Settings → Developer → API Keys** and chooses the permissions it holds. A key with none can read merge queues but change nothing in them.
