The row shape differs by kind. Discriminate on `type`. Here `type` is **single-valued** rather than repeatable; omit it to get both. `pagination.totalElements` is the sum of the two sources' own counts. This endpoint takes no `folderId`. ## OpenAPI ````yaml /api-reference/openapi.yaml get /v2/lists openapi: 3.1.0 info: title: Inflection Developer API version: 1.0.0 description: > The Inflection Developer API (`/v2`). Authenticate with a Personal Access Token (`Authorization: Bearer inf_pat_...`). **`/v2` is `/v1` plus more.** Every `/v1` endpoint is served here unchanged, so a client can pin to one version and reach the whole API. On top of those sit reads `/v1` never had: journeys, journey and email stats with a journey rollup, and the email and list collections. `/v1` remains published. **Response envelope.** Every response is wrapped: `{ "data": …, "pagination": …, "errors": [...], "meta": { "status": "SUCCESS|FAILURE", "timestamp": "…" } }`. `data` carries the payload, `pagination` appears only on paged lists, and on failures `errors` is populated with `meta.status: "FAILURE"`. **Query parameters are camelCase**: `pageNumber`, `pageSize`, `startTime`, `folderId`. The journeys, emails, lists and stats reads additionally accept the snake_case spelling of every scalar parameter (`page_number`, `folder_id`, …); the contact, activity and list-member endpoints do not. Repeatable parameters also accept a `[]` suffix (`status[]`, `tag[]`). **Asynchronous contact writes.** `POST/PATCH /v2/contacts*` are processed asynchronously: they return **200** with a `PENDING` transaction acknowledgement (not the created/updated contact). Poll `GET /v2/contacts/transactions/{transactionId}` for the per-contact result. **Status-code quirks** (documented per-operation): a missing **contact** is reported as **400** (not 404), whereas a missing **list**, **email** or **journey** is **404**. For journeys and emails that also covers a soft-deleted record and a malformed id. Nothing returns 201 or 204. **Empty results are not errors.** On the paged reads, a `tag`, `folderId` or `search` that matches nothing returns an empty page, not a 404. **Errors.** Failures use the envelope above (`errors[].{errorCode,message,detail}`). Authentication and authorization failures (401/403) are returned with an empty body. The journey stats rollup adds `RESULT_SET_TOO_LARGE` (a **400**) when a filter matches more journeys than one request may cover; narrow it rather than paging further. **Rate limiting.** Requests are metered per tenant. Exceeding the budget yields **429** (empty body) on any endpoint; the `Retry-After` header gives the seconds to wait and `X-RateLimit-Limit` the sustained per-second budget. servers: - url: https://api.inflection.io description: Production security: - PatAuth: [] tags: - name: Contacts description: Create, read, and update contacts.
