# Notifications metrics

> Period-bound delivery-health aggregates over a filtered notification set: how many emails were delivered, failed, and rate-limited in the window. Requires period {from,to}. Optional filter and a single group_by axis (event_name / status / channel).

Contract:
- MCP tool `get_notifications_metrics`, registry package `mcp.id/notifications`, mount `id.platform`.
- Operation `metrics`, response envelope `metrics`.
- Flags: read only.



## OpenAPI

````yaml /api-reference/id/openapi.yaml post /api/notifications/metrics
openapi: 3.0.3
info:
  title: 'GTM API public contract: gtm.service.id'
  description: >-
    Identity, access and money: users, teams and members, API keys, OAuth
    clients and authorizations, billing products, subscriptions, transactions
    and payment methods, the credit ledger, notifications, TLS certificates,
    observability and support requests.


    GENERATED. This document is projected from the Zod MCP tool registry in
    `product/mcp/gtm.mcp` (one tool per public endpoint, 1:1). Do not edit it by
    hand; edit the tool definition and regenerate with `pnpm openapi:public`.


    Surface: the public `/api` contract of `gtm.service.id`, 77 operations.
    Internal (`/internal`) and health endpoints are deliberately absent; the
    code-faithful spec that documents those lives in
    `product/openapi/gtm.openapi.tech`.


    Conventions:

    - Auth is a bearer JWT, optionally narrowed by the `Team-SID` header.

    - Every success body is an MCP envelope: `success: true` plus one typed
    `operation` shape (`search`, `get`, `create`, `update`, `delete`, `metrics`,
    `group_by`, `action`), and a `meta` block with `trace_id` for support.

    - Every failure is the same `McpError` envelope with a code from a fixed
    16-code taxonomy, so a client maps errors once.

    - Lists page with `page_size` (0 to 500, default 50) plus an opaque forward
    `cursor`; `page_size: 0` returns counts only.

    - On `GET` and `DELETE`, object-valued query parameters (`filter`, `sort`)
    travel as JSON text and array-valued ones repeat as `name[]=value`.

    - The MCP-only `_meta` field (usage analytics) never reaches the backend and
    is not part of this contract.
