# Update a single fact metric



## OpenAPI

````yaml openapi.yaml POST /v1/fact-metrics/{id}
openapi: 3.1.0
info:
  version: 4.4.0
  title: GrowthBook REST API
  description: >
    GrowthBook offers a full REST API for interacting with the application.


    Request data can use either JSON or Form data encoding (with proper
    `Content-Type` headers). All response bodies are JSON-encoded.


    The API base URL for GrowthBook Cloud is `https://api.growthbook.io/api`.
    For self-hosted deployments, it is the same as your API_HOST environment
    variable (defaults to `http://localhost:3100/api`). The rest of these docs
    will assume you are using GrowthBook Cloud.


    ## Versioning


    Endpoints are versioned by path prefix:


    - `/v1/...` — stable, widely-supported endpoints

    - `/v2/...` — updated endpoints with improved shapes (e.g. unified per-rule
    environment scope for feature flags)


    New integrations should prefer v2 where available.


    ## Authentication


    We support both the HTTP Basic and Bearer authentication schemes for
    convenience.


    You first need to generate a new API Key in GrowthBook. Different keys have
    different permissions:


    - **Personal Access Tokens**: These are sensitive and provide the same level
    of access as the user has to an organization. These can be created by going
    to `Personal Access Tokens` under the your user menu.

    - **Secret Keys**: These are sensitive and provide the level of access for
    the role, which currently is either `admin` or `readonly`. Only Admins with
    the `manageApiKeys` permission can manage Secret Keys on behalf of an
    organization. These can be created by going to `Settings -> API Keys`


    If using HTTP Basic auth, pass the Secret Key as the username and leave the
    password blank (when using curl, add `:` at the end of the secret to
    indicate an empty password)


    ```bash

    curl https://api.growthbook.io/api/v1/features \
      -u secret_abc123DEF456:
    ```


    If using Bearer auth, pass the Secret Key as the token:


    ```bash

    curl https://api.growthbook.io/api/v1/features \

    -H "Authorization: Bearer secret_abc123DEF456"

    ```


    ## Errors


    The API may return the following error status codes:


    - **400** - Bad Request - Often due to a missing required parameter

    - **401** - Unauthorized - No valid API key provided

    - **402** - Request Failed - The parameters are valid, but the request
    failed

    - **403** - Forbidden - Provided API key does not have the required access

    - **404** - Not Found - Unknown API route or requested resource

    - **422** - Soft Warning - The request failed, but can be re-submitted with
    `?ignoreWarnings=true` to proceed anyway.

    - **429** - Too Many Requests - You exceeded the rate limit of 60 requests
    per minute. Try again later.

    - **5XX** - Server Error - Something went wrong on GrowthBook's end (these
    are rare)


    The response body will be a JSON object with the following properties:


    - **message** - Information about the error

    description: >-
      GrowthBook comes with one environment by default (production), but you can
      add as many as you need. When used with feature flags, you can
      enable/disable feature flags on a per-environment basis.

      Rules are returned as a unified top-level array; each rule carries
      `allEnvironments` / `environments` scope fields instead of being bucketed
      by environment.

      **These are v1 endpoints.** New integrations should use the v2 Feature
      Flags endpoints, which expose a unified per-rule environment scope instead
      of per-environment rule arrays.

    x-displayName: Ramp Schedules
    description: >-
      Multi-step rollout schedules that gradually increase feature rule traffic

      timers, approval gates, and hold conditions. Monitored steps are backed by
      a live analysis experiment that can automatically hold, roll back, or
      advance the ramp based on guardrail and signal metric health.

      Most callers can interact with these endpoints via shorthand actions
      (`/items/add`, `/items/remove`, single-field PUTs) instead of authoring
      JSON Patch ops directly. Pass `version: "new"` on edit endpoints to
      auto-create a draft.

      Coordinated multi-entity publishing: publish a set of revisions across
      Feature Flags, Saved Groups, configs, and constants as one all-or-nothing
      operation, validated against the combined end-state instead of each
      in-between state. Requires the `releases` commercial feature.
  - name: organizations
