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

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.
- name: features-v2
x-displayName: Feature Flags
description: >-
Control your feature flags programatically.
Rules are returned as a unified top-level array; each rule carries
`allEnvironments` / `environments` scope fields instead of being bucketed
by environment.
- name: feature-revisions-v2
x-displayName: Feature Revisions
description: >-
Draft revisions for feature flags, including rules, scheduling, and
approval workflows.
Revision `rules` is a flat array with per-rule scope fields.

x-displayName: Feature Flags (legacy)

**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.

Draft revisions for feature flags, including rules, scheduling, and

Revisions endpoints.
- name: ramp-schedules
x-displayName: Ramp Schedules
description: >-
Multi-step rollout schedules that gradually increase feature rule traffic
over time, with optional real-time monitoring. Each step supports interval
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.

x-displayName: Saved Group Revisions
description: >-
Draft revisions for saved groups, including pending changes, approvals,
and lifecycle (publish, discard, revert).
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.
- name: releases
x-displayName: Releases
description: >-
**Beta** — these endpoints are new and may change in
backwards-incompatible ways.
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

Organizations are used for multi-org deployments where different teams can
