## OpenAPI
````yaml openapi.yaml POST /v1/experiments/{id}/start
openapi: 3.1.0
info:
version: 5.1.0
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** - Unprocessable Entity - The request is valid, but a warning,
validation rule, approval requirement, or another publishing gate blocked
it. Do not assume that `ignoreWarnings` clears every 422 response.
- **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
### Publishing gates
Publish responses include a `gates` array that explains every blocker:
- `type`, `severity`, and `messages` identify the problem.
- `override` names the request-body field that can bypass it. This is
`ignoreWarnings` for warnings, `skipSchemaValidation` for schema and
invariant failures, or `skipHooks` for Custom Hook rejections. A value of
`null` means there is no request-body override.
- `requiresPermission` identifies any additional permission needed to use
the override.
- `resolution` provides an API action, method, and path when the blocker
must be resolved another way.
For example, an approval gate is cleared by approving the revision or by
using a caller with **Bypass draft approvals** access. A Config lock is
cleared through the unlock route in `resolution`.
When a successful publish bypasses a gate, the response includes
`bypassedGates`. Each entry reports the gate `type` and how it was bypassed
in `via`, which is one of `ignoreWarnings`, `skipSchemaValidation`,
`skipHooks`, `bypassApprovalPermission`, `restApiBypassesReviews`, or
`revertsBypassApproval` (reverts only). This field is omitted when no gates
were bypassed.

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: constants
x-displayName: Constants
description: >-
**Beta** — these endpoints are new and may change in
backwards-incompatible ways.
Reusable named values referenced from feature flag values as `@const:key`
and resolved into the SDK payload at build time. String constants are
interpolated via `{{ @const:key }}`; JSON (object) constants are composed
via an `$extends` array. A constant's own keys **replace** what its
`$extends` bases provide, wholesale — constants are atomic building
blocks. (Config and feature values compose as deep, targeted patches
instead.)
- name: constant-revisions
x-displayName: Constant Revisions
description: >-
**Beta** — these endpoints are new and may change in
backwards-incompatible ways.
Draft revisions for constants, including pending changes, approvals, and
lifecycle (publish, discard, revert). Pass `version: "new"` on edit
endpoints to auto-create a draft.
- name: configs
x-displayName: Configs
description: >-
**Beta** — these endpoints are new and may change in
backwards-incompatible ways.
Reusable, typed, inheritable JSON objects referenced from feature flag
values as `@config:key`. A config carries a field `schema` (with
TypeScript/JSON Schema import-export) and a lineage `parent`. Inheritance
is expressed via `parent`, never an in-value `@config:` entry. Values
layer as a **deep, targeted patch**: a child (or a config-backed feature
value) restates only the leaves it changes and inherits the rest — unlike
a constant's `$extends`, whose own keys replace wholesale. Schema fields
colliding with a published ancestor's key follow 'base wins': identical
re-declarations are stripped with a warning, differing ones are rejected.
- name: config-revisions
x-displayName: Config Revisions
description: >-
**Beta** — these endpoints are new and may change in
backwards-incompatible ways.
Draft revisions for configs, including value and schema edits, schema
import (JSON Schema / TypeScript / inferred), approvals, and lifecycle
(publish, discard, revert). Publishing a schema change cascades the "base
wins" normalization to descendant configs; a publish that removes or
retypes fields descendants still use soft-blocks with a 422 unless the
request body sets `ignoreWarnings: true`. 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: custom-hooks
x-displayName: Custom Hooks
description: >-
Sandboxed JavaScript validation hooks that run when features, configs, or
their revisions are saved or published. Throwing an Error blocks the save;
`addWarning(msg)` raises a soft warning. Hooks are scoped by projects, or
pinned to a single feature/config via `entityType`/`entityId`; a
config-scoped hook also runs for every config inheriting from it (its
whole descendant lineage). Scope can be retargeted on update (or cleared
with nulls). Requires an enterprise plan; not available on GrowthBook
Cloud.

`fallback` either keeps running (`notify`) or ships
`fallbackVariationId`. `force-ship` stops and rolls out
`fallbackVariationId`. `stop` is a hard deadline that stops with no
rollout. For `force-ship` and `stop`, the Decision Framework verdict
