  title: GrowthBook REST AnalyticsExplorations projects API
  description: "GrowthBook offers a full REST API for interacting with the application.\n\nRequest data can use either JSON or Form data encoding (with proper `Content-Type` headers). All response bodies are JSON-encoded.\n\nThe 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.\n\n## Versioning\n\nEndpoints are versioned by path prefix:\n\n- `/v1/...` — stable, widely-supported endpoints\n- `/v2/...` — updated endpoints with improved shapes (e.g. unified per-rule environment scope for feature flags)\n\nNew integrations should prefer v2 where available.\n\n## Authentication\n\nWe support both the HTTP Basic and Bearer authentication schemes for convenience.\n\nYou first need to generate a new API Key in GrowthBook. Different keys have different permissions:\n\n- **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.\n- **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`\n\nIf 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)\n\n```bash\ncurl https://api.growthbook.io/api/v1/features \\\n  -u secret_abc123DEF456:\n```\n\nIf using Bearer auth, pass the Secret Key as the token:\n\n```bash\ncurl https://api.growthbook.io/api/v1/features \\\n-H \"Authorization: Bearer secret_abc123DEF456\"\n```\n\n## Errors\n\nThe API may return the following error status codes:\n\n- **400** - Bad Request - Often due to a missing required parameter\n- **401** - Unauthorized - No valid API key provided\n- **402** - Request Failed - The parameters are valid, but the request failed\n- **403** - Forbidden - Provided API key does not have the required access\n- **404** - Not Found - Unknown API route or requested resource\n- **429** - Too Many Requests - You exceeded the rate limit of 60 requests per minute. Try again later.\n- **5XX** - Server Error - Something went wrong on GrowthBook's end (these are rare)\n\nThe response body will be a JSON object with the following properties:\n\n- **message** - Information about the error\n"
