GrowthBook REST API (1.0.0)

Download OpenAPI specification:Download

GrowthBook offers a full REST API for interacting with the GrowthBook application. This is currently in beta as we add more authenticated API routes and features.

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

Authentication

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

You first need to generate a new Secret Key in GrowthBook by going to Settings -> API Keys.

If using HTTP Basic auth, pass the Secret Key as the username and leave the password blank:

curl https://api.growthbook.io/api/v1 \
  -u secret_abc123DEF456:
# The ":" at the end stops curl from asking for a password

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

curl https://api.growthbook.io/api/v1 \
-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
  • 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
