API Versioning

This API uses date-based versioning. Each version is identified by a release date and slug, e.g., 2026-01-01.nova.

Specifying a Version

Include the version in the request header:

Featurebase-Version: 2026-01-01.nova

Or set a default version for your organization in the dashboard settings.

Version Compatibility

  • Newer versions may add new fields to responses (always backwards-compatible)
  • Breaking changes (removed/renamed fields, changed behavior) only occur in new versions
  • Your integration will continue to work as long as you pin to a specific version

Authentication

All API requests require authentication via API key.

Include in headers:

Authorization: Bearer <api-key>

Create and manage your API keys in the Featurebase dashboard.

Error Handling

The API uses conventional HTTP response codes to indicate success or failure:

  • 2xx - Success
  • 4xx - Client errors (bad request, unauthorized, not found, etc.)
  • 5xx - Server errors (internal error)

Error Response Format

All errors follow a consistent format:

{
  "error": {
    "type": "invalid_request_error",
    "code": "resource_not_found",
    "message": "Post not found",
    "param": "id",
    "status": 404
  }
}
