Implementation:DataExpert io Data engineer handbook Statsig Initialize
Overview
Statsig Initialize is a Wrapper Doc implementation that documents the use of the external Statsig Python SDK to initialize the experimentation service at server startup. This is the concrete realization of the Principle:DataExpert_io_Data_engineer_handbook_AB_Test_SDK_Initialization principle.
Type
Wrapper Doc (external Statsig SDK)
Source
server.py:L8-9
Code
API_KEY = os.environ.get('STATSIG_API_KEY')
statsig.initialize(API_KEY)
Signature
statsig.initialize(api_key: str) -> None
Import
from statsig import statsig
Inputs and Outputs
| Direction | Name | Type | Description |
|---|---|---|---|
| Input | STATSIG_API_KEY | str (environment variable) | The secret server-side API key for the Statsig project, loaded from the STATSIG_API_KEY environment variable via os.environ.get()
|
| Output | Initialized Statsig SDK | module-level singleton | The Statsig SDK is initialized as a module-level singleton. After this call, all subsequent calls to statsig.get_experiment() and statsig.log_event() operate against this initialized instance.
|
Behavior
- The
os.environ.get('STATSIG_API_KEY')call retrieves the API key from the server's environment variables statsig.initialize(API_KEY)authenticates with the Statsig service and downloads experiment configurations- This call is made once at the module level (application startup), not per-request
- If the API key is missing or invalid, the SDK will fail to initialize and experiment calls will not function correctly
