Environment Variables¶
The LangGraph Cloud API supports specific environment variables for configuring a deployment.
LANGGRAPH_AUTH_TYPE¶
Type of authentication for the LangGraph Cloud API deployment. Valid values: langsmith, noop.
For deployments to LangGraph Cloud, this environment variable is set automatically. For local development or deployments where authentication is handled externally (e.g. self-hosted), set this environment variable to noop.
N_JOBS_PER_WORKER¶
Number of jobs per worker for the LangGraph Cloud task queue. Defaults to 10.
