Langfuse Integration

Langfuse integration API reference for the Galtea SDK

The Langfuse integration module provides drop-in replacements for Langfuse’s tracing APIs that send traces to both Langfuse and Galtea.

from galtea.integrations.langfuse import CallbackHandler
from galtea.integrations.langfuse import observe
from galtea.integrations.langfuse import start_as_current_observation

For setup instructions and usage patterns, see the Langfuse Integration overview.

APIs

Decorator API

• observe — Drop-in replacement for langfuse.observe. Wraps a function with Langfuse’s @observe and adds optional trace_id linking.

Context Manager API

• start_as_current_observation — Drop-in replacement for langfuse.Langfuse.start_as_current_observation. Creates a root observation with optional trace_id linking.

LangChain Callback API

• CallbackHandler — Drop-in replacement for langfuse.langchain.CallbackHandler. Automatically manages trace_id context around LangChain callback lifecycles.
