Keep your graph and its state
Your graph stays in LangGraph, along with its state and the logic that selects the next branch.
Integrations, LangGraph
Put business rules around LangGraph actions
Keep building in LangGraph. The VeriProof LangGraph adapter checks each graph run against your rules, and the Python core SDK covers the individual steps that need their own check. Your graph keeps its state and flow.
Control the work that matters
A message sent or a record changed can have real consequences. Use a policy-controlled run when the graph needs permission to proceed.
Give business rules a place in the workflow
Check a proposed action against your VeriProof policies. The decision stays available for later review.
Act on the policy result
Continue, stop, or wait for review. Your application applies the result where it controls the action.
Connect with the LangGraph adapter
veriproof-sdk-adapter-langgraph checks a complete graph run: the input before the graph starts, and the result before your application releases it. It installs the Python core SDK, veriproof-sdk, along with it.
The adapter doesn't check each node on its own, streamed output, or graph calls made outside it. When one node sends a message, moves money, or changes a record, wrap that action with the core SDK so it gets its own check.
Your application keeps the LangGraph checkpoint, the wait for a reviewer, cancellation, and the final business outcome.

Common integration questions
LangGraph continues to run the graph, keep its state, and select the next branch. VeriProof supplies the policy result and decision history for the actions you choose to control.
Your application keeps the checkpoint, validates the signed review result through the core SDK, and directs LangGraph to the next branch. The adapter and the core SDK return the same typed results, so the handling is the same either way.
Start with nodes that change records, send messages, or call external tools. Send only the details your policy and reviewers need.
