How to receive HITL interrupt events via webhook in LangSmith Deployment?

LangSmith Product Help Deployment

Hi everyone,
I have a LangGraph assistant running on LangSmith Deployment (Langgraph Platform).
I’m triggering runs successfully from a lambda, providing webhook url and receiving regular status: success webhooks at my endpoint, but I never get the __interrupt__ (human-in-the-loop) payloads.

Is there a specific way to configure a HITL webhook for interrupt events (like email_approval) — either in the UI or via API?

Would appreciate any example or guidance — thanks!

Hi @dudiradosezki - currently we only support triggering webhooks on run success, but this does seem like a good feature request and I can add it to our roadmap, thank you for bringing it to our attention.
