# Resume Agent

> Resume an interrupted Agent execution — continue after HITL approval

When a tool triggers an HITL (Human-in-the-Loop) interrupt during Agent execution, the frontend collects the user's approval decision and uses this endpoint to resume execution.

Returns an **SSE streaming response**, continuing execution from the interruption point.

`user_id` is automatically extracted from the JWT Token and does not need to be passed in the body.
