Some automations must stop and wait for a person — approve a risky action, confirm a payload, or supply missing input. In Flowra this is human in the loop (HITL).

​
When it appears

  • A static workflow graph includes a human_wait (or equivalent approval) node.
  • An agent run interrupts and waits for a resume command (for example after a tool that requires confirmation).
While paused, inspect the execution or thread state, then resume with the required input.

​
Resume a paused workflow execution

After POST /api/v1/workflow/manager/execute/{id} returns a thread ID, if the run pauses: POST /api/v1/workflow/manager/executions/thread/{threadId}/resume Send any required input in the body (see resume schemas in the API reference). Use this for static workflow runs that wait for user input or approval.

​
Resume in the Chat / Threads API

For Graphify-style agent runs, join or continue the stream and send a command such as { "resume": { "decisions": [...] } } when the run is interrupted. See Threads and Chat run schemas in the API reference (command.resume on run input).

​
Product tips

  • In the dashboard, open the execution detail to see where the run stopped.
  • Disable triggers while you change approval steps if concurrent fires are a risk.
  • Keep public widgets on workflows that do not expose unchecked high-impact tools without approval.
