Starting in May 2026, agents can support asynchronous workflows. Asynchronous flows continue running beyond the previous two-minute limit while still returning a response to the agent after execution completes. This feature is available only in environments running on the new infrastructure.
Enable asynchronous responses
To allow a flow to continue running beyond two minutes and respond asynchronously to the agent:
Open your agent flow and ensure it uses the When an agent calls the flow trigger.
Select the Respond to the agent action on the canvas. The action configuration pane opens.
Select Settings.
Turn on Asynchronous response.
Save or publish the flow.
This setting allows long-running flows to continue beyond the normal two-minute limit and return a response once they finish. If the user sends another message before the flow completes, the flow runs to completion, but the agent responds only to the user's latest request.
Enable immediate response behavior
If your environment supports asynchronous response and you want immediate response behavior, remove the Respond to the agent action from the flow. The agent then responds immediately after it successfully triggers the flow.
Environments without feature support
If your environment doesn't support asynchronous response, the agent might receive a "flow completed" response immediately while the flow continues to run in the background.
