Respond to Chat node#

Use the Respond to Chat node in correspondence with the Chat Trigger node to send a response into the chat and optionally wait for a response from the user. This allows you to have multiple chat interactions within a single execution and enables human-in-the-loop use cases in the chat.

Chat Trigger node

The Respond to Chat node requires a Chat Trigger node to be present in the workflow, with the Response Mode set to 'Using Response Nodes'.

Node parameters#

Message#

The message to send to the chat.

Wait for User Reply#

Set whether the workflow execution should wait for a response from the user (enabled) or continue immediately after sending the message (disabled).

Node options#

Add Memory Input Connection#

Choose whether you want to commit the messages from the Respond to Chat node to a connected memory. Using a shared memory between an agent or chain root node and the Respond to Chat node attaches the same session key to these messages and lets you capture the full message history.

Limit Wait Time#

When you enable Wait for User Reply, this option decides whether the workflow automatically resumes execution after a specific limit (enabled) or not (disabled).
