Maintain Conversation History in n8n with Claude Code Session IDs

Initial Status Query

Contextual Follow-up

Generating a Session UUID in n8n

1. Click the '+' button to add a new node.
2. Search for and select the 'Code' node.
3. Ensure the language is set to 'JavaScript' in the node settings.
4. Input a JavaScript function to generate a random UUID (Universally Unique Identifier).
5. Execute the node to generate the ID variable.

Initiating a Persistent AI Session

1. Open the configuration for the node executing the Claude Code command.
2. In the command input field, type your initial prompt (e.g., 'how many access points are up right now').
3. Append the flag `--session-id` to the end of the command string.
4. Drag and drop the UUID variable from the previous Code node into the command field after the flag.
5. Ensure there is a space between the flag and the variable.
6. Click 'Execute Node' to run the initial query.

Resuming Context in Follow-up Steps

1. Create or configure a new command node for the follow-up interaction.
2. Enter a context-dependent prompt (e.g., 'Why is one of them down?').
3. Append the `-r` (resume) flag to the command string.
4. Map the *same* UUID variable from the initial Code node after the `-r` flag.
5. Click 'Execute Node' to process the prompt using the history from the previous step.
