For custom function webhooks, you can return the value as a dynamic variable that the agent can reference using {{variable_name}} syntax. [(2) ]()
If your n8n response is returning strings with extra quotes (e.g., "\"value\"" instead of "value") , this is typically an n8n formatting issue you'd need to resolve in your n8n workflow using expression nodes or JSON parsing before the "Respond to Webhook" node.

Would you like me to try providing a general answer about JSON parsing techniques?AI Evy
