Use when chat message received url in an external app

Hey, I’m new to n8n. I created this chat AI agent, which works well in n8n, but I want to use the chat URL in an external app. I’m testing in an HTML page for now, but there is no response.

Did you select “Embedded Chat” In the chat trigger node?


And then follow the instructions here: @n8n/chat - npm

Yes I did. I tried with and without. I want to send and receive messages. I think the issue is in the input format, I’m sending a JSON format like: {
“input”: “Hello”
}
