Hello  
When I use the terminal to create a such command 🙂  
`ngrok http https://127.0.0.1:8081`, wich is a command to create a tunnelto expose a port of my machine to the web, with ngrok, then the terminal is cleared and some datas are displayed dynamycally, like this 🙂

```auto
ngrok by @inconshreveable (Ctrl+C to quit)
                                                                                
Session Status online

                              0 0 0.00 0.00 0.00 0.00

```

This status window willbe displayed as long as I dont do a CTRL-C command.

If I try to send the same command lin via an 'exec' node, I just get a reply with the PID, no matter wich option I select in the exec node, I just get this PID value.  
How can I do to get the content of the return window wich is displayed in the terminal?

The goal of my question is to be able to intercept the line 🙂  
`Forwarding https://12345678.ngrok.io`  
Is this possible?

Connect a debug node to the bottom output of the exec node. And run the exec node in spawn mode.

Did you consider using [ngrok API](https://ngrok.com/docs#client-api) to read the tunnel data ? You just need an `http request node` configured as below:

Yes, using the API gives all the wanted result. Very good solution  
Thanks a lot
