URL from Webcore to Emoncms

I'm trying to to do a basic request to test that I can post on my Emoncms but, even if I've no error, nothing is log on Emoncms.
Any idea?

what do the logs show when you hit test? The logs you show are for when the piston was saved (but it has not been executed)

I've added a schedule and yes you're right, now I've a log that shows the issue. But I stll can't understand what's wrong...

have you tried putting single quotes around your string to the http request?
