So…have you looked at what is in the payload from the debug?

Look thru the results of the debug you have provided and find the part that says
payload:…
what does it say?

Payload is correct for me
payload: “text = prova”
Can you explain me ?

There are 2 messages in that debug you pasted. Look at the second payload

Just to be a bit more explicit - the second message in the debug output you’ve shared has a payload which is the response from the rpinotify api. It includes an error message telling you what is wrong with the request you’ve made.
Rather than set `msg.payload` to the String `text = prova`, try configuring the Inject node to send an Object (pick ‘JSON’ in the list of types) of `{ "text": "prova" }`. By default, the HTTP Request node will send that as `application/json` content. The API _might_ accept that. If it doesn’t, then you’ll need to set the content-type to form-urlencoded. To do that, use a Change node to set `msg.headers["content-type"]` to the String `application/x-www-form-urlencoded`

yeah!
the problem is
"To do that, use a Change node to set msg.headers["content-type"] to the String application/x-www-form-urlencoded"

OH, and another problem is that if you use the `change` node to set `msg.headers["Content-type"]` with a **Capital 'C'** , the incoming msg.payload is empty!
There goes another hour... and a good bit of my remaining hair! Shouldn't the behavior of the http nodes not be dependent on the correct case of any headers?

what is handling the request at the other end ?

That would be the `http in` node inside the same instance of node-red -- which in this case would have worked, I think, if it wasn't for the mangled request url (missing the host:port)
On the receiving side I have this:
and the sending flow's `http request` _seems_ to reference it, using this config:
If I use a relative url in the `http request` node, I get a 404 error, with this responseUrl: `http:///zippi/users` which explains the 404 not found error -- this is a separate issue I mentioned on slack.
But, while trying to describe the problem here, I'm not seeing the same behavior -- of course. So it must be related to the fact that upstream from this `http request` is another `http request` node that is muddying the wires... or at least my request headers. What is the best practice for cleaning up a msg object between requests?

The request node is like a browser - if you type /foo into a browser it won't go to [http://localhost:1880](http://localhost:1880) either...
Depends how clean you need it - a change node to delete msg.res and msg.headers may be enough. Or a function node to return a completely clean object.
Not sure re Capital C - we do send it out with whatever capitalisation you set... - but the http in node seems to flatten it to lowercase anyway so shouldn't be an issue.
Do you have a simple demo flow that shows the problem ?

That is true, when typing into the browser... but not strictly true, when you are talking about html components. Any element with `src="/foo"` is considered to be relative to the current host:port -- and any url without a leading slash is relative to the current page's url.
This behavior is built-in to many web components:
