You can see it with Edit Fields node and building an expression like: `{{ $('nodename').params }}` ![image](https://europe1.discourse-cdn.com/n8n/original/3X/9/e/9e009e60a6fcf2d97f6a15fa57ebd122b5ebbafc.png) But it’s a very rare case when you need it. ---

Thank you for the reply. If it’s super rare I don’t see the point of teaching it in course level 1 to be honest. What you mean is that it’s rare that you reference the input of an HTTP request in a different node, right? However your reply doesn’t answer the question how to get these types of inputs via GUI as described on the mentioned page of the course. Someone in the Discord mentioned that this is actually outdated. So I’ve created a [bug report on GitHub as well](https://github.com/n8n-io/n8n-docs/issues/2891). ---

> [@SamHartmannCom](#): > > What you mean is that it’s rare that you reference the input of an HTTP request in a different node, right? No, accessing another node’s output is a common scenario. but accessing the `.params` property of a node is very rare. It’s a special variable that holds the chosen options of the desired node. That information is not needed in 99% of cases. Dunno why it’s in the course. Actually, the course has been written a while ago, so it’s a question to @bartv 😁 You can check more of the special variables there: [Output of other nodes | n8n Docs](https://docs.n8n.io/code/builtin/output-other-nodes/) > [@SamHartmannCom](#): > > However, your reply doesn’t answer the question of how to get these types of inputs via GUI as described on the mentioned page of the course You can’t expand them via GUI 🙂 maybe it was possible previously, but currently, as I know, there is no way to do so. ---

Thanks again @barn4k You are right. The text courses - both - are embarrassingly outdated for such a hyped company/product from my point of view. I’ve added [several bug-reports](https://github.com/n8n-io/n8n-docs/issues) and a small fix to the GitHub repo. ---
