What about those two Question marked item. How do I get those?
I believe there should be a help page for each node and credentials on how to use them. I am happy to add it and make an PR on docs repo if someone can add a link to that on credentials popup and on node edit popup.
The key can be found on the top of the same page. For reference here the link: https://trello.com/app-key
There is also a link to create a token directly underneath it.
Yes, I totally agree there should be a help page. I wanted to do it for a long time but sadly never got to it. So any help there would be really appreciated! You can simply create a new page here: https://github.com/n8n-io/n8n/tree/master/docs
I can then take care of linking it in the menu and later also in the nodes itself. Thanks!
