hello everyone

I figured out how to save a "flow"-wide variable using "change"-node.  
somehow I can't directly use this variable inside a "http request node"  
I always need to use another "change" node to save the variable from "flow.variable" -\> "msg.variable".

so.. how is it possible to use a flow-wide variable directly inside my http request Node?

my URL looks like this right now:  
https://{{variable}}/!run cmd test/cmd3 option 2

Have you tried `https://{{flow.variable}}/!run`?

Was that in the URL field of the http request node?

No. You need to use a change node as you originally said.

Ah. Never mind. Wasn't sure if it was a supported pattern.

Easy enough to solve with a change node or function node.
