How to send data to "execute workflow" node?

Questions

Hi dear friends;

I know that for reading data in “execute workflow”, data in last note will export to “start” node in sub-workflow and then I can use them from “start” node.
I want to know how can I use data from specific nose from master workflow. (For example how can I use webhook data that is not saved in last node)

That is sadly not possible. You have to make sure to add it before again with for example a merge node.
