Integrating vault setup as a global variable

Hello,
I am trying to use vault for which values are defined already (global variables) i want to use them in my automation.How i can do it. Please help.

structure is like
a:
b:
vault:
url:
user:

vaulted variables are only different in the way they are stored.
otherwise pretty much transparent

So your question is more how to merge variables i guess?

Hi Dick,
yes,how i can merge them.
