Passing variable from 1 flow execution to the next
I did some research and could not find if passing a variable from 1 flow execution to the next is doable. Let me explain what I'd like to do: My flow is triggered by a scheduler, every 5 mn. First execution, Flow runs a query on an API which return an integer (say 'nbhits'), and store 'nbhits' in a variable say nbhits_var. Second execution 5mn later, Flow runs the same query on the API and obtain nbhits, compare nbhits with nbhits_var. If nbhits>nbhits_var then send notification.
Is this feasible in Flow, or do I need to store the variable somewhere else e.g. an external database? My preference would be NOT to store the variable elsewhere.
