Hi @onurbolaca, I am afraid n8n does not offer a truly global data store you could write to from your workflows. We do have variables, but these aren’t meant to be updated from within your workflow.
So you’d typically want to use an external storage option here, like a database which allows writing and reading from any workflow.
If both triggers live in the same workflow you could alternatively consider using static data as described here in our docs. This is somewhat tricky though, because it requires code and won’t work for manual executions.
