Data transfer between different flow

I'm trying to bring together data from multiple processes in Node-Red into one process. So you need a way to transfer data between the different flows of Node-Red.

Hi. Welcome to the forum

To pass data between tabs on the same installation, use the link in and link out nodes.

If you want to call into a flow, on a separate tab, to grab some data and return it (like a subroutine) use the link call node.
