Yes, you can use it, although it is not necessary to have a PWA (GlobiFlow) account in order for REIvolution to work.

We recommend to discuss with us before installing any flow by your own, because we need to avoid the risk of creating Infinite Loops.

In case you don't want to bother with setting up flows in PWA, submit a Request on your dedicated Support Workspace and we'll take care of it for you.
