A: Hey, kamil!

GetResponse might have an integration on their side, so you'd have to ask them. If they don't, we're in the planning phase of building an API that will allow tons of apps to integrate with TidyCal directly.

Our rough ETA on this is early March (which also includes the Zapier app, which is reliant on API endpoints), although there are a lot of things we still have to scope out so that ETA is very loose and subject to change. We'll do our best to get it done ASAP on our side.
