For an overview on OwnerRez Widgets, widget setup, etc. look at the Setting up widgets for inquiries, bookings and availability.
Note: this guide is oriented around the setup of widgets for a couple of properties. If you've got many properties and want a parameterized setup that is possible but a bit more complex. Contact us and we'll walk you through that process.
These steps assume you've already created a page where you want to embed OwnerRez widgets.
