Is it possible work with REZGO and include it on IFrame on page of my web sites?
I don't use the wordpress but I need similar solution without create a specific plugin for cms.
Thank you for your question.
Yes, you could use Rezgo in an iframe, as long as your able to do it on a page with a secure certificate enabled (https), otherwise you'll receive a security warning through your browser.
Another thing to keep in mind is you would want to customize the Rezgo template to remove the header and footer, so that they don't interfere with your existing site.
If you're looking for a bit more freedom with customization, I can also direct you to our open source parser if your web server is running PHP: https://www.rezgo.com/rezgo-open-source-booking-engine/
