The Rezgo API is used by the consumer facing (front-end) booking engine. The code for the front-end booking engine has been made open source and is available for you to use in your development project. If you are using WordPress, we also have a fully functional plugin that contains all the same features as the front-end booking engine. The Open source PHP parser also contains all the same functions but requires a bit more configuration and development experience to use. You can find them at:
