What is the id of the option?

The ID of the option, also known as "optionRefId" is a long code that contains all the necessary information to proceed between the different methods of our Booking Flow. When you are in Search Method, if you decide a returned option to Quote, you will need to copy the Option ID and send it in the Quote Request. Once the quote is performed, you will receive a new "optionRefId" to be sent in the Booking Request.
