Hello, I am new to AvaTax REST API. I have installed the RestClient.net4.5 and I am able to connect to the AvaTaxClient and use the TransactionBuilder to submit a transaction and return the tax on it within C#. However, because we program in Visual Basic and C#, I'd like to use Json. I was wondering if you could direct me to examples on how to dynmically build the Json request to send to your json api. I am not sure if I need to build my own Classes to hold all data needed or is there already something built. All I can find is examples of what the passed json file should look like and not how to build the file and pass it to your api. Any assistance would be appreciated.
