The connector models the data in TaxJar into a list of tables that can be queried using standard SQL statements.
Generally, querying TaxJar tables is the same as querying a table in a relational database. Sometimes there are special cases, for example, including a certain column in the WHERE clause might be required to get data for certain columns in the table. This is typically needed for situations where a separate request must be made for each row to get certain columns. These types of situations are clearly documented at the top of the table page linked below.
