The AvaTax ODBC Driver is a powerful tool that allows you to connect with live data from AvaTax, directly from any applications that support ODBC connectivity.

Access AvaTax data like you would a database - read, write, and update AvaTax Accounts, Customers, TaxCodes, Transactions, etc. through a standard ODBC Driver interface.

Analyze Avalara AvaTax Data in R


Create data visualizations and use high-performance statistical functions to analyze Avalara AvaTax data in Microsoft R Open.

Access Avalara AvaTax data with pure R script and standard SQL. You can use the CData ODBC Driver for Avalara AvaTax and the RODBC package to work with remote Avalara AvaTax data in R. By using the CData Driver, you are leveraging a driver written for industry-proven standards to access your data in the popular, open-source R language. This article shows how to use the driver to execute SQL queries to Avalara AvaTax data and visualize Avalara AvaTax data in R.

Install R

You can complement the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open (MRO).

Connect to Avalara AvaTax as an ODBC Data Source

Information for connecting to Avalara AvaTax follows, along with different instructions for configuring a DSN in Windows and Linux environments.

The primary method for performing basic authentication is to provide your login credentials, as follows:

  • User: Set this to your username.
  • Password: Set this to your password.

Optionally, if you are making use of a sandbox environment, set the following:

  • UseSandbox: Set this to true if you are authenticating with a sandbox account.

Authenticating Using Account Number and License Key

Alternatively, you can authenticate using your account number and license key. Connect to data using the following:

  • AccountId: Set this to your Account Id. The Account Id is listed in the upper right hand corner of the admin console.
  • LicenseKey: Set this to your Avalara Avatax license key. You can generate a license key by logging into Avalara Avatax as an account administrator and navigating to Settings -> Reset License Key.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Linux

If you are installing the CData ODBC Driver for Avalara AvaTax in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData AvalaraAvatax Source] Driver = CData ODBC Driver for Avalara AvaTax Description = My Description User = MyUser Password = MyPassword

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Load the RODBC Package

To use the driver, download the RODBC package. In RStudio, click Tools -> Install Packages and enter RODBC in the Packages box.

After installing the RODBC package, the following line loads the package:

library(RODBC)

Note: This article uses RODBC version 1.3-12. Using Microsoft R Open, you can test with the same version, using the checkpoint capabilities of Microsoft's MRAN repository. The checkpoint command enables you to install packages from a snapshot of the CRAN repository, hosted on the MRAN repository. The snapshot taken Jan. 1, 2016 contains version 1.3-12.

library(checkpoint) checkpoint("2016-01-01")

Connect to Avalara AvaTax Data as an ODBC Data Source

You can connect to a DSN in R with the following line:

conn <- odbcConnect("CData AvalaraAvatax Source")

Schema Discovery

The driver models Avalara AvaTax APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:

sqlTables(conn)

Execute SQL Queries

Use the sqlQuery function to execute any SQL query supported by the Avalara AvaTax API.

transactions <- sqlQuery(conn, "SELECT Id, TotalTax FROM Transactions WHERE Code = '051349'", believeNRows=FALSE, rows_at_time=1)

You can view the results in a data viewer window with the following command:

View(transactions)

Plot Avalara AvaTax Data

You can now analyze Avalara AvaTax data with any of the data visualization packages available in the CRAN repository. You can create simple bar plots with the built-in bar plot function:

par(las=2,ps=10,mar=c(5,15,4,2)) barplot(transactions$TotalTax, main="Avalara AvaTax Transactions", names.arg = transactions$Id, horiz=TRUE)
