Get your license key

This article applies to:AvaTax

A license key establishes an ongoing connection between your business application and AvaTax. However, the specific requirements for connecting depend on your business application. Some applications need just a username and a password, while others need a username, a password, an account number, and a license key. If you have both a production and a sandbox account, you need a license key for each account.

Before you begin

If someone else in your company is connecting your business application to AvaTax, make sure they have administrator permissions for the business application and AvaTax. To assign permissions in AvaTax, see add a user and set permissions.

You must be an account administrator in AvaTax to get a new license key.


  1. Go to Settings > License and API Keys.
  2. Select Generate License Key. A warning displays.
    If this is the first time you're setting up AvaTax, you can ignore the warning.
    A warning icon

    Here's why you see the warning...

    There is one license key for all business applications associated with your account. When you use a license key to connect a business application to AvaTax, generating a new license key breaks the connection to all applications. To restore the connection, enter the new license key in the AvaTax settings for each business application.

  3. Select Yes, Generate a License Key.
    Avalara emails the license key and account information to AvaTax account administrators.
  4. Download, print, copy and paste, or write down your license key so you have it for future reference.
    For example, you may need your license key if you need to update or add other business applications. For security reasons, we do not record license keys.
