Can I use my credentials in both Sandbox and Production environments?

No, you can’t. Each environment is separate, and each has its own credentials. If you have a Sandbox account, you cannot use that account to log on to Production; and vice versa.

When you receive credentials for AvaTax, it’s important to note which account the credentials are tied to (whether Sandbox or Production). We keep Sandbox and Production credentials separate to help you test your software in Sandbox without the risk of accidentally affecting production data.

If you don’t have access to the Sandbox environment, reach out to your account admin to add you as a user. More information about adding users is available in this article.
