# Build

Learn how to meet the requirements and request access to the AvaTax Brazil sandbox environment.

Avalara has two environments for AvaTax Brazil: Sandbox and Production. Each environment is separate, and each has its own credentials. If you have a Sandbox account, you cannot use that account to log onto Production and vice versa. For developer partners in Brazil, we only release the Sandbox environment for testing.

Avalara Portal Sandbox URL: [https://portal.sandbox.avalarabrasil.com.br/Login](https://portal.sandbox.avalarabrasil.com.br/Login)

## Prerequisites

Before you request a sandbox environment, complete these steps:

* Sign the DSP contract.

* Complete the kickoff call.

## Requesting access

After you complete the prerequisites, send an email to the Brazilian Partner Launch Team at [dg-partnerlaunch@avalara.com](mailto:dg-partnerlaunch@avalara.com) to request sandbox access.

The Avalara Portal Sandbox URL is [https://portal.sandbox.avalarabrasil.com.br/Login](https://portal.sandbox.avalarabrasil.com.br/Login).
