|Mandatory | Setup Avalara Credentials | The best practice is to enhance the UI for easy entry of Avalara credentials including: -   Client ID Token -   Secret Token -   Avalara end point URL |
|Mandatory | Test Authentication Connection - Heath Service (PING) | -   One for authentication /AUTH -   another for service availability /PING |
|Suggested | Enable/Disable Service Utilization | In this case, the user can enable or disable the AvaTax BR service at any time. The flag will indicate that the service is operational. |
|Mandatory | Comprehensive Logging | Given that all transactions are based on request/response JSON, the connector should provide logs of these transactions for troubleshooting, if necessary. Partners can define the time necessary to keep those data on the system. |
|Mandatory | Set the timeout to API calls | Set a timeout to API call, as recommended by best practices. |
|Mandatory | Security Communication Protocol – HTTPS/SLL | The platform (ERP´s, middleware’s, e-commerce, etc.) that will be the API calls should be prepared to support TLS 1.2. Previous versions will be discontinued and are not recommended. |
