# Ping the server

Verify that AvaTax Brazil and related services are available after you set up authentication.

After you set up your authentication method, run a ping to verify that the service is available.

-   Run the [Health API](https://api-gateway.sandbox.avalarabrasil.com.br/portal/health) to verify the portal status: https://api-gateway.sandbox.avalarabrasil.com.br/portal/health

-   Run the [OAuth API](https://api-gateway.sandbox.avalarabrasil.com.br/oauth/health) to verify the OAuth status: https://api-gateway.sandbox.avalarabrasil.com.br/oauth/health

-   Run the [AvaTax Brazil API](https://avataxbr.sandbox.avalarabrasil.com.br/v3/ping) to verify AvaTax Brazil status: https://avataxbr.sandbox.avalarabrasil.com.br/v3/ping

Tip

-   Use ping only once to verify that the service is running. To monitor status over time, use a webhook and subscribe to [status.avalara.com](http://status.avalara.com/) instead of pinging multiple times. See the [Ping API](https://developer.avalara.com/api-reference/avatax/rest/v2/methods/Utilities/Ping/) for more details.
-   If you run multiple ping jobs, make sure that they run at least 5 minutes apart. If you run them more frequently, you may receive an error such as "Hit Limit."
