# Ping the server

After you set up your authentication method, use "ping" once to verify that the service is up.

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

**Advice:**

-   You only need to use Ping once. If you want to periodically verify that the service is running, we recommend using 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 do run multiple Ping jobs, be sure that they run at least 5 minutes apart. If you do it in shorter periods, you may receive an error such as: "Hit Limit".
