Ping the server

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

Run the Health API 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 instead of pinging multiple times. See the Ping API 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".
