+- Update `<SIGNOZ-INGESTION-TOKEN>` with the ingestion token provided by SigNoz
+- Update `ingest.{region}.signoz.cloud:443` with the ingestion endpoint of your region. Refer to the table below for the same.

+| ------ | -------------------------- |

 This runs the gin application at port `8090`. Try accessing API at `http://localhost:8090/books`
 
 Below are the apis available to play around. The API calls will generate telemetry data which will be sent to SigNoz which can be viewed at `<IP of SigNoz backend>:3000`
