Curl passing two Query string or arguments:
The -G argument will append the data specified in -d and --data-urlencode arguments at the end of the request URL, joining all data pieces with the & character and separating them from the URL with the ? character.

Example:
curl -vv -G -d "track=randwick" -d "race=1" https://s9iwqktpp8.execute-api.ap-southeast-2.amazonaws.com/puntwit

> GET /puntwit?track=randwick&race=1 HTTP/2
> Host: s9iwqktpp8.execute-api.ap-southeast-2.amazonaws.com
> User-Agent: curl/7.58.0
