Can we get data from sandbox appstore by using app store connect api? How ? anyone can please help me ?

When I tried to fetch sales and trends data from app store connect api, it worked very well. but it shows many special characters on browser. I have implemented it in PHP. Can you say please it will generate a zip file to download or It will give a json formatted output. Why it shows special characters on browser? My Code: $api_url = 'https://api.appstoreconnect.apple.com/v1/salesReports'; $api_url .= "?filter[reportType]=SALES&filter[reportSubType]=SUMMARY&filter[frequency]=YEARLY&filter[reportDate]=2020&filter[vendorNumber]=".$vendorNum."&filter[version]=1_0"; $headers = [ 'Content-Type: application/json; charset=utf-8', 'Accept: application/a-gzip, application/json', 'Authorization: Bearer '. $token, ]; $response = callAPI('GET', $api_url, false, $headers); //$response = json_decode($response, true); echo $response;

How to get sales report data between two date range from app store connect api? This API does not allows us to provide startDate & endDate in its request call.
