report-data

/* requestReport */
$req = $client->requestReport(
    "productAds",
    array("reportDate" => "20160916",
          "campaignType" => "sponsoredProducts",
          "metrics" => "impressions,clicks,cost,attributedConversions30dSameSKU,attributedConversions30d,attributedSales30dSameSKU,attributedSales30d"));
 
/* getReport */
$req = $client->getReport("REPORT_ID");
file_put_contents("/Users/dbrent/Downloads/report.json", $req["response"]);
 
 
Then I processed the data like so:
 
$report_json = json_decode(file_get_contents("/Users/dbrent/Downloads/report.json"), true);
$tsv = "sku\tasin\tadId\tclicks\timpressions\tattributedSales30dSameSKU\tattributedSales30d\tattributedConversions30dSameSKU\tattributedConversions30d\n";
foreach ($report_json as $rj) {
    $clicks = "";
    $impressions = "";
    $adId = $rj["adId"];
    $clicks = $rj["clicks"];
    $impressions = $rj["impressions"];
    echo "Processing {$adId}\n";
    $req = $client->getProductAd($adId);
    $json_ad = json_decode($req["response"], true);
    $sku = $json_ad["sku"];
    $asin = $json_ad["asin"];
    $tsv .= "{$sku}\t{$asin}\t{$adId}\t{$clicks}\t{$impressions}\t{$rj['attributedSales30dSameSKU']}\t{$rj['attributedSales30d']}\t{$rj['attributedConversions30dSameSKU']}\t{$rj['attributedConversions30d']}\n";
    usleep(5000);
}
file_put_contents("/Users/dbrent/Downloads/report.tsv", $tsv);
