google analytics api need exact date, hour and minute - google-analytics

Question

Im experimenting with the google reports api (v4), im using the goalCompletionsAll metric, and is bringing the info that i need, im passing as parameters ga:medium, ga:date, ga:hour however when i pass the ga:minute parameter as request it throws me the following error: "Selected dimensions and metrics cannot be queried together." I understand that the metrics have their own set of dimensions, but i found this weird, since when i use the query explorer i add all this dimensions and it returns the correct info, but as soon as i put in the code, it displays the error...
Here i attach my code to see if someone can point me into the right direction regarding this.
<?php
require_once 'google-api-php-client/src/Google/autoload.php';
session_start();
$client = new Google_Client();
$client->setAuthConfigFile('xxxxx');
$client->addScope(Google_Service_Analytics::ANALYTICS_READONLY);
// If the user has already authorized this app then get an access token
// else redirect to ask the user to authorize access to Google Analytics.
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
// Set the access token on the client.
$client->setAccessToken($_SESSION['access_token']);
// Create an authorized analytics service object.
$analytics = new Google_Service_AnalyticsReporting($client);
// Call the Analytics Reporting API V4.
$response = getReport($analytics);
// Print the response.
printResults($response);
} else {
$redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . '/api/oauth2callback.php';
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
}
function getReport(&$analytics) {
// Replace with your view ID. E.g., XXXX.
$VIEW_ID = "xxxxxxxx";
// Create the DateRange object.
$dateRange = new Google_Service_AnalyticsReporting_DateRange();
$dateRange->setStartDate("2016-01-01");
$dateRange->setEndDate("today");
// Create the Metrics object.
$sessions = new Google_Service_AnalyticsReporting_Metric();

return $analytics->reports->batchGet( $body );
}
function printResults(&$reports) {
for ( $reportIndex = 0; $reportIndex < count( $reports ); $reportIndex++ ) {
$report = $reports[ $reportIndex ];
$header = $report->getColumnHeader();
$dimensionHeaders = $header->getDimensions();
$metricHeaders = $header->getMetricHeader()->getMetricHeaderEntries();

for ( $rowIndex = 0; $rowIndex < count($rows); $rowIndex++) {

$metrics = $row->getMetrics();
for ($i = 0; $i < count($dimensionHeaders) && $i < count($dimensions); $i++) {
print($dimensionHeaders[$i] . ": " . $dimensions[$i] . "\n");
}
echo "<br>";
for ($j = 0; $j < count( $metricHeaders ) && $j < count( $metrics ); $j++) {
$entry = $metricHeaders[$j];
$values = $metrics[$j];
//print("Tipo de metrica: " . $entry->getType() . "\n" );
for ( $valueIndex = 0; $valueIndex < count( $values->getValues() ); $valueIndex++ ) {

//print($entry->getName() . ": " . $value . "<br>");
}
}
}
}

Thanks in advance.

The issue you are seeing is that in the query explorer you are querying for ga:goalCompletionsAll and the V4 API you are querying for ga:gaolStartsAll which happens to be incompatible with ga:avgPageLoadTime:
See the Dimensions and Metrics Explorer for details of which dimensions are incompatible with others.
Remove the ga:avgPageLoadTime and you should be able to get the information you need.
TLDR: your V4 API request has different metrics than the Query Explorer Request.
