Hello,
Im trying to write a PHP script to check historical data of avg monthly
searches for a given keywords list. However I cannot get the credential
files to work.
// planner.php
use Google\Ads\GoogleAds\Lib\V18\GoogleAdsClientBuilder;
use Google\Ads\GoogleAds\V18\Services\
GenerateKeywordHistoricalMetricsRequest;
require 'vendor/autoload.php';
$configFilePath = 'google_ads_php.ini';
$googleAdsClient = (new GoogleAdsClientBuilder())
->fromFile($configFilePath)
->build();
$customerId = '9810123038';
try {
$keywordPlanService = $googleAdsClient->getKeywordPlanIdeaServiceClient
();
$keywords = ['test keyword', 'another keyword'];
$request = new GenerateKeywordHistoricalMetricsRequest([
'keywords' => $keywords
]);
$response = $keywordPlanService->generateKeywordHistoricalMetrics(
$request);
foreach ($response->getMetrics() as $metric) {
printf(
"Keyword: %s, Avg monthly volume: %d\n",
$metric->getText(),
$metric->getMetrics()->getAvgMonthlySearches()
);
}
} catch (Exception $e) {
printf("Error: %s\n", $e->getMessage());
}
in the same folder as code above I have 2 files:
// google_ads_php.ini
[GOOGLE_ADS]
developerToken = "cut"
jsonKeyFilePath = "E:/path/to/credentials.json"
scopes = "https://www.googleapis.com/auth/adwords";
clientId = "clientid.apps.googleusercontent.com"
clientSecret = "cut"
refreshToken = "cut"
Ive got the refreshToken from buildFullAuthorizationUri() that prompted
google login screen correctly.
and:
// credentials.json
{"web":
{"client_id":"cut",
"project_id":"cut",
"auth_uri":"https://accounts.google.com/o/oauth2/auth";,
"token_uri":"https://oauth2.googleapis.com/token";,
"auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs";,
"client_secret":"cut",
"redirect_uris":["http://localhost"]}}
No matter what I do I cannot go over:
*Fatal error*: Uncaught InvalidArgumentException: OAuth2 authentication
credentials must not be null.
Stack trace: #0
Google\Ads\GoogleAds\Lib\V18\GoogleAdsClientBuilder->validate()
Google\Ads\GoogleAds\Lib\V18\GoogleAdsClientBuilder->build()
thrown in
*google-ads-php\src\Google\Ads\GoogleAds\Lib\V18\GoogleAdsClientBuilder.php*
on line *429*
Any ideas on how to solve that? File paths are correct because I can print
those files content.
