Cannot get OAuth credentials be recognized by PHP script

[M T]

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.

Hi,

Thank you for reaching out to the Google Ads API support team.

I would recommend you refer to this guide on 'Make an API call' for the step-by-step instructions on how to make an API call using the PHP client library. This guide also has information on how to fetch a refresh token using the credentials.json file that was downloaded after you created the client ID and client secret.

I hope this helps.

Hey,
I did exactly that, but withOAuth2Credential shows as undefined:

namespace Google\Ads\GoogleAds\Examples\Planning;

    header("Content-type: text/plain; charset=utf-8");

require 'vendor/autoload.php';

use GetOpt\GetOpt;

use Google\Ads\GoogleAds\Examples\Utils\ArgumentNames;

use Google\Ads\GoogleAds\Examples\Utils\ArgumentParser;

use Google\Ads\GoogleAds\Lib\OAuth2TokenBuilder;

use Google\Ads\GoogleAds\Lib\V18\GoogleAdsClient;

use Google\Ads\GoogleAds\Lib\V18\GoogleAdsClientBuilder;

use Google\Ads\GoogleAds\Lib\V18\GoogleAdsException;

use Google\Ads\GoogleAds\Util\V18\ResourceNames;

use Google\Ads\GoogleAds\V18\Common\MonthlySearchVolume;

use Google\Ads\GoogleAds\V18\Services\GenerateKeywordHistoricalMetricsRequest;

use Google\Ads\GoogleAds\V18\Services\GenerateKeywordHistoricalMetricsResult;

use Google\ApiCore\ApiException;

$oAuth2Credential = (new OAuth2TokenBuilder())

    ->fromFile('google_ads_php.ini')

    ->build();

$googleAdsClient = (new GoogleAdsClientBuilder())

    ->fromFile('google_ads_php.ini')

    ->withOAuth2Credential($oAuth2Credential)

    ->build();

Tried updating packages, manually downloading them from github, nothing works.

Hi,

As the issue is related to the PHP client library, I would suggest you create a "New issue" with the developer who maintains the PHP client library using this link.
