I´m trying to make a conection with the API of Google Adwords, after make the instalation using
Git Clone and Composer Install , then I extract the refresh token via
GetRefreshToken.php but, when I try to get the first call to the API via the file
GetCampaigns.php, it shows the next error message :
Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://adwords.google.com/api/adwords/cm/v201708/CampaignService?wsdl' : failed to load external entity "https://adwords.google.com/api/adwords/cm/v201708/CampaignService?wsdl" in C:\xampp\htdocs\google_api\googleads-php-lib\src\Google\AdsApi\Common\AdsSoapClient.php:68 Stack trace: #0 C:\xampp\htdocs\google_api\googleads-php-lib\src\Google\AdsApi\Common\AdsSoapClient.php(68): SoapClient->SoapClient('https://adwords...', Array) #1 C:\xampp\htdocs\google_api\googleads-php-lib\src\Google\AdsApi\AdWords\v201708\cm\CampaignService.php(146): Google\AdsApi\Common\AdsSoapClient->__construct('https://adwords...', Array) #2 [internal function]: Google\AdsApi\AdWords\v201708\cm\CampaignService->__construct(Array) #3 C:\xampp\htdocs\google_api\googleads-php-lib\src\Google\AdsApi\Common\Util\Reflection.php(39): ReflectionClass->newInstanceArgs(Array) #4 C:\xampp\htdocs\google_api\googleads-php-lib\src\Google\AdsApi\Common\AdsSoapClientFa in C:\xampp\htdocs\google_api\googleads-php-lib\src\Google\AdsApi\Common\AdsSoapClient.php on line 68
