How to get "clientCustomerId" from Adwrods API in PHP with OAuth? - google-ads-api

Question

I am developing a Google Adwords app. I tried using the API libraries available in PHP. I found, I need "clientCustomerId" in "adsapi_php.ini". I don't see anyway to get this "clientCustomerId" using API with OAuth. Am I trying something wrong?

Answer 1

This really depends on your application design.
My setup is using a top-level manager account that has access to all the client accounts.
clientCustomerID is set to that manager id.
With that, you can grab a list of your clients using the ManagedCustomerService->get() method provided by the PHP library. You can look at the example code here:
https://github.com/googleads/googleads-php-lib/blob/master/examples/AdWords/v201710/AccountManagement/GetAccountHierarchy.php
That repo is now depreciated. As of Oct 2018 you should use this documentation: https://github.com/googleads/googleads-php-lib/blob/master/examples/AdWords/v201802/AccountManagement/GetAccountHierarchy.php

Answer 2

Try CustomerService
CustomerService provides information about your accounts. It has a
getCustomers() method that takes no arguments and returns a list of
Customer objects containing fields such as customerId, currencyCode,
and dateTimeZone. CustomerService
