I need to create a new product group. I have used below library to do that process.
https://github.com/googleads/googleads-php-lib.
I tried add Shopping campaign to create a new product group.
I don't know whether it is correct or wrong. If the method is correct,
const BUDGET_ID = 'INSERT_BUDGET_ID_HERE';
const MERCHANT_ID = 'INSERT_MERCHANT_ID_HERE';
I want to know where can i get "BUDGET Id". Otherwise please provide the sample code to create product group using google ad words API.
Note: I am new to google ad words.
