Access Adwords billing info through API in python
I am putting together some statistics for my company which include the cost per day for each user that registers. My current method is to login to adwords, download the billing information (.csv file) and load the billing information into python to do my calculation.
I know a python API exist for AdWords but I cannot seem to find a way to get the billing information for a specific day. I am not concerned with the the allowed budget for day, just the amount spent. Is this possible? Any help would be greatly appreciated. Thank you in advance.
