Hello Costantin,
Welcome to
Google Ads API v0_1. You can use the
CustomerService to get the details of a specific
Customer but I am afraid, getting all the accounts which a user has access to, is not currently available via Google Ads API v0_1. As this API gradually rolls out, it will reach full parity with the current API. You can find the full list of services available in Google Ads API v0_1 from
here. Please let me know if you have any further questions.
Regards,
Sai Teja, AdWords API Team.
