Hi Webte,
Thank you for reaching out. In order to access the API you have to use the developer token. However, it’s not necessary to apply for one and in some cases you won’t be granted one either. So my suggestion is to contact your advertising agency or MCC account holder to ask for the use of the existing developer token. Otherwise, you could apply to upgrade your token to Basic access level.
Thanks and regards,
Xiaoming, Google Ads API Team
