Thoughts and lessons on client selection, burnout, pricing, and modernising legacy accounts, from someone who's run a Google Ads for years.
Google Ads API:- does every client account have to authorise your access?
Published February 2024. Last updated July 2026.
A reader asked me about authorising Google Ads API access to their clients' accounts. (Edited for clarity.)
I'm trying to build a service that will run some Google Ads queries on data from multiple client Google Ads accounts.
I'd love to be able to do this without having to get explicit front-end authorization from every user...
..If I have to I'll obviously create a little service that follows the OAuth2 web app / web server flow. But I'm hoping there's another, slightly less inconvenient method.
If all the client accounts are under your manager account (MCC) you won't need to have each of them authorise your access individually.
If you need to access client accounts outside your manager account you'll have to send each of them through the OAuth flow and you probably have to meet the required minimum functionality.
