Google Ads

Hard

The slow part is Google's OAuth app verification for the Google Ads scope (Google Ads docs call it restricted, others call it sensitive), plus a manual audit of about 10 business days if you need Standard's unlimited operations.

A multi-user agent that reads reports and manages campaigns at Basic access (15,000 ops/day), which needs brand verification plus Google OAuth app verification for the Google Ads scope; Standard access adds a manual audit of about 10 business days. Google Ads docs call the scope restricted; if it is reviewed as restricted, Google's FAQ estimate is 6 weeks instead.

Waiting on
Google's OAuth app verification for the Google Ads scope (3–5 business days typical for sensitive scopes, often longer), then automated Basic approval; Standard needs a manual Google compliance review.
Cost
No fees found in the docs

What you need first

  • A Google Cloud project with the Google Ads API enabled

    Since 2026-09-09 the project that generates your OAuth credentials sets your API access level; sign-up and upgrades happen on the Google Ads API Overview page.

  • An OAuth consent screen set to External and In production, with verified branding

    Brand verification is required before applying for Basic or Standard access, and Google's Ads guide says the app must be External and In production.

  • A paid (non-Free-Trial) Cloud billing account in good standing

    A known issue causes Basic access rejections for projects on the Free Trial or with a suspended or disabled billing account.

  • Google Ads test accounts for development

    Test access only works against test accounts until Explorer or higher is granted.

  • A tool that meets the Required Minimum Functionality (for Standard)

    Standard access applicants must comply with RMF and may need to give Google demo sign-in access.
