Ideally, we'd request the minimum permissions necessary to gather your data. Unfortunately, Google does not currently provide any other way for us to get access to Google Ads data today. The only permission we can request is full access.
That being said:
- The Metrics Watch app only reads your data, and does not modify it.
- This will likely change in the future, as Google Ads improves their API.
You can find the relevant documentation from the Google Ads API here.
An alternative solution is to create a read-only user, as suggested here.
