Ga Management Api - Custom Dimensions List() - Error 403: Insufficient Permission

I'm using Management API (using PY Client Library) to get list of Custom Dimensions as described here - Custom Dimensions: list link = analytics.management().customDimensions().l

Solution 1:

I have had a similar problem, notice that listing custom dimensions can only be done using those scopes:

['https://www.googleapis.com/auth/analytics.readonly', 'https://www.googleapis.com/auth/analytics']

get() and patch() can be done using https://www.googleapis.com/auth/analytics.edit scope, I am assuming this is the one that you are using.

It is annoying as edit scope can list most of the assets such as goals but not custom dimensions and metrics.

Hope that resolves your problem
