Hello Team,

I am using "Google Picker API" to upload and download file using picker. While uploading document, customer is getting error "Google hasn’t verified this app". I have verified domain and app as well but still facing same warning every time for each customer.

Hello harshadtrustdee,

To authenticate as an end user and access user data in your app, you need to create one or more OAuth 2.0 Client IDs. A client ID is used to identify a single app to Google's OAuth servers. If your app runs on multiple platforms, you must create a separate client ID for each platform. You can check this documentation for the steps.
