Funnel's Cloud Storage connector lets you export your Funnel data to a GCS bucket of your choice. This guide will cover what you need to do in your Google Console in order for Funnel to be able to export data there.
Step 1 - Create bucket
Log in to your Google Console at https://console.cloud.google.com/storage/browser and create a Bucket. You will need to decide on a globally unique "Bucket name".
Step 2 - Set bucket permissions
Enter your bucket and hit "Permissions" in the top panel.
Click "Add Member" and add firstname.lastname@example.org with the role Storage Object Admin
Step 3 - Setup an export in your Funnel account
Having completed the two steps above you can now configure your Funnel export to send data to the bucket defined above. Do this from within your Funnel account.
