How to connect it

Hi,
I’m trying to apply this to connect with my Analytics account.
But I can’t

You write
———–
In order to connect to your Google Analytics Account, you need to create a new project in the Google API Console and activate the Analytics API in “APIs & auth > APIs”.
Then, create an OAuth Client ID in “APIs & auth > Credentials”. Enter this URL for the Redirect URI field:
https://****myspecificdata****
You also have to fill the Product Name field in “APIs & auth” -> “Consent screen” — you need to select e-mail address as well.

I don’t really understand how to do that, where I can find the several option …
Do you have a more detailed document (step by step) to show that ?
Thanks
Pending to your reply.
