Is this possible to create a private report filtering in Data Studio embeded report - google-data-studio

Question

I created a report in DataStudio and embedded it on my website. I activated the option "anyone with the link can view" so this report will be visible to my website users.
But I need to show my website users different data depending on their user ids and more important I don't want users would be able to see other users' data so if I used URL filtering users would be able to breach and search another user id to see his data.
Does anyone have a solution for this scenario?
In Google documentation I saw an option to limit the report to users in my domain, I assume this will solve this issue, but I don't find how to restrict other domains.

Answer 1

Users are logged onto Google
If users of your website are already logged onto Google, use the Filter by email address guide from Data Studio help center. This requires you to setup FILTER BY EMAIL and then have a field in your data can be directly used as an email filter.
Users are not logged on to Google
If you want a solution where the users don't have to be logged onto Google, you will need to:
Create a Community Connector to pass the filtered data to your users. The connector should accept a short lived token as part of the config.
Create a dashboard with your connector and pass unique short-lived tokens for each user.
You should have an endpoint that returns the current user's data based on the token provided. Alternatively, the endpoint can return only the user's identify and you can query a secondary data source with a service account filtering for the user's identity.
Your connector should call your endpoint to fetch data only for the user/for the user's identity.
This official guide demonstrates how to implement this in more details.

First option is to add extra 2 fields to your data source.
User_ID
Password
For example:
Data, User_ID, Password
$10,Daniel,123
$20,Alex,456
In your dashboard, you need to create two parameters:
User_ID_Parameter
Password_Parameter
Both parameters can set the default value to null, and accepts any values.
Then create a new calculated field:
CASE
WHEN REGEXP_MATCH(User_ID,USER_ID_Parameter) AND REGEXP_MATCH(Password,Password_Parameter) THEN 1
ELSE 0
END
Then create a new filter to the chart that you want to hide:
To include the above calculated field Equal to 1
Second option is to use the Data Studio default Row Level Security
The only caveat is the users need to sign in before they can view the report.
