Writeback functionality - Looker

[pjaiswal]

We wanted to understand how can we achieve writeback functionality(making edits in the report and sending the data back to the backend) in Looker. On doing some google search, we came across Data Actions. This can be used in conjunction with Cloud functions which can accept the json payload, parse it and send the data to Biq query.

However, on using the above approach Cloud function has to allow all traffic and unauthenticated requests, hence making it unsecure. Is there any other way to achieve this in a secured manner.
