to synchronize database with wix blog users and possible?

Is it possible to have every account created in the wix blog or wix forum automatically create a new item in the database?
and make this item editable through the user inputs, only by the user when connected?

I’ve created a project, and I need every new user created using the wix blog to create a new “item” in the database with his Id and that only he can edit this “item”.

Hi.

Please check-out wix-users: Page Not Found - Velo API Reference - Wix.com
You can also set the relevant collection (database) permission for Update the collection to Site Member Author .
CMS: Collection Permissions Overview | Help Center | Wix.com
