Unique ID for some collection

Question:
Hello guys so for context i have this site that I want to add user registration and I have done so using the wix members area app. Now because I want to later down the line publicly display certain information like first name, last name and because I want to later create a collection “Events Participated” where i reference users from; hence, I created a collection “User Profiles”. Essentially I want it so upon every sign up using the members app, i create a record with certain field in this collection with some unique ID that can be referenced in other collections. How do i go about creating this unique id field? how do i make so on sign up i create some record in this collection? Please bare with me as i am veryyy new to wix velo and would really appreciate any help!

Hello Ahmad, no need to create UID’s since the wix member is automatically generated. If you are creating a new collection in the content manager, every item will also have a automatically generated _id field. You can set up a webhook after a member is created to pass their information into your new collection. This will give you full control to scale and customize the fields you need in your other collection. That’s the initial direction I would do.
Wix members will also allow you to display their names without any custom code needed and will handle all of your security/auth concerns out of the box. The other collection will be the “create your own adventure” piece.
