Marketplace Collection List - Submit Button

Hi folk,

I have the following usecase:

  1. Marketplace Collection List
  2. A single Item contains a Button for Download the resource
  3. When hitting that Button following happens:
    • Check if user is authenticated if not redirect to Login Page
    • In case it is authenticated send request to our backend service with some data attached like:
      → Marketplace Item Title
      → Marketplace Resource URL

I do not know how I can achieve the frontend part. How I can map the collection list data to that button:

  1. Form? All the forms would have the same name and the same event linked to my custom code
  2. Button w/o Form with an On Click Event and Custom Code? Also here I have tried to map the Collection Item data to my custom code w/o success.

Some Ideas?
