Searching if item exists in database through API request (HTTP module)

Hello makres, Here the API documentation anchor link to the request I’m working on : MV Kaze API fork

  • What I want to do : Creating new Item in the collection :white_check_mark: It works, I know how to do it
  • Problem : I would like to check in the Collection if the Item exists before creating it

How to avoid creating duplicate item through API calls?

NB : In my case, Collection is my customer database, and Item is a customer

GET List request (I don’t know if it’s the right request to reach my goal)

Getting 100 items by default
