I'm creating an endpoint that looks something like
POST '../v1/container/{container-id}/items/bulk-create'
This endpoint should get a list of items data and create them under that container. It's done syncly, i.e all items should be created before the user gets the response (as opposed to async job), and all items should be created or failed (no part creation). I wonder what should be the response of success - should it be 200 or 201?
