The product type is unique; it outputs items line by line. To verify the correctness of the product, you can configure product validation. The line-by-line product, before being issued, will be sent to your server.
IMPORTANT: Set a limit on the number of items (lines) at a time in a single order to no more than 20; otherwise, verification may take too much time and the order will be canceled.
To set this up, create an API in the product card and specify the link to your handler
To indicate that the item is working (valid), the response must be passed as an array with key success and value true
