An Item can be a service/good that you as a merchant wish to sell to a customer. You can predefine an Item on your Razorpay Dashboard or via API, so you can quickly call them out anytime.
When an item is created, it will appear on the list of items in the Dashboard.
If your business requires you to create custom items, you can create many pre-defined item template at the ready so you can use later as a line item.
The Items API allows you create an item and perform other operation corresponding to that item.
Once an item is created, it will appear on the list of created item and also in the drop-down menu
at the time of invoice creation. You can also edit the details of a created customer by going to the
list of customers and clicking on edit under Actions.
