5. The `line_total`*must* equal the `unit_price` × `qty`
!!! info
If you provide a value to `total_amount` as we have above, it *must* equal the sum of all the `line_total` values. Before 5.20 there was [a bug](https://lab.civicrm.orog/dev/financial/issues/73) that required the top-level `total_amount` was provided, but from 5.20 onward you can ommit this and it will be calculated automatically from the sum of the `line_items`.

Currently the data returned from `Order.create` shows only the fields from the created Contribution. However an `Order.get` API call for the ID will also include an array of `line_items` (see below for example).
