# `LatticeStripe.BalanceTransaction.FeeDetail`
[🔗](https://github.com/szTheory/lattice_stripe/blob/v2.2.2/lib/lattice_stripe/balance_transaction/fee_detail.ex#L1)

A single fee line on a Stripe `BalanceTransaction`.

Reconciliation code typically filters by `type` to extract platform fees:

    application_fees =
      Enum.filter(bt.fee_details, &(&1.type == "application_fee"))

Stripe's known `type` enum values include `"application_fee"`,
`"stripe_fee"`, `"payment_method_passthrough_fee"`, `"tax"`, and
`"withheld_tax"`. The field stays typed as `String.t()` to remain
forward-compatible with new fee categories.

# `t`

```elixir
@type t() :: %LatticeStripe.BalanceTransaction.FeeDetail{
  amount: integer() | nil,
  application: String.t() | nil,
  currency: String.t() | nil,
  description: String.t() | nil,
  extra: map(),
  type: String.t() | nil
}
```
