# Get fee by ID

Returns the **single fee** matching `id` for the practice identified by `X-Practice-Id`. The identifier is the same `id` returned when listing fees.
If no fee exists for that practice and `id`, the API responds with **404**.

    Example: 2024-06-20T14:05:22Z

  - `data.id` (string, required)
    Unique identifier for the fee.
    Example: 3fa85f64-5717-4562-b3fc-2c963f66afa6

  - `data.payment_plan_id` (string, required)
    The payment plan (fee schedule) id of the resource.
    Example: 3fa85f64-5717-4562-b3fc-2c963f66afa6

  - `data.is_multiple_pricing` (boolean, required)
    When true, all five quantity-based pricing tiers are returned. When false, only the first tier (`quantity` 1 / `*_one` fields) is returned.
    Example: true

  - `data.tiers` (array, required)
    Pricing tiers for quantities 1, 2, 3, 4, and 5 (five or more), in that order. When `is_multiple_pricing` is true, all five tiers are included; when false, only the first tier is included.

  - `data.tiers.quantity` (integer, required)
    The number of units this tier applies to. `5` means five or more.
    Example: 1

  - `data.tiers.price` (number, required)
    The price for this tier.
    Example: 55
