## 2.12.2 Send receipts — Supported

Give the patron a receipt for what they have just borrowed or returned.

### What you can build

A self-service machine or a staff desk can print or show a receipt straight after checkout or checkin. Where the library system sends receipts itself, the patron can get them by email or text message instead.

### Typical flow

1. The patron borrows or returns material (2.16.1, 2.16.2).
2. A completed `Checkout` or `Checkin` returns what the receipt needs: the item, the publication, the date and time and, on a loan, the due date.
3. The client prints or shows the receipt from that response.
4. Where the provider offers the notification types `checkout_receipt` and `checkin_receipt`, the patron can choose a delivery method for them with `UpdatePatronNotificationSettings` (2.11.4), and the library system sends the receipt itself.

### What the API provides

- `publicationId` is there so the client can show or print a title. `publicationMetadata` is a fallback when the publication cannot be fetched on its own.
- `fees` lists the fees the checkout or checkin created, for example an overdue fine. An empty list means none; a missing field means the provider cannot tell.
- `checkout_receipt` and `checkin_receipt` are recommended notification types, not required ones. `GetPatronNotificationSettings` shows which types the provider has.
