# Unidy Web SDK — Tickets

List, filter, paginate and export a user's tickets with <u-ticketable-list>. Templates are plain HTML — the SDK stamps one copy per ticket and fills in <ticketable-value> placeholders, so you keep full control over markup and styling. The same list also powers peer-to-peer ticket transfers.

## Setup

Every example below assumes the SDK is loaded and configured once per page. The
import map lets the headless examples use the bare `@unidy.io/sdk` specifier —
the same import a bundler/npm setup uses; drop the import map if you install the
package instead.

```html
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@unidy.io/sdk@1.11.0/dist/sdk/sdk.css">
<script type="importmap">
  { "imports": { "@unidy.io/sdk": "https://cdn.jsdelivr.net/npm/@unidy.io/sdk@1.11.0/dist/sdk/index.esm.js" } }
</script>
<script type="module" src="https://cdn.jsdelivr.net/npm/@unidy.io/sdk@1.11.0/dist/sdk/sdk.esm.js"></script>

<u-config
  base-url="https://demo.unidy.de"
  api-key="your-api-key"
  locale="en"
  check-signed-in="true"></u-config>
```

## Ticket cards

A card layout driven by a <template> element. ticketable-value reads any field from the ticket — including nested metadata with fallback defaults — while ticketable-conditional and unidy-attr let the markup react to the data.

- **<template> rendering** — one card stamped per ticket, your markup
- **Nested metadata** — name="metadata.category" with default values
- **Conditional content** — VIP badge and wallet export only when the data says so
- **Export** — PDF download and Apple Wallet (pkpass)

## Table view with pagination and filtering

The target attribute renders rows into an existing element (here: a tbody), which makes tables easy. Pagination is provided by u-pagination-button/-page, and changing the filter attribute makes the list re-fetch — no custom data plumbing.

- **target rendering** — rows go into your own table structure
- **Pagination** — prev/next buttons and page indicator components
- **Live filtering** — set the filter attribute; the SDK re-fetches
- **Skeleton loading** — skeleton-all-text renders placeholders while loading

```html
<u-signed-in>
  <div class="mb-3 flex items-center justify-end">
    <select id="state-filter" class="rounded-lg border border-border bg-white px-3 py-2 text-sm">

## Transfer a ticket

Drop a u-ticket-transfer-form into a ticket <template> and u-ticketable-list stamps each ticket's id onto it — no wiring. The user types a recipient email and the SDK creates a pending transfer offer.

- **u-ticket-transfer-form** — email input + submit, styled via *-class-name
- **Auto ticket-id** — the ticket list stamps the id when nested
- **Inline feedback** — error-class-name / success-class-name outputs

```html
<u-signed-in>
  <!-- A u-ticket-transfer-form nested inside a ticket template needs no

## Incoming & outgoing transfers

u-ticket-transfer-list renders pending offers per direction with its own <transfer-value> template. u-ticket-transfer-action stamps the transfer token automatically, so accept/decline/cancel buttons need no data plumbing.

- **direction="incoming|outgoing"** — one component, two views
- **<transfer-value>** — ticket.title, sender_email, expires_at, …
- **accept / decline / cancel** — u-ticket-transfer-action with auto token

## Create test tickets through the Admin API

This optional demo-only control sends the signed-in user's short-lived SDK token to a same-origin server route. The route validates that token, derives the user id and creates the ticket with server-only Admin API credentials.

- **Authenticated user only** — the user id is derived from the SDK token
- **Server-side credentials** — client id and secret never reach the browser
- **Create and clean up** — add a test ticket and delete it again
