**Topic type: Concept**

:::hint{type="warning"}
**Purpose**: Legacy Ticketing Fraud API overview, differences, and hashing requirements. 

**Audience**: API integrators and client developers. 

**Applies to**: Legacy Ticketing clients implementing via API.

**Does not apply to**: Universal APIs, any other industry, or ticketing clients who opt for a non-API integration.

::::

The Universal Ticketing API extends the Universal Fraud API shared transaction model with event, venue, and ticket information.

Ticketing transactions combine a shared transaction foundation with event-specific structures that describe what is being purchased and when it will be used.

## Ticketing Extension Model

The Universal Ticketing API adds:

- Event Information
- Ticket Information
- Agency Information
- Insurance Information
- Activity Information

## What Makes Ticketing Different

Ticketing commonly relies on:

- **Event identity and timing** (event ID, type, name, start time)
- **Venue context** (venue identifiers and related address references)
- **Seat/ticket details** (section, row, number of seats, contiguous seat blocks)

These fields provide important context about what is being purchased and when it will be used.

## Hashing Requirements

The Ticketing API follows the platform hashing rules. Fields designated as hash-required must be hashed before submission, including:

- `giftCardNumber`
- `hashedPassword`

See: **[Hashing Requirements](docId\:yuGHwVL8eOn7vCgSwPcd3)** (Constraint) and **[Accertify Hash Algorithm](docId\:rKIK1Lb6EUUWsz3sxPCe-)** (Reference).
