system_prematch

Goal: Place a system selection (size 2 over 3 UF legs) as customer_system and receive accepted.

Use Selection.newSystemSelectionBuilder().setSize(2).setSelections(leg1, leg2, leg3). The first nested event must be sr:match:15050881.

How to build the request (Java SDK)

1

Configure the ticket context

Use the same TicketContext as single_accepted, but set the EndCustomer to customer_system.

2

Create one bet with one top-level system selection

Nest three UF legs with decimal odds. The first leg event must be sr:match:15050881.

3

Set a cash stake and send the ticket

Use a cash stake, then call sendTicket.

endCustomer / endCustomer.id are optional in the Ticket 3.0 schema but mandatory for this sandbox scenario (routing). Ignored by sandbox means the field is not used for routing and not used when building the reply (schema-only for the WebSocket / Ticket 3.0 envelope).

Common mistakes

Mistake	Result
Using accumulator builder	Routes to accumulator scenario (different customer)
First leg not sandbox match	Route mismatch
Wrong customer	Fallback
