For a lottery operator, the buying question is practical: can a purchase, result check, payout or support case move between the intended channels without losing its meaning? This framework turns that question into an integration and acceptance brief.
Choose the channel model before the interface
List the first-release channels: staffed retail, self-service terminal, agent network, web and mobile. For each, specify products, opening hours, available actions and operating owner. Separate what must work on day one from what may follow later.
Map those decisions against the platform modules and delivery scope. A shared wallet, shared identity or cross-channel payout must be an explicit requirement, not an assumption inferred from the word omnichannel.
Define identity and wallet boundaries
Decide whether each journey uses an identified account, a ticket reference or another permitted operating model. Specify how a retail-origin ticket is recognised online, if that journey is required. Define the checks and support process for disputed ownership.
- Which balances or ticket records can the customer see in each channel?
- Which actions require identification, approval or a channel-specific restriction?
- Who can correct a linkage error, and how is the correction recorded?
- What happens when an account restriction must take effect across channels?
Write a ticket lifecycle for every channel
Use the same business event definitions where channels must agree. Do not rely on identical button labels to establish identical behaviour.
| Stage | Requirement to specify |
|---|---|
| Sale | Purchase reference, draw cut-off, payment confirmation and ticket issuance. |
| Validation | Ticket status, result source and the authority to confirm a claim. |
| Payout | Eligible payout channel, approval flow and link to the original ticket. |
| Exception | Cancellation, duplicate presentation, unavailable terminal and disputed status. |
Separate player money from agent settlement
Define the flow of cash, electronic payments, prizes and agent remuneration. Agent commission, terminal cash handling and player wallet movements are different records; finance needs a clear relationship between them.
Specify settlement periods, cut-off times, reconciliation files and dispute ownership. The lottery payment-stack guide supports the payment-provider discussion; the channel brief must also cover cash collected or prizes paid through retail, when those flows are in scope.
Make interfaces and reporting operationally usable
List each interface with its producer, consumer, identifiers, update timing and failure owner. For example, define how a terminal sale becomes visible to support and when it appears in the channel report. Use the lottery API integration guide for the wider integration contract.
- Require a traceable path from channel transaction to ticket, payment and draw result.
- Distinguish delayed reporting from missing transactions; agree the escalation for each.
- Specify views for operator finance, support and agent management, with appropriate access.
- Define offline behaviour explicitly: whether sales stop, queue or use an approved alternative, and how recovery is checked.
Roll out with a channel acceptance matrix
Use the launch-readiness checklist to connect these cases to the launch decision. Keep a record of gaps, dependencies and accountable owners instead of declaring readiness from the interface alone.
- Run a purchase, result check and permitted payout through each first-release channel.
- Demonstrate a required cross-channel journey with the same ticket and consistent status.
- Test a duplicate claim, a connectivity interruption and an account restriction in a non-production environment.
- Reconcile a completed test period across sales, prizes, payments and agent records.
- Confirm trained owners, support escalation and a controlled pause or rollback procedure.
Turn the architecture into a buying brief
Your brief should contain the channel matrix, ticket lifecycle, identity decisions, settlement responsibilities, interface inventory and acceptance evidence. Bring that brief into the operator-readiness resources and supplier discussion. Compare the delivered scope with the operating model you actually intend to run, not the longest feature list.
Discuss your retail and online requirements
Share your current channels, intended customer journeys, agent structure and first-release scope. WhiteLotto can discuss the platform fit and integration boundaries for your omnichannel project.
