register now on a sandbox if the provider supports that option for realistic trials.
## Quick Checklist (operational ready-state)
– [ ] Sandbox with full schema and sample payloads
– [ ] HMAC/mTLS configured and rotating keys in place
– [ ] Idempotent ingestion and transaction hashing implemented
– [ ] Queue + worker architecture for reprocessing
– [ ] Daily reconciliation job and monitoring alerts
– [ ] Bankroll rules engine (units, stop-loss, VIP limits) tested
– [ ] KYC & withdrawal gating integrated with payout flows
This checklist prepares you to run with real players and ties back to the bank/FX and provider mappings we discussed earlier.
## Common mistakes and how to avoid them
Hold on — these are the gotchas that cause 70% of tickets:
1. Not normalising currency at transaction time — avoid by recording the FX rate used and storing both original and ledger amounts.
2. Relying on synchronous webhook processing — use queues to avoid lost events.
3. Ignoring idempotency — log request hashes and reject duplicates.
4. Mixing test and production keys — separate environments and automation pipelines eliminate accidents.
5. Poor bonus-game filtering — build an eligibility matrix to block ineligible games from WR calculations.
Avoid these mistakes and you’ll cut disputes dramatically, which leads into the Mini-FAQ below.
## Mini-FAQ (3–5 concise questions)
Q: How fast must reconciliation run?
A: Nightly for settlement, but real-time checks (alerts) for >AUD 1,000 wins or anomalous session spikes — next we’ll explain thresholds.
Q: What’s idempotency in this context?
A: It means processing inbound events such that re-delivered or duplicate events do not change the ledger twice; implement via request-hash + stored ids.
Q: Can I use an aggregator and still enforce my bankroll rules?
A: Yes — run the aggregator’s events through your transform layer and apply your own risk & bonus rules before committing ledger writes.
Q: What thresholds should trigger manual review?
A: Typically any single event >2% of a player’s lifetime deposits or wins >AUD 5,000, plus any reconciliation variance >0.1% of round volume.
## Small examples / mini-cases
Example 1 (hypothetical): A player with AUD 300 balance places a AUD 30 spin flagged as high volatility. Your volatility tag reduces their allowed max bet to 5% of balance; the spin is allowed and recorded with round_id mapping, preventing overdrafts and keeping the ledger sane. The next paragraph will explain how this ties to auto-risk rules.
Example 2 (realistic): Nightly reconcile shows provider A reports net -AUD 12,345 while your ledger shows -AUD 12,567. The variance of AUD 222 triggers recovery: replay the ingestion queue for the last 24 hours, identify two duplicate provider callbacks and retract a credit — the variance disappears and a ticket is closed.
## Implementation tools and vendors (short notes)
– Aggregators: speed to market, consider API mapping service.
– Message queue: Kafka/Redis for resilience.
– DB: append-only ledger (Postgres with event store or specialized ledger DB).
– Monitoring: build alerts around reconciliation variances and KYC stalls.
Choosing the right stack depends on volume; the next paragraph ties to governance and live ops.
If you want to experiment with a live demo environment or to see how a polish UX handles deposits and withdrawals in practice, try a sandbox flow or register now where supported to exercise the complete user journey before full launch.
## Responsible gaming & regulatory notes (AU-focused)
18+ only. In Australia, operators must follow AML/KYC rules, respect state-based licensing nuances, and implement self-exclusion and deposit limits at player request. Integrate RG tools (deposit caps, session timers, reality checks) directly into the bankroll engine so limits are enforced pre-bet rather than retroactively. Next we close with governance and sources.
