The 30-Day iGaming Integration Checklist: From Contract to Live Games
An iGaming integration checklist is the difference between a launch that lands on schedule and one that drifts for a quarter. The work is not mysterious, but it is unforgiving of missing prerequisites, untested edge cases and late certification. This is a phased, 30-day plan that takes a signed provider contract through to live games — assuming the prerequisites are genuinely in place and the compliance scope is confirmed up front.
How to use this iGaming integration checklist
Treat the four weeks as workstreams rather than a stopwatch. The sequence matters more than the calendar: you cannot meaningfully test wallet transactions before authentication and game launch work, and you cannot pass compliance sign-off before QA has produced evidence against the build you intend to launch. The 30-day framing is a realistic target for a standard casino content integration once accounts, specs and sandbox access are ready on day zero. Complex platforms, multiple jurisdictions or bespoke wallet logic will take longer, and the certification path in particular runs on the regulator’s and laboratory’s clock, not yours.
One principle governs the whole plan: build against the specification, not against assumptions. A versioned, machine-readable API description removes an enormous amount of avoidable back-and-forth, and the OpenAPI Specification is the common way to document exactly what each endpoint expects and returns before a line of integration code is written.
Week 0 — prerequisites: accounts, keys, specs and sandbox
Week 1 cannot start until day zero is closed. Confirm the commercial and technical prerequisites before scheduling anything: signed agreement and entity details, registered operator and provider identifiers, named technical contacts on both sides, environment URLs, and credentials for a sandbox or staging environment. Obtain the integration specification, the API description, the game list, and the launch/return URL contract. Agree the wallet model you are implementing — this is the decision covered in seamless wallet vs transfer wallet — because it determines every subsequent endpoint.
Where the provider supplies an RGS, confirm how the game client is delivered and how the operator platform is expected to reach it. The plain-language what is an RGS? is a useful alignment document for the project team, and it clarifies the boundary between game logic and player account management. Finally, agree the scope of the integration in writing: which games, which currencies, which languages and which markets. That last item is the one that most often turns a 30-day plan into an open-ended project.
Week 1 — API/SDK integration and authentication
Week 1 is about standing up the connection and authenticating it correctly. Implement the launch flow end to end in the sandbox: create a session, launch a game, and prove that the provider can identify the operator and player unambiguously. Authentication should be signature-based or token-based, with separate credentials per environment and secrets never exposed client-side. If you are using a delegated authorisation model, follow an established framework rather than inventing one.
Build the smallest possible vertical slice first: one game, one currency, one player, one round. Get a game to open and return the player to the correct lobby URL before worrying about the full catalog. This is also the week to validate the launch payload against the specification — the identifiers that map a player, session, game and round across two systems are the backbone of every later transaction and reconciliation, so getting them right early saves days later.
If the provider offers an SDK, use it for the boilerplate and retain visibility into what it does on the wire. SDKs accelerate the happy path; they do not remove the need to understand the wallet contract underneath. Where the integration touches an existing platform, confirm early whether any adapters or middleware are in scope, because those can add dependencies outside your direct control.
Week 2 — wallet, transactions and session handling
Week 2 is the financial core. Implement balance, debit, credit and rollback (or the equivalent of the wallet model you chose), and make every one of them idempotent. A duplicate callback must confirm the state that already exists, not move money a second time. Define and implement the retry contract for timeouts and server errors, and decide explicitly what happens to an interrupted round: which system holds the state, how it is settled, and how a correction is recorded without erasing the original trail.
Test the failure paths deliberately, not just the happy path. Fire duplicate callbacks, introduce timeouts, and force late or out-of-order events. Verify that an insufficient-funds response is handled cleanly and that a rollback reverses exactly the transaction it references. Every one of these behaviors is normal in production and catastrophic if it is first encountered there. The operational routines that keep them healthy after launch are described in from bug to fix: live game monitoring.
Session handling deserves specific attention because it sits where player experience and integrity meet. Confirm how sessions expire, how a returning player reconnects, and how the wallet reflects an interrupted session. If you are running a unified balance, prove that limits and self-exclusion apply account-wide and cannot be bypassed by starting a new session.
Week 3 — backoffice, reporting, currencies and languages
With the money paths working, Week 3 connects the operational layer. Integrate the backoffice so that operations can see game performance, player activity and transaction history, and so that finance can reconcile provider data against the operator ledger. Confirm that reports are complete and accurate for the build you are testing, because reporting is usually part of the evidence regulators and auditors expect. The metrics worth watching are set out in backoffice analytics and KPIs.
Then work through currencies and languages. Verify rounding and display for each supported currency, including how winnings and stakes are presented, and test the languages you have committed to with real strings rather than placeholders. Confirm that the game catalog, game names and any help content localise correctly. If the integration needs to slot into a broader content strategy, the trade-offs between aggregated and exclusive content are covered in aggregation versus proprietary game content, and our portfolio of crash, instant-win and multiplayer games is one example of a catalog built to slot into that layer.
This is also the week to agree the change-management approach. Ask how provider updates that affect regulated behavior will be communicated and whether they require re-certification. Deciding that process before launch is far cheaper than reconstructing it after a live incident.
Week 4 — QA, load testing, compliance sign-off and go-live
Week 4 is about proving the system, not adding features. Run functional QA across the full game list and the scenarios that matter: launch, stake, win, loss, void, rollback, session interruption, limit enforcement and jurisdiction rules. Then load-test the wallet round-trip specifically, because on a seamless model every round depends on it responding under peak concurrency. Confirm the behavior of the platform when a dependency is slow or unavailable, and rehearse the rollback decision.
In parallel, close the compliance evidence. Independent integration testing is increasingly mandated by iGaming jurisdictions to confirm that games and products function correctly once hosted on the operator’s platform, and eCOGRA’s integration testing service describes the approach: scrutinising interfaces and interactions, simulating both success and error cases, and reporting defects before they reach production. Note that integration testing is distinct from platform certification, which covers functionality, security, account management and regulatory compliance across the platform; eCOGRA’s platform certification scope is a useful checklist of what that involves.
What regulators require varies by market, and the obligation often falls jointly on the operator and the game supplier. Ontario’s Internet Gaming Go-Live Compliance Guide is a clear worked example: it requires a Technology Compliance Confirmation before go-live, an independently audited Control Activity Matrix, and certification of games, RNGs and critical system components by a registered independent testing laboratory, with recertification when modifications affect integrity, fairness or security. The exact obligations for your markets should be confirmed with the relevant authority — see the Malta Gaming Authority and the UK Gambling Commission’s remote gambling and software technical standards as starting points.
Only when QA evidence, load-test results and compliance sign-off all point at the same build should you schedule go-live. A short hypercare window after launch, with the provider’s technical contacts on standby, is standard practice for a reason.
Common integration pitfalls — and how to avoid them
The same handful of mistakes cause most delays. Missing or stale prerequisites top the list: a sandbox without credentials, a spec that does not match the live environment, or a wallet-model decision deferred until Week 2. The second is testing only the happy path, which leaves idempotency, rollbacks and interrupted rounds to fail in production. The third is treating certification as a final tick-box rather than a parallel workstream, so a compliant build sits waiting on an approval that should have been started weeks earlier. The fourth is scope drift — quietly adding games, currencies or markets that were not part of the agreed integration and were never tested.
The antidote is unglamorous: a written scope, a versioned API contract, a defined wallet model, a test plan that deliberately exercises failure, and a certification workstream running alongside engineering from Week 0. Teams that do this consistently go live on a predictable schedule; teams that do not rediscover the same pitfalls one integration at a time.

Post-launch: monitoring, optimization and next markets
Go-live is a milestone, not the finish line. Keep monitoring the wallet round-trip, error rates, game availability and settlement accuracy, and reconcile provider reports against your ledger on a regular cadence. Use the first weeks of live data to confirm that game performance and player behavior match expectations, and to decide what to add next. Then approach the next market deliberately: confirm the licensing and technical requirements before committing, and treat any market-specific configuration as a certified change rather than a runtime tweak. The regulatory context for expansion is covered in iGaming licensing across Malta, Curaçao, Bulgaria and Africa.
If you can run the same integration playbook for the next provider, you have not just launched games — you have built a repeatable capability. That is the real output of a disciplined integration.
Frequently asked questions
How long does an iGaming integration actually take?
A standard casino content integration can be completed in around 30 days when prerequisites, sandbox access and the wallet model are ready on day zero. Real duration depends on platform complexity, bespoke wallet logic, the number of markets, and — critically — how long certification takes in those markets. Treat timelines as estimates until scope and prerequisites are fixed.
Do you provide a sandbox?
Yes. Integration begins against a sandbox or staging environment with test credentials, a game list and the API specification, so the launch flow and wallet contract can be built and exercised before production. Ask for the sandbox and the integration documentation together, so the team can start with a complete picture.
What is needed for certification?
It depends on the market, but the common elements are a documented, certified build; correct RNG and game behavior; complete and accurate transaction logging; account-management and responsible-gaming controls; and independent testing by an approved laboratory. Regulators publish their own technical standards and go-live processes, and responsibilities are often shared between the operator and the game supplier, so confirm the exact scope early.
