Payment Gateway Integration Process
Payment integration is as much an onboarding project as a technical one. Provider approval, documentation and testing often take longer than writing the code. This page sets realistic expectations for how the process runs.
- Provider selection guidance
- Parallel onboarding & build
- Edge-case testing
- Go-live monitoring
The stages
A typical payment integration moves through these stages.
- Provider selection: methods, markets, currencies and fees
- Provider onboarding: your application, KYC and merchant approval
- Technical build: deposit, withdrawal and callback flows
- Testing: success, failure, duplicate and late-callback scenarios
- Go-live with monitoring and reconciliation checks
What slows projects down
Provider onboarding is the usual bottleneck. Gambling is a high-risk merchant category, and providers perform their own due diligence. Starting provider applications early — in parallel with technical work — keeps the timeline honest.
Testing edge cases
Real payment traffic produces late callbacks, duplicate notifications and abandoned sessions. The integration is tested against these cases before go-live, not discovered through player complaints.
Frequently Asked Questions
How long does payment integration take?
The technical build is usually the smaller part; provider onboarding timelines vary by provider and your documentation. We plan both tracks in parallel.
Can you integrate a provider we already use?
Yes. If you hold an existing provider agreement, we integrate against your account and credentials.
