In the first part, we covered the key criteria for choosing a payment gateway for online casinos: licenses, geography, fees, and KYC/AML requirements. Now let’s move on to practice — we’ll review the best providers on the market, real integration cases, and trends that will define the future of payment systems in iGaming.
Top Payment Gateway Providers for iGaming

For Regional Operators
Pay4Fun — specializing in the Brazilian market with PIX support. Leader in Latin America with deep integration of local banks.
Payneteasy — focus on CIS countries and Eastern Europe. Support for Russian and Ukrainian bank cards, e-wallets.

Pagsmile — another strong player in Latin America, covering Brazil, Mexico, Chile, and Peru.
emerchantpay — a universal solution with good coverage of Europe, Asia, and alternative payment methods.
Choosing a regional provider is justified if more than 70% of your audience is concentrated in a specific geographic region. Local gateways usually show higher approval rates and offer better conditions for local payment methods.
Real Integration Cases
Case 1: European Operator Focused on Scandinavia
The operator chose Trustly as the main provider due to Open Banking dominance in the region. Results: 94% approval rate, average deposit amount increased by 28% (thanks to instant crediting), chargeback rate — 0.3% (versus 1.5% when using bank cards).
Case 2: Crypto Casino for Asian Market
They chose a combination of CoinsPaid (primary) + NOWPayments (backup). Support for 50+ cryptocurrencies attracted players who value anonymity. Fees decreased from 3.5% to 1.2%, withdrawal speed — from 24 hours to 30 minutes.
Case 3: Global Brand with Licensing in Multiple Jurisdictions
They use PaymentIQ as an aggregator managing 12 different providers. A single API simplified development, cascading increased approval rate from 78% to 89%, generating an additional $2.3M monthly.
Technical Integration: What You Need to Know
API and Documentation
A quality payment gateway provides:
- Detailed REST API documentation with request and response examples for all endpoints
- SDKs for popular languages (PHP, Python, Node.js, Java, C#) with ready-to-use examples
- Sandbox environment for testing with test cards and ability to simulate various scenarios
- Webhooks for processing callbacks on transaction status in real-time
- Ready-made plugins for popular casino platforms (SoftSwiss, EveryMatrix)
- Postman collections for quick API endpoint testing
- Detailed error codes with clear descriptions and resolution recommendations
A good indicator of provider quality is how easily your developer can understand the documentation. If basic integration can be done in a day — that’s a good sign. If it takes a week just to understand the documentation — look for an alternative.
Integration Time and Resources
Realistic integration timelines depend on requirements complexity:
Basic API integration (deposits with bank cards only):
- Junior developer: 2-3 weeks
- Middle developer: 1-2 weeks
- Senior developer: 3-5 days
Full integration (multiple payment methods + withdrawals + fraud detection):
- 3-4 weeks for an experienced team
- 6-8 weeks for a team without iGaming experience
Integration of multiple providers with cascading:
- 1-2 months + additional routing logic development
- Requires a senior-level architect for system design
Approval Rate and Conversion Optimization
One of the most important indicators of payment gateway effectiveness is approval rate (percentage of successfully processed transactions). On average across the industry, this figure is 75-85%, but can vary significantly depending on the provider, region, and payment method type.
Factors affecting approval rate:
- Fraud detection system quality: Overly aggressive filters block legitimate players, too soft ones let fraudsters through. Balance is critical.
- Relationships with acquiring banks: Providers with direct contracts with banks show higher approval rates than those working through intermediaries.
- Smart routing: Modern systems analyze transaction history and automatically select the optimal route for each payment.
- Retry logic: If a transaction is declined for technical reasons, the system should automatically retry through another channel.
Increasing approval rate from 75% to 85% means an additional 10% of deposits without increasing marketing costs — that’s millions of dollars for an average casino. Read about the importance of conversion and player retention in the article Marketing in iGaming: How to Attract and Retain Players.
Payment Cascading
Professional operators use multiple payment gateways simultaneously (cascading). If the primary provider declines a transaction, the request is automatically redirected to a backup. This increases approval rate by 15-25%.
Cascading scheme:
- Primary gateway: Provider with the best conditions and low fees processes the main transaction flow.
- Secondary gateway: If the first declines the payment, the transaction automatically goes to the second provider.
- Tertiary gateway: For particularly complex cases or specific payment methods.
Such architecture requires competent technical implementation and a unified transaction management system, but pays off through significant increase in deposit conversion.
Practical Implementation Tips
Stage 1: Analysis and Planning (2-3 weeks)
Define your priorities: target markets, expected transaction volumes, preferred payment methods. Conduct an RFP process: send requests to at least 5 providers.
Stage 2: Testing (3-4 weeks)
Get access to sandbox environments of selected providers. Test processing speed, API documentation quality, fraud detection system performance.
Stage 3: Full-scale Implementation (4-6 weeks)
Integrate the payment gateway into the production environment. Set up monitoring of key metrics: approval rate, processing time, number of chargebacks.
Stage 4: Optimization (ongoing)
Regularly analyze data and optimize settings. Conduct quarterly reviews of fee structures.
Trends and the Future of Payment Systems in iGaming
Open Banking and Instant Bank Transfers
The PSD2 directive in Europe paved the way for Open Banking — a technology that allows direct initiation of payments from a player’s bank account without using cards. Advantages: instant crediting, no chargebacks, lower fees than cards (0.5-1.5%).
Providers like Trustly, Zimpler, and Klarna are already actively implementing this technology in Scandinavian countries.
Biometric Authentication
Face ID, Touch ID, and other biometric methods are gradually replacing traditional passwords and 3D Secure. Apple Pay and Google Pay already use biometrics, and payment gateways for iGaming are moving in the same direction.
Blockchain and DeFi
Decentralized finance opens new possibilities: smart contracts for automatic payouts, asset tokenization, transparency through public blockchain. Read more about blockchain development in gambling in the article Blockchain and Cryptocurrencies in iGaming.
AI-powered Fraud Detection
Artificial intelligence analyzes hundreds of parameters in real-time: behavioral patterns, geolocation, device type, data entry speed. Machine learning identifies anomalies while minimizing false positives. Read more about the role of AI in the article The 5 Biggest Trends in Online Gambling in 2025.
Instant Withdrawals
Instant withdrawals are one of the main trends. Players want to receive winnings immediately. Technologies like Trustly Pay N Play allow combining registration, deposit, and verification in one click.
Choosing the right payment system is an investment in your online casino’s success. A payment system is not just technology; it’s the interface between your business and players’ money. Make it as smooth as possible.
