White-label API integration enables fintech companies to deliver payout experiences under their own brand while leveraging Phaze’s global infrastructure. This approach maintains brand consistency, improves user trust, and reduces friction in the payout flow. Unlike redirect-based solutions, white-label integration keeps users within your application throughout the entire transaction process.
The integration architecture is designed for flexibility. Phaze provides a REST API that you can integrate directly into your existing application flow. This means you control the entire user interface, from brand selection to transaction confirmation. The API handles the complexity of connecting to 2,500+ brands and 500+ mobile carriers behind the scenes, while your application presents a seamless, branded experience.
Implementation begins with sandbox access. After receiving API credentials from support@phaze.io, developers can start testing immediately using our Postman collection. The sandbox environment provides realistic test data and simulates all transaction states, allowing you to build and test the complete user flow before production deployment.
Brand selection is a critical component of white-label integration. The Phaze API provides endpoints to query available brands by country, category, and denomination. You can filter and present these options to users based on your business logic. For example, a rewards app might prioritize dining and entertainment brands, while a payment platform might focus on cash-equivalent options. The API returns brand metadata including logos, descriptions, and pricing, which you can display in your custom interface.
Authentication and security are handled through API keys and SHA256 signatures. Each request requires generating a signature based on the HTTP method, request path, secret key, and request body. This ensures request authenticity and prevents tampering. The signature generation process is documented with examples in multiple programming languages, making implementation straightforward for development teams.
Webhook configuration is essential for real-time transaction updates. Phaze sends webhook notifications for all transaction state changes, including success, failure, and refund events. Your application should implement a webhook endpoint that verifies the signature, processes the event, and updates your internal systems accordingly. This enables features like instant transaction confirmation, automated refund processing, and real-time balance updates.
Error handling requires careful consideration. The Phaze API returns detailed error codes and messages that help diagnose issues. Common scenarios include insufficient balance, brand unavailability, and rate limiting. Your application should handle these gracefully, providing clear feedback to users and implementing appropriate retry logic for transient failures. The API documentation includes a comprehensive error code reference to guide implementation.
Performance optimization involves several strategies. Implement request caching for brand catalogs, which change infrequently. Use asynchronous processing for non-critical operations like transaction logging. Consider implementing request queuing for high-volume scenarios to prevent API rate limit issues. The Phaze API supports batch operations where applicable, reducing the number of individual API calls.
Testing and quality assurance should cover multiple scenarios: successful transactions, various failure modes, network interruptions, and edge cases like duplicate requests. The sandbox environment supports all these scenarios, allowing comprehensive testing before production. Additionally, implement monitoring and alerting for production webhook endpoints to ensure reliable event processing.
Production deployment follows a standard workflow: complete sandbox testing, configure production API keys, verify webhook endpoints are accessible, and implement monitoring. Phaze provides dedicated support during the transition to production, including assistance with webhook verification and troubleshooting any integration issues.
The business benefits of white-label integration are significant. By keeping users on your platform, you maintain control over the user experience, reduce abandonment rates, and strengthen brand loyalty. The unified API eliminates the need to manage multiple provider relationships, reducing operational overhead. Additionally, Phaze’s partner program enables revenue generation through transaction margins.
Best practices for white-label integration include maintaining consistent branding throughout the payout flow, providing clear transaction status updates, implementing robust error handling, and optimizing for mobile devices where many payout transactions occur. Regular API updates and new feature releases are communicated through our developer channels, ensuring your integration remains current with platform improvements.
