Subscription, Payment & Shared Microservices
Subscription management, payment, file management, authentication and e-mail services that different products can integrate with easily.
Highlights
- Subscription service with automatic billing, plan changes, card management and customer-specific plans.
- Common integration interface for Paddle, Stripe and PayPal that syncs customers, products and prices with third parties.
- Retry-friendly synchronization design where integration failures never break the primary operation.
- Shared core library for .NET projects (OnurC.Core) covering JWT, caching, e-mail, pagination and Result patterns.
