Implementation Workflow

SePay Implementation

  1. Load references/sepay/overview.md for auth setup
  2. Load references/sepay/api.md or references/sepay/sdk.md for integration
  3. Load references/sepay/webhooks.md for payment notifications
  4. Use scripts/sepay-webhook-verify.js for webhook verification
  5. Load references/sepay/best-practices.md for production readiness

Polar Implementation

  1. Load references/polar/overview.md for auth and concepts
  2. Load references/polar/products.md for product setup
  3. Load references/polar/checkouts.md for payment flows
  4. Load references/polar/webhooks.md for event handling
  5. Use scripts/polar-webhook-verify.js for webhook verification
  6. Load references/polar/benefits.md if automating delivery
  7. Load references/polar/best-practices.md for production readiness

Key Capabilities

SePay:

  • Payment gateway (QR, bank transfer, cards)
  • Bank account monitoring with webhooks
  • Order-based virtual accounts
  • VietQR generation API
  • 44+ Vietnamese banks supported
  • Rate limit: 2 calls/second

Polar:

  • Merchant of Record (global tax compliance)
  • Subscription lifecycle management
  • Usage-based billing (events, meters)
  • Automated benefits (GitHub, Discord, licenses)
  • Customer portal (self-service)
  • Multi-language SDKs
  • Rate limit: 300 req/min

Instructions

When implementing payment integration:

  1. Identify platform based on requirements (Vietnamese vs global, payment types)
  2. Load relevant references progressively as needed
  3. Implement authentication using platform-specific methods
  4. Set up products/pricing according to business model
  5. Implement checkout flow (hosted, embedded, or API-driven)
  6. Configure webhooks with proper verification
  7. Handle payment events (success, failure, refund)
  8. Test thoroughly in sandbox before production
  9. Monitor and optimize using platform analytics

Load only the references needed for current implementation step to maintain context efficiency.
