Payment Gateway Integration
Receive payments securely: card, PIX, bank slip and other gateways
I integrate your system with Brazil's main payment gateways. You get code that works in production, with error handling, configured webhook and tests that cover critical flows.
What I deliver
- Integration with Cielo (credit and debit card)
- PIX via Bacen API or gateway (Mercado Pago, Stripe, PagSeguro)
- Registered bank slip
- Webhooks for automatic status updates
- Error handling and retries
- Payment reconciliation
- Sandbox environment for testing before production
- Audit logs for tracking
