Integration Scenarios

We tailor integrations for: mobile checkout, POS reconciliation, voucher & coupon redemption, loyalty point sync, digital card issuance and merchant receipt notifications.

Core Benefits

• Production-ready code & API docs to shorten time-to-market
• Privacy-first integration — LGPD (Brazil) & global best practices
• Optional deployment support: CI, container images, monitoring
• Localisation & multi-currency support for retail markets

Compliance & Security

We follow PCI‑DSS guidelines for card data, advise on LGPD-compliant data handling in Brazil, and provide secure tokenization flows so sensitive data never touches your systems.

How to Start — API Integration Instructions

1. Share the target app package name (you already provided: br.com.calcard.android.app) and a short list of high-priority features (e.g. catalog sync, click‑collect, loyalty cards).
2. We perform an initial protocol & API surface analysis (2–5 business days) and propose endpoints to implement.
3. Choose reference stack (Node/Python/Go) — we deliver OpenAPI + sample server + SDK.
4. We run integration tests against your staging endpoints, provide Postman collection and monitoring checks.
5. Optional: on-site or remote assistance for production rollout and compliance review.
