Our Service Overview
We are a tech team specializing in App interface integration and authorized API connections, proficient in protocol analysis for Android and iOS, interface refactoring, Open Data integration, and third-party integration. Whether it is real-time exchange rates, personal finance, voucher systems, credit union mobile banking, fund orders, or mining pool/wallet billing and security management, we provide compliant, deliverable API source code and comprehensive documentation.
Compliance Commitment: All work is performed only under client authorization, or via publicly available / authorized APIs. We comply with local privacy and data protection laws and can sign NDAs as needed.
Core Capabilities
- API Implementation: REST/GraphQL, real-time WebSocket push, OpenAPI/Swagger definitions
- Authentication & Security: OAuth2, OpenID Connect, JWT, TLS, device fingerprinting, MFA/2FA integration
- Data Handling: exchange rate caching, bulk exports, financial reconciliation and exception handling strategies
- Delivery Artifacts: runnable sample code (Node.js / Python / Java), OpenAPI/Swagger, Postman collections, automated test scripts
- Rapid Delivery: standardized templates and test cases, typically 5-10 business days for first release
Target App Feature Implementations
The following are tailored implementation examples and key requirements based on the target apps you provided. Each item includes API definitions, authentication flows, error codes, and sample calls.
- Menekşe Döviz: Real-time and historical exchange rate queries, currency exchange API (including fee calculation), limit/market conversion suggestions, exchange rate change alerts subscription (WebHook/Push). Support for third-party rate sources aggregation and caching to ensure consistency and performance under high concurrency.
- Budget Genie Expense Tracker: Ledger entry, category recognition, OCR invoice recognition API, budget reminders and periodic report export. Implement client-device local/server synchronization, CSV/Excel export, and batch import interfaces with third-party accounting systems.
- 1Voucher: Voucher issuance, redemption and validation API, support for QR/barcode ticket validation, single-use/multi-use policies, voucher value conditions (minimum spend, validity), and merchant settlement & reconciliation interfaces. Built-in anti-replay and fraud prevention rules, with sample Web admin backend API.
- InTouch CU Mobile: Credit union mobile interface implementations, including user authentication (MFA), account balances and details, internal transfers, term deposits and loan inquiries. Supports session management, transaction limits, and exporting statements plus card/account linking APIs.
- Fondemain: Fund/wealth product platform interfaces, including product listing, NAV retrieval and caching, buy/sell orders, subscription/purchase/redemption workflows, holdings statistics and P/L calculations. Includes risk checks and transaction history export functionality.
- PESS Mining Wallet App: Mining pool/wallet integration, wallet address management, earnings distribution queries, withdrawal requests, on-chain/off-chain transaction synchronization and confirmations. Provides secure storage guidance for mnemonic/private keys, and a layered cold/hot wallet architecture with alerting.
Deliverables
- Runnable sample code (Node.js / Python / Java) with deployment and configuration guidance
- OpenAPI/Swagger documentation, Postman collections, including headers and authentication examples
- API integration test plans, automated test scripts, and sample data (provided for authorized integrations)
- Security and compliance recommendations documentation (e.g., PSD2, PCI-DSS, regional data protection considerations)
Pricing & Service Process
- Transparent pricing: starting at $300 (final quote based on complexity); supports delivering samples first with payment upon acceptance
- Process: Requirements confirmation → Authorization & data source validation → Protocol analysis → API implementation → Testing → Documentation delivery
- Compliance safeguards: work only on client authorization or public data sources; NDA and compliance consulting available
FAQ
Q: Is App name alone enough to start a project?
A: Typically yes. We will coordinate to determine what authorization credentials, test accounts, or API documents are required, and guide you to obtain open interfaces or sign authorization if needed. If protocol-level reverse engineering is required, we will pursue it after obtaining authorization and provide a compliance assessment.
Q: Do you support multi-country currencies and localization?
A: Yes. For currency apps like Menekşe Döviz or Fondemain, we implement multi-currency and time zone-friendly APIs, with localization data field recommendations.
Q: How is security ensured?
A: We integrate standard security controls (TLS, key management, least privilege, encryption of sensitive data) and provide security guidance and implementation documentation.
