Overseas App Interface Integration & API Integration Services

About Us

We are a tech team specializing in App interface integration and authorized API integration, with years of hands-on experience in mobile applications and fintech projects. We offer a one-stop service from protocol analysis, API refactoring, and Open Data integration to third-party service connectivity, automation scripting, and complete documentation delivery.

Compliance note: All projects are based on client authorization or public/licensed APIs (Open Data / Authorized Interfaces). NDAs are signed before work, and we comply with local laws and privacy protections.

Our Core Capabilities

• Cross-platform support: Android / iOS protocol analysis and API implementation
• Authentication & security: OAuth2, OpenID Connect, TLS, signature verification and rate-limiting strategies
• Real-time data integration: WebSocket / Server-Sent Events for quotes, alerts and notifications
• Payments & settlement: integration with third-party payment gateways, wallets, transfers and reconciliation workflows
• Documentation & deliverables: OpenAPI/Swagger, Postman collections, sample code (Node.js / Python / Java)
• DevOps support: CI/CD scripts, automated testing and deployment guides

Target App Scenarios and Key Implementation Points

Below are recommended functionality and interface design points for the target apps you provided (implemented per client authorization and open interfaces):

• Sproutly Mobile: Interface implementation for agriculture/supply chain or e-commerce mobile scenarios, including product/batch traceability API, inventory and order synchronization, QR code traceability, user wallet and settlement, webhook callbacks and multi-language localization support. Key notes: on-chain / tamper-evident logs (optional), incremental synchronization with breakpoint resume under bandwidth constraints.
• HW Markets Assistant App: Market data and trading assistant solution, providing real-time quotes subscription (WebSocket), historical K-line queries, order placement and cancellation, strategy backtesting data export and risk alerts. Key notes: high data throughput and low latency, tiered permission control and rate limiting, unified quotes normalization layer.
• i.Insure: Insurance mobile API suite including policy inquiries, underwriting calculator, online claims submission (photos/files), claim progress callbacks, underwriting status synchronization, and premium autopay integration. Key notes: compliant document storage (encryption/access control), asynchronous tasks and idempotent design.
• Provident Bank: Bank-grade interfaces: customer login with multi-factor authentication, account balance and transaction history, internal and interbank transfers, electronic statements, card management, ATM/branch search and event alerts. Key notes: meet banking compliance and auditing logs, strong session management and anti-fraud strategies.
• Banesco RD: Latin America multi-currency banking integration points: multi-currency accounts, cross-border remittance interfaces, bulk payments and payroll, local payment channels integration (local real-time payments), regional compliance and tax data export. Key notes: localization, time zones and holiday rule handling.
• Muhasib By SRQ Companies: Accounting/app bookkeeping interface providing general ledger entries, invoice/receipt archiving, tax report exports (CSV/JSON/XML), automated reconciliation and variance analysis, audit logs and permission granularity. Key notes: voucher idempotence, chart of accounts mapping and multi-organization/multi-ledger support.

Deliverables (Standard Package)

• Runnable API sample code (Node.js / Python / Java) and deployment notes
• OpenAPI/Swagger documentation and Postman collections with header and authentication examples
• Authentication and security implementation details (OAuth2, signatures, rate limiting, logging)
• Automated testing scripts and integration test plans
• Deployment guidance, operations scripts, and security/compliance recommendations

Implementation Process & Timeline

1. Requirements confirmation and authorization document collection (1-2 business days)
2. Protocol and API analysis, design of the integration plan (2-5 business days)
3. Interface implementation, testing and documentation drafting (typical 3-12 business days depending on complexity)
4. Delivery, deployment support and handover of running scripts and docs (1-3 business days)

The actual timeline may adjust based on interface complexity, third-party approvals (bank/insurance compliance) and client cooperation.

Pricing & Service Guarantee

• Transparent starting price: $300 for basic analysis or small-scale interface delivery; complex projects priced by scope
• Deliver a prototype or sample first; payment after client acceptance (negotiable); NDA available
• Work only under client authorization or open/public interfaces; strict privacy and compliance adherence

Frequently Asked Questions (FAQ)

1) What information do you need from us?

Please provide the target App name (e.g., Sproutly Mobile / HW Markets Assistant App / i.Insure / Provident Bank / Banesco RD / Muhasib By SRQ Companies), the interface requirements, any existing API authorization credentials or documentation, and preferred delivery formats.

2) Do you support real-time quotes or push notifications?

Yes. We implement WebSocket / SSE for real-time data and asynchronous notifications (webhooks), with subscribe/unsubscribe and replay strategies.

3) How do you ensure data security and compliance?

We use encrypted transmission (TLS), authentication (OAuth2/OpenID), access control, audit logs, and data minimization. Localized compliance guidance is provided when needed.
