Overseas App API Integration & Interfaces Services — Covering Banking, Insurance, Loans and Media Apps

About Us

We provide professional App API integration and authorization API implementation services, adept at protocol analysis for Android and iOS platforms, Open Data integration, and third-party API connections. Our team has extensive hands-on experience in fintech, insurance, and media apps, capable of delivering secure, compliant, and highly available interfaces based on client authorization.

Compliance: All work is conducted based on client authorization or publicly available/licensed APIs, in compliance with local laws and privacy protections. NDA available if needed.

Core Capabilities

• Protocol analysis and API refactoring: supports HTTPS, OAuth2, JWT, mutual TLS authentication and message standardization
• Open Data and third-party service integration: payment gateways, credit bureaus, KYC/AML services, push/message services
• Automation scripts and testing: Postman collections, automated regression scripts, CI integration examples
• Deliver runnable sample code (Node.js / Python / Java), OpenAPI/Swagger docs and integration guides
• Data protection and security: TLS, key management, least privilege policy and audit logging recommendations

Implementation Highlights for Your Apps

The following are typical interface design points and deliverables for each app based on your latest requirements:

• Pass.mn: For mobility and digital credential scenarios, provide account login (phone number + OTP), e-ticket lookup, transaction history synchronization, top-up/refund interfaces, offline credential validation, and push notification integration. Deliverable: mobile SDK packaging and backend microservice samples.
• YRF Production: For film/production company apps, provide content catalog and streaming authentication APIs, subscription and billing callbacks, DRM/license integration recommendations, cover image and metadata synchronization API, and playback quality and analytics reporting interfaces (useful for ads/revenue analysis).
• 교보라플 – Insurance Experience App (Korean Insurance Experience App) Implement underwriting flow APIs (quoting, underwriting, policy generation), claims filing interface, policy management, customer KYC and identity verification (local regulatory compliance), notifications and multilingual support. Documentation will include insurance workflows and end-to-end sample requests/responses.
• PNB ONE: For retail banking apps, provide login / MFA, account and balance inquiries, real-time transfers, bill payments, transactions history and reconciliation export interfaces, and support for local payment networks (e.g., UPI/ACH) integration and limit controls. Deliverables include security hardening recommendations and fraud/risk control integration points.
• Kard: Focused on virtual cards and expense management, provide card generation/binding, virtual card limits and freezing, real-time spend notifications, categorization and budgeting APIs, and authorization & reconciliation with payment gateways / issuing banks. Sample code covers frontend calls and backend signature verification.
• SINGA - Pinjaman Uang Online [com.asf.singa]: Online lending platform interfaces including loan application forms, credit scoring engine integration, repayment plans and installment calculations, overdue management and collections process recommendations, strict KYC/AML interfaces, and compliant disclosures templates for fees and interest rates. We will deliver test cases and compliance checklists.

Deliverables

• Executable API sample code (Node.js / Python / Java) with deployment instructions
• Postman collections with environment variables, sample requests/responses
• OpenAPI / Swagger standardized documentation for SDK generation
• Testing plans, API security recommendations, and compliance checklist (KYC/privacy/data retention)

Best Practices & Compliance Recommendations

• Only work under client authorization or for publicly available APIs; avoid unauthorized data scraping. If protocol refactoring is needed, use auditable methods and keep operation logs.
• Adopt OAuth2 + PKCE, short-lived access tokens with refresh tokens, paired with TLS 1.2/1.3 to ensure transport security.
• Provide compliance document templates for loan and insurance businesses to help clients meet local regulatory disclosure, collection, and interest-rate calculation requirements.

FAQ

What information is needed to start?

Please provide the target App names (e.g., Pass.mn, YRF Production, 교보라플, PNB ONE, Kard, SINGA) and specific requirements (e.g., account inquiries, payment integration, or lending flow), and confirm authorization scope or provide publicly available API documentation.

What is the typical development cycle?

Depends on complexity and authorization. Standard integration (auth, account inquiries, basic transactions) generally takes 5–10 business days; complex scenarios (credit checks, DRM, cross-border settlements) may require 2–4 weeks.

How do you ensure compliance and data security?

We develop only with client authorization or based on public APIs, using industry-standard encryption and least-privilege principles. NDA can be signed when needed, with a compliance checklist provided.

Pricing & Service Process

• Transparent starting price: $300, with sample deliverables up front and payment upon client acceptance
