CONNECTED FINANCIAL SYSTEMS

Open Banking, Payment & Financial API Integrations for Fintech Apps

Essential standards and APIs such as Open Banking, ISO 20022, ACH, and SWIFT are commonly integrated in modern fintech apps. These integrations are important because they allow fintech apps to communicate with banks, payment networks, financial institutions, and third-party platforms. They help applications exchange financial information and process transactions across different systems.

Personalized Insights	Provides relevant financial recommendations based on permitted customer data.
AI Agents	Automates multi-step tasks across customer service and financial operations.
AI + Financial APIs	Connects AI capabilities with banking, payment, and financial systems.

From smarter fraud monitoring to automated workflows, AI becomes part of the fintech product rather than a separate technology layer.

Modernizing Legacy Fintech Systems for AI Adoption

Old fintech systems may contain valuable information stored for many years and important logic. So you don't have to replace everything at once. We figure out what can be saved, modernized, and where AI can be introduced in a safe manner.

Assess

Legacy Application → AI Readiness → Data & API Assessment

We assess your legacy applications, infrastructure, data, integrations, and processes to find out which ones are ready for AI and what can be improved before implementing AI.

Modernize

Legacy APIs → Cloud Infrastructure → AI-Ready Architecture

We modernize old parts, APIs, data platforms, and infrastructure to build an AI-ready architecture.

Migrate

Financial Data → AI/ML Models → LLMs → Cloud AI

We migrate financial data, existing AI/ML models, LLM workloads, and other services while keeping the operation of financial processes uninterrupted.

Optimize

Security → Compliance → Performance → Scalability

We optimize the migrated environment through additional security, compliance controls, and performance to handle growing transaction volumes and AI workloads.

Instead of migrating an old fintech system to modern technology, we prepare it for further development of its financial product.

Fintech App Security: Protecting Data, Transactions & Users

The problem with a fintech app is that it isn’t just one login screen to protect. It is a set of experiences, from opening an account to navigating the application and making transactions. Each of them requires its own level of security. And here’s how we do it at every step.

Step 1: Create the Account

Identity and Access Security

Each new user session begins with authentication. We create access controls that will ensure user authentication without compromising performance.

Multi-Factor Authentication (MFA)Include additional verification before a user accesses the account or performs critical actions.
Biometric AuthenticationEnable fingerprint and facial authentication for devices where it is possible.
Role-Based Access Control (RBAC)Ensure that users, employees, and admins have access based on their roles.
Session ManagementManage user sessions and make them time-limited to reduce vulnerability.
Prevent Account Takeover and Credential Stuffing AttacksPrevent automated logins with stolen credentials.
API SecuritySecure all requests to your app, internal systems, and financial institutions.

Stage 2: Actions within the App

API Security

Once inside, users make dozens of API calls each session. Each call may be an entry point; therefore, you must verify and monitor every call.

OAuth 2.0 & OpenID ConnectGrant permission for authentication of requests between your app, services, and third-party financial applications.
JWT SecurityEnsure that the tokens are signed and validated to avoid request forgery or repetition.
Certificate PinningPrevent attackers from being able to use fraudulent certificates to steal the traffic.
Rate LimitingAvoid any possible abuse by limiting API calls.
API Gateway SecurityManage all the integrations, not just login.

Stage 3: Storing Information

Data Security

Information is either at rest or in transit at all times. These require individual security measures.

Encryption at Rest (AES-256)Securing data stored in databases and storage facilities.
Encryption in Transit (TLS)Securing data transmission between apps, APIs, servers, and financial partners.
End-to-end EncryptionEnsuring data remains protected on its journey from one endpoint to another.
Encryption Key ManagementProperly storing and rotating encryption keys for them to be effective.
Tokenization & Data MaskingUsing tokens to replace sensitive payment information wherever possible.

Stage 4: Transfers Money

Transaction Security

The stage with the highest stakes is where we monitor all transactions for unusual activity.

Real-Time Fraud DetectionAnalyzing the behavior of transactions and identifying any fraudulent activity.
Transaction Monitoring & Risk AnalysisMonitoring all financial activity and alerting on any unusual transactions.
Payment TokenizationProtecting card and account numbers in all transactions.
Non-repudiationMaking sure there is no denying the transaction.
Audit LogsMaintaining logs of all account, transaction, security, and administrative activity.

Stage 5: Under the Hood

Security Testing

But all of this does not mean anything without constant testing. We incorporate security testing into development, not just the release process.

Vulnerability Assessment & Penetration TestingEvaluate apps, APIs, third-party libraries, and the infrastructure for any vulnerabilities.
SAST & DASTScan source code and running applications for bugs throughout the process.
OWASP MASVS ComplianceTest your mobile applications against storage, cryptography, and authentication standards.
Detection of Root and JailbreakingIdentify tampered devices prior to accessing sensitive functionality.
Anti-Tampering & RASPDetect and stop any attempts to modify your app at runtime.
Secure CodingFinding common bugs such as SQL Injection, XSS, and Broken Access Control at early stages.

Security is not a feature. It’s a combination of various measures protecting your users, financial information, transactions, and all systems involved in your application.

Trust & Regulation

Fintech Compliance: Navigating KYC, AML, Payments & Regulations

Every fintech product needs to answer the same three questions, regardless of its target audience or market. Your product’s requirements are mapped against those questions. As a result, they are translated into your business workflows and technologies tailored to the market you’re working in.

Who Are My Users, and What Do I Owe Them?

You should always know to whom your service is provided. This is the responsibility of KYC. But AML stays on top of it to keep an eye.

Identity Verification
Customer Due Diligence
Sanctions & Watchlist Screening
Transaction Monitoring
Risk-Based Review Workflows

How Is Money Transferred, and What Regulations Apply?

Different models of payments require different regulations. This framework is built into payment and banking workflows in your app.

PCI DSSApplicable Payment Card Industry Data Security Standard.
PSD2Applicable European Payment Regulations & Strong Customer Authentication Regulations.
Open BankingSecure Access to Financial Data and Payment Services, if applicable.
RBI RequirementsApplicable for Fintech Products Working in India.

What Will Happen With the Data That I Hold?

A lot of personal information is used by financial products. Where relevant, we build compliance around the following.

GDPRPersonal data protection obligations.
SOC 2Security and operational controls for your service environment.
Data GovernanceFinancial information management, access, retention and protection.
AuditabilityDocuments that facilitate security, operational and compliance audits.

Where Are You Running Your Business From?

Depending on the market, the same fintech product will have to comply with different regulatory obligations. The solution we build will cover your particular footprint, rather than some standard region.

United StatesRelevant state-level money transmitter regulations and other US financial regulations.
European UnionGDPR and PSD2 regulations, if your product is targeting EU users or payments.
IndiaRBI regulations and other data protection regulations relevant for fintech products.
UAEDIFC and Central Bank regulations relevant for financial products.
AustraliaFinancial services and privacy obligations for the local market.

Expert Insight

According to our fintech IT expert Pramod Jangid, there is no universal fintech compliance checklist. Requirements shift by product, country, and business model. We design applications with the applicable requirements in mind, and integrate the right controls for your target market from day one, not after the product is already built.

What Actually Moves the Number

Two apps in the same tier will not necessarily fall at the same end of the spectrum. Here’s what raises cost, and what lowers it.

Features
The more screens and workflows that go beyond the basics, the longer the build process.
Platforms
iOS, Android, and web each add development time, unless you’re building cross-platform from the start.
APIs
The complexities of bank, card network, and payment gateway integrations vary greatly.
Compliance
PCI DSS, GDPR, or RBI compliance means added design and testing work upfront.
Security
Encryption, fraud protection, and audit logging are not optional extras but must be built into the app.
Integrations
Integrations with core banking, KYC providers, and third-party financial tools each increase scope.
User interface and experience
Original UI/UX design is more expensive than customization.
Backend complexity
Real-time transactions cost more than mere record-keeping.
Scalability
Scalable architecture right from the start costs more than a bare minimum viable product approach.
Third-party services
Fraud, analytics, and notification services increase both development time and ongoing cost.

Fintech Mobile App Development Timeline: How Long Does It Take?

Generally, it takes 3 to 5+ months to develop a fintech app. The final timeline is determined by the platform’s type, complexity, security requirements, and features. AI-assisted development compresses the timeline without cutting corners on testing or compliance. Most fintech builds, across all three tiers, land between three and five months.

Fintech App Level	Timeline	Core Scope	Key Timeline Drivers
Basic	~3 Months	Core features, dashboard, APIs, basic AI	Features, UI/UX, testing
Mid-Level	3–4 Months	Advanced workflows, integrations, analytics, AI	APIs, security, AI, testing
Advanced	4–5 Months	Real-time transactions, AI/ML, compliance	Integrations, security, scalability

Custom Payment App Development vs White-Label Solutions: Which Delivers Better Long-Term Value?

The budget, business goals, and long-term growth plans help in selecting the right development approach. Both custom and white-label development options are compared below to help you choose one. Businesses should choose the option that offers them the best value, flexibility, and scalability for a payment platform. Here's the side-by-side, factor-by-factor comparison between custom payment app development vs. white-label solutions.

Criterion Custom Development White-Label Platform

Time to Launch 4–7 months, built from scratch 3–6 weeks on an existing core

Upfront Cost Higher — full development scope Lower — license fee + setup

Customization Depth Full control — every checkout flow, rule, and screen is built to spec Limited to what the vendor's platform allows

Code Ownership You own the codebase outright, no dependency on a vendor Licensed access — the vendor keeps the underlying platform

Scalability Ceiling Built around your own transaction volume and growth plans Limited by the vendor's shared infrastructure capacity

Total Cost of Ownership Lower over time — no ongoing license payments License costs accumulate the longer you run on it

Compliance Control You define audit scope, data residency, and which certifications to pursue Tied to whatever compliance posture the vendor already holds

Best Fit A payment product built to last, with a distinct experience Quick market testing, tighter budgets

Choose Custom Development When

Payments are central to your business, not an add-on feature
You need flows that no packaged platform currently offers
You operate in a market with compliance rules that demand full audit visibility
You expect transaction volume to outgrow a shared platform's limits
Owning the IP and controlling long-term cost matters more than launching fast

Choose White-Label When

You want to test market demand before investing in a full build
Your feature set is standard — payments, top-ups, transfers, bill pay
Timeline or budget doesn't allow for a multi-month development cycle
You're willing to rely on the vendor's existing compliance certifications
You see this as a stepping stone toward a custom build later
