API Integration for Fintech

Financial technology companies operate in a high-stakes environment where security, regulatory compliance, and millisecond-level performance are non-negotiable. Glyphash builds robust fintech solutions that handle sensitive financial data at scale.

How We Help Fintech

Fintech integration connects your platform with banking networks (SWIFT, ACH, SEPA), payment processors (Stripe, Adyen), market data providers (Bloomberg, Reuters), and KYC/AML verification services. We build secure, PCI-compliant API layers with real-time transaction processing.

  • → PCI-DSS, SOX, and financial regulatory compliance
  • → Real-time transaction processing at massive scale
  • → Fraud detection and prevention requirements
  • → Legacy banking system integration challenges

Frequently Asked Questions

What is the difference between REST and GraphQL APIs?

REST APIs use fixed endpoints that return predefined data structures, making them simple and widely supported. GraphQL APIs let clients request exactly the data they need in a single query, reducing over-fetching and under-fetching. We recommend GraphQL for complex, data-heavy applications and REST for simpler integrations.

How do you ensure API security?

We implement industry-standard security practices: OAuth 2.0 for authentication, HTTPS/TLS for encryption, rate limiting to prevent abuse, input validation to prevent injection attacks, and API key management with rotation policies. All APIs include comprehensive logging and monitoring.

Can you build integrations with third-party services?

Yes. We have experience integrating with hundreds of third-party APIs including payment processors (Stripe, PayPal), CRMs (Salesforce, HubSpot), communication platforms (Twilio, SendGrid), cloud storage (S3, GCS), and many more. We also build custom middleware for legacy systems that lack modern API interfaces.
