The API Challenge in Financial Services
For NBFCs
-
Legacy systems are limiting the ability to launch agile lending products
-
Fintech integrations require secure, scalable APIs
-
RBI compliance and risk reporting need structured, auditable API flows
For Banks
-
Monolithic cores hinder real-time operations and innovation
-
Open banking mandates drive third-party API enablement
-
Transaction-heavy systems demand high performance and airtight security
For Insurers
-
Policy, claims, and customer systems remain siloed
-
Integration with hospitals, brokers, and regulatory bodies is manual and error-prone
-
Digital CX and self-service tools require modern APIs and clean data flows
