What Is an Identity Verification API?

An identity verification API is a software interface that allows FinTech platforms to automatically verify a user’s identity using official documents and data sources. These APIs integrate seamlessly into mobile apps, websites, and backend systems to validate customer identities in real time.

Typically, identity verification APIs support:

• Government ID verification (Aadhaar, PAN, Passport, Voter ID, Driving License)
• OCR-based document data extraction
• Biometric and face verification
• Database and government registry checks
• AML and fraud risk assessment

For FinTech platforms, these APIs form the backbone of digital onboarding and compliance workflows.
