India’s digital lending ecosystem has transformed dramatically in the last few years. Borrowers expect instant approvals, paperless onboarding, and smooth user journeys—much like the experience offered by popular lending apps such as PaySense, KreditBee, MoneyTap, and others. Behind the scenes, these seamless journeys are powered by intelligent KYC workflows designed for speed, compliance, and accuracy.
If you're building a modern loan app and want to replicate the efficiency of PaySense, you need solid Aadhaar eKYC integration, PAN verification, and DigiLocker KYC integration stitched together in a compliant, frictionless onboarding flow.
This guide breaks down exactly how to build a PaySense-style KYC integration using Aadhaar, PAN, and DigiLocker—step-by-step, technically and strategically.
Why PaySense-Style KYC Flows Work So Well
A PaySense-like loan journey works because it balances:
Regulatory compliance (RBI mandatory KYC rules)
User convenience (minimal steps)
Fraud prevention (identity + document checks)
Data accuracy (OCR, DigiLocker, verified sources)
A robust PaySense KYC flow typically consists of:
Phone verification + basic details
PAN verification (identity + financial compliance)
Aadhaar OTP-based eKYC (address + identity)
DigiLocker document fetch (proofs, income docs, etc.)
Risk scoring + decisioning
Together, this forms a complete Digital lending KYC automation workflow any lending app must implement to stay competitive.
Core Components of a PaySense-Style KYC Stack
1. PAN Verification API
PAN is the foundation of KYC for lending apps. It helps you:
Validate user identity
Prevent duplicate profiles
Fetch financial and compliance history
Enable credit scoring
A standard PAN verification API returns:
Name match
PAN validity
PAN status (active/inactive)
Masked PAN details
Source verification (NSDL/Income Tax Dept)
Most PaySense-style flows perform PAN verification early to weed out fraudulent attempts.
2. Aadhaar eKYC Integration
This is the fastest way to conduct RBI-compliant identity verification. Aadhaar OTP-based KYC provides:
Name
DOB
Gender
Address (as per Aadhaar)
Masked Aadhaar number
This powers KYC onboarding for loan apps with real-time verification.
Why Aadhaar eKYC is essential:
Works instantly
Accurate and reliable
Allowed under Aadhaar Act for regulated entities
Great for reducing onboarding friction
3. DigiLocker KYC Integration
DigiLocker is one of the most powerful tools for RBI-compliant KYC workflow because it allows users to share:
Aadhaar XML
PAN
Driving License
Voter ID
Address proofs
Income documents
Bank statements (depending on issuer availability)
A good PaySense-like loan app KYC flow uses DigiLocker to auto-validate documents without manual uploads.
PaySense-Style KYC Flow: Step-by-Step Breakdown
Below is how you can structure your own onboarding flow:
Step 1: Collect Basic Details
Mobile number
Full name
Email (optional)
Consent for KYC
Step 2: Mobile OTP Verification
This reduces spam and fake registrations.
Step 3: PAN Verification
Validate PAN using an API:
Auto-fill full name
Check validity
Compare user-entered name vs PAN name for mismatch detection
Step 4: Aadhaar eKYC (OTP Flow)
This step returns verified identity + address automatically.
Step 5: DigiLocker Document Fetch
Used for:
Address proof
PAN card
Driving license
Bank statements
Income documents
Step 6: Video KYC
Useful for NBFCs or apps requiring higher compliance.
Step 7: Risk Scoring + Final Decision
Combine:
PAN results
Aadhaar results
DigiLocker documents
Device intelligence
Credit bureau data
This forms your full PaySense-style KYC integration workflow.
Sample KYC Orchestration
import axios from "axios";
const API_KEY = process.env.FINTEGRATION_API_KEY;
// PAN Verification
export async function verifyPAN(panNumber) {
const response = await axios.post(
"https://your-provider.com/pan/verify",
{ pan: panNumber },
{ headers: { "x-api-key": API_KEY } }
);
return response.data;
}
// Aadhaar eKYC OTP Request
export async function requestAadhaarOTP(aadhaarNumber) {
const response = await axios.post(
"https://your-provider.com/aadhaar/otp",
{ aadhaar: aadhaarNumber },
{ headers: { "x-api-key": API_KEY } }
);
return response.data;
}
// DigiLocker Document Fetch
export async function fetchDigiLockerDocs(authCode) {
const response = await axios.post(
"https://your-provider.com/digilocker/fetch",
{ code: authCode },
{ headers: { "x-api-key": API_KEY } }
);
return response.data;
}
// Unified KYC Flow Controller
export async function runKYCFlow(pan, aadhaar, digilockerCode) {
const panData = await verifyPAN(pan);
const aadhaarData = await requestAadhaarOTP(aadhaar);
const digilockerData = await fetchDigiLockerDocs(digilockerCode);
return {
panData,
aadhaarData,
digilockerData,
status: "KYC_COMPLETE"
};
}
This code demonstrates:
PAN verification
Aadhaar OTP initiation
DigiLocker fetch
Unified orchestration layer
Perfect for FinTech dev teams wanting a modular KYC engine.

FAQ
What exactly is a PaySense-style KYC flow?
A PaySense-style KYC flow is a fast, mobile-first onboarding journey used by modern loan apps like PaySense, KreditBee, and MoneyTap. It combines PAN verification, Aadhaar OTP eKYC, and DigiLocker document retrieval to verify users quickly, securely, and with minimal friction. The goal is to reduce drop-offs and complete KYC within 1–2 minutes.
Why do lending apps use Aadhaar, PAN, and DigiLocker together?
Aadhaar, PAN, and DigiLocker each serve a different purpose:
PAN confirms identity and financial compliance.
Aadhaar eKYC verifies personal details and address instantly.
DigiLocker provides official documents like address proof, PAN card, DL, or income proofs.
When combined, they create a complete, RBI-compliant KYC workflow that stops fraud and speeds up approvals.
Can small FinTech startups implement these KYC flows easily?
Absolutely. Most API providers now offer ready-made PAN, Aadhaar, and DigiLocker integration tools with sample code, SDKs, and sandbox environments. With the right architecture, even early-stage teams can build a PaySense-like loan app KYC journey in a few days. FintegrationFS often helps founders implement the entire stack with clean, production-ready code.
Is Aadhaar eKYC legal for digital lending apps in India?
Yes—Aadhaar OTP-based eKYC is permitted for regulated entities such as NBFCs and banks, as long as the workflow is consent-driven and respects UIDAI guidelines. Most digital lenders use this method because it is fast, accurate, and highly reliable for identity verification.
What’s the biggest mistake teams make when building KYC onboarding?
The most common mistake is treating KYC as a set of standalone APIs instead of a unified flow. Users don’t want to complete five separate steps—they want a single, smooth journey. Successful apps orchestrate PAN, Aadhaar, and DigiLocker into one continuous KYC experience, reducing friction and maximizing conversions.
