What Is an Aadhaar Verification API Provider

An Aadhaar Verification API Provider is a technology platform or authorized service partner that supplies software tools to connect business applications directly with government identity databases for real-time authentication.

Aadhaar Verification API Provider Work?

An Aadhaar Verification API Provider acts as an authorized technology middleman that allows businesses to instantly confirm a user’s identity against the Unique Identification Authority of India (UIDAI) database. Since most businesses cannot connect directly to government servers due to strict infrastructure audits and compliance costs, they use a Sub-AUA (Authentication User Agency) model provided by these tech vendors to perform real-time digital onboarding, e-KYC, and fraud checks.

How the Aadhaar Verification API Works

The technical workflow typically follows a simple four-step Aadhaar Verification API request and response mechanism:

Input Submission: The customer inputs their 12-digit Aadhaar number, uploads an image of the card, or initiates an OTP request via the business’s application frontend.
Data Extraction & Routing: If a card image is uploaded, the API uses Machine Learning OCR to read the text fields. The Aeps india then securely packages the request and routes it through authorized Authentication Service Agencies (ASAs) directly to the UIDAI backend.
Database Validation: The UIDAI database instantly validates whether the credentials match its central records.
Structured Response: The Aadhaar Verification API receives the encrypted confirmation and returns a JSON or XML response payload back to the business. This payload delivers verified profile attributes such as full name, date of birth, gender, address, and profile photograph.

Aadhaar Verification API Provider Service Offered

An Aadhaar Verification API is a secure software bridge that enables businesses to instantly cross-reference and authenticate an individual’s identity details against the centralized Unique Identification Authority of India (UIDAI) database.

Integrating this service automates the Know Your Customer (KYC) compliance process, reducing digital onboarding times from days to mere seconds while offering heavy protection against identity fraud.

Core Services Offered by API Providers

Aeps india typically offer a combination of the following validation methods depending on operational and regulatory requirements:

• OTP-Based Authentication (eKYC / OKYC): Generates a one-time password sent to the customer’s UIDAI-registered mobile number. Once validated, it securely extracts demographics and user photos.
• Biometric & Face Authentication: Utilizes physical biometric touchpoints (fingerprint/iris scanners) or AI-powered face-matching and liveness detection algorithms for contactless validation.
• Demographic Verification: Performs text-based “Yes/No” matching on provided parameters like full name, gender, and date of birth.
• Offline eKYC (XML / Secure QR): Decrypts secure, machine-readable official QR codes or UIDAI XML files. This downloads user information without invoking real-time OTP roundtrips.
• Privacy-Sensitive Masked Aadhaar & VID: Uses temporary 16-digit Virtual IDs (VID) or yields masked copies to shield raw identity numbers from business storage networks.

Aadhaar Verification Methods Supported by API

The Aadhaar Verification API serves as the digital foundation for identity validation in India, allowing authorized businesses to cross-reference customer identities against the Unique Identification Authority of India (UIDAI) database.

The primary Aadhaar verification methods supported by modern Aadhaar Verification API are split into online (live central database query) and offline (package-based decryption) methods:

Online Aadhaar Verification APIs

These top Aadhaar Verification APIs interact directly with UIDAI’s Central Identities Data Repository (CIDR) in real time:

• OTP-Based Authentication (eKYC / OKYC): The user enters their Aadhaar number, triggering a One-Time Password to their registered mobile number. On successful verification, the Aadhaar OTP verification API retrieves verified demographic details and a photograph.
• Biometric Authentication: Uses UIDAI-registered hardware scanners to capture fingerprints or iris impressions for high-security, in-person scenarios like bank account openings.
• Aadhaar XML / Offline eKYC: Users generate a secure, shareable ZIP or XML file. The Aadhaar identity verification API decrypts it with user consent without requiring direct UIDAI server reliance.
• Face Authentication: Employs AI-driven liveness detection via webcams or mobile cameras to match a live scan against the official photo record.
• Demographic Verification: Performs basic plaintext parameter matching (Name, DOB, Gender, Address) and returns a simple “Yes/No” status without needing an OTP or exposing core biometrics.
• DigiLocker Integration: Allows users to log into their DigiLocker account and securely share fetched documents.
• Virtual ID (VID) API: Allows users to submit a temporary 16-digit VID instead of their permanent 12-digit Aadhaar number to preserve data privacy during online authentication.

Offline Aadhaar Verification APIs

These methods eliminate direct UIDAI server dependency and validate identities locally via digital signatures:

• Offline XML (Paperless eKYC) API: The user uploads a password-protected, digitally signed XML file downloaded from the UIDAI portal. The Aadhaar eKYC verification API uses a 4-digit user-generated Share Code to decrypt and validate the package.
• Secure QR Code API: Decodes the encrypted QR code printed on physical Aadhaar or PVC cards to extract verified demographic information and photos locally.

Aadhaar Verification API Integration

Integrated Aadhaar Verification API allows your business to automate identity verification (KYC) within seconds by securely connecting to the Unique Identification Authority of India (UIDAI) central database. Because Aeps india cannot access the UIDAI database directly, the integration is typically completed through a licensed Aeps india.

Step-by-Step Integration Workflow

1. Setup Environment and Credentials

• Acquire API Keys: Register with an authorized Aeps india to generate your unique sandbox and production Aadhaar Verification API keys.
• Implement Encryption: Configure your server environment to enforce TLS 1.2 or higher (HTTPS) for all API requests to secure data in transit.

2. Capture User Consent (Mandatory)

• Design UI Component: Create an explicit checkbox or pop-up in your User Interface stating exactly how the Aadhaar data will be used.
• Log Metadata: To comply with the Digital Personal Data Protection Act (DPDPA), your backend must programmatically record the precise timestamp, transaction ID, and session ID showing the user gave legal consent.

3. Choose & Trigger the Verification Method

Depending on Aadhaar Verification platform requirements, integrate one of the main verification endpoints:

• OTP-Based eKYC (Remote Onboarding):
  1. Trigger an Initiate Aadhaar OTP verification API call by sending the user’s 12-digit Aadhaar number.
  2. UIDAI sends a One-Time Password to the user’s registered mobile number.
  3. Prompt the user to enter the OTP in your UI and pass it through a secondary Verify OTP endpoint.
• Biometric Authentication (In-Person / Point of Sale):
  • Capture fingerprints or iris scans through UIDAI-approved biometric hardware scanners and pass the encrypted data package to the Aadhaar authentication API India.
• Offline XML / QR Code Verification (Low Complexity):
  • Use Aadhaar card verification API that scan the secure QR code on the physical card or upload a digitally signed Aadhaar XML file, eliminating the need for an active UIDAI OTP server query.

4. Handle Payload and Response

• Format Response: The Aadhaar KYC API returns a signed JSON or XML payload mapping demographic data.
• Parse Extracted Details: Map out the returned metrics such as validity status, full name, gender, masked Aadhaar, date of birth, address, and photo link to populate your database.

5. Strict Security Compliance Post-Integration

• Zero Biometrics Policy: You are strictly forbidden from saving or caching raw biometric data anywhere on your business servers.
• Data Masking: Only store the masked Aadhaar card numbers (displaying only the last 4 digits) inside your client logs.
• Mandatory Auditing: Before taking your integration live, you must complete an initial security assessment conducted by an independent agency empaneled by CERT-In or UIDAI.

Aadhaar Verification API Implementation Process

Implementing an Aadhaar Verification API involves setting up a secure, digital bridge between your business application and the Unique Identification Authority of India (UIDAI) central database. Since private businesses cannot query the UIDAI database directly, you must integrate either as an authorized Authentication User Agency (AUA) or partner with a licensed Aeps india.

The structural and programmatic process to implement Aadhaar Verification API spans five critical phases:

1. Preparation and Environment Setup

Before writing code, establish your legal architecture and testing environment.

• Provider Selection: Choose a trusted Aeps india to leverage their production endpoints and Aadhaar Verification software development kits (SDKs).
• Sandbox Registration: Sign up with your business credentials on the Aadhaar Verification portal to gain Sandbox Access and retrieve test Aadhaar Verification API key.
• Security & Infrastructure: Configure your production environment to enforce TLS 1.2 or higher (HTTPS) for all API requests to ensure encryption-in-transit.

2. User Interface & Consent Architecture

Compliance dictates that user journey workflows must strictly align with Indian data privacy regulations like the Digital Personal Data Protection Act (DPDPA).

• Mandatory Informed Consent: Your front-end UI must display an explicit, unambiguous consent checkbox before collecting any Aadhaar data.
• Data Input Form: Capture the 12-digit Aadhaar number or the privacy-focused 16-digit Virtual ID (VID).

3. Core Technical Workflow (OTP-Based eKYC)

The standard remote onboarding mechanism follows a sequential, secure backend workflow:

• Step 1: Initiate Request: Submit a POST request (e.g., /api/v1/aadhaar/ekyc) containing the user’s Aadhaar or VID and a unique transaction ID to your Aeps india server.
• Step 2: OTP Trigger: UIDAI processes the initial trigger and fires a One-Time Password (OTP) to the mobile number legally linked to that Aadhaar record.
• Step 3: Submit & Verify: Prompt the user for the OTP on your UI, capture it, and dispatch a second API payload to verify the code.
• Step 4: Receive Response: If successful, the endpoint returns a signed JSON or XML payload containing pre-verified demographic details (Full Name, DOB, Address, Gender) and an encrypted photograph.

4. Data Storage & Privacy Policy Enforcement

Strict adherence to UIDAI compliance rules is non-negotiable for system production approval.

• Zero Storage Rule: You are legally prohibited from storing raw Aadhaar numbers or biometrics on your local databases.
• Aadhaar Masking: If you must display or log document proofs, use a Masked Aadhaar utility API to black out the first 8 digits and display only the final 4 digits.
• Metadata Logging: Programmatically log transactional metadata (session ID, unique tracking number, and strict timestamp) to fulfill audit trail criteria.

5. Alternative Verification Integration Methods

Depending on your business requirements, you may optionally implement secondary verification endpoints:

• Offline XML (Paperless eKYC): Processes digitally signed, password-protected XML files shared directly by the user, requiring zero live connection to UIDAI database.
• Secure QR Code Scanning: Best for branch offices or in-person verification; decrypts the physical or digital card’s embedded QR code locally using a camera tool.
• Biometric Authentication: Integrates hardware Aeps fingerprint or Aeps iris scanner SDKs for high-security environments like banking or insurance.

Aadhaar Verification API Developer Documentation

The Aadhaar Verification API enables businesses to authenticate individuals instantly against the Unique Identification Authority of India (UIDAI) database. It is widely used across fintech, banking, and e-commerce sectors to automate digital KYC compliance, eliminate fraud, and streamline user onboarding.

1. Core Verification Workflows

The best Aadhaar verification API typically operates through three primary interaction patterns:

OTP-Based Verification (Most Popular)

• Step 1: The user inputs their 12-digit Aadhaar number into your application frontend.
• Step 2: Your server invokes the Generate OTP endpoint, triggering UIDAI to text a one-time password to the user’s linked mobile number.
• Step 3: The user submits the OTP to your client application.
• Step 4: Your server passes the OTP to the Submit OTP endpoint. Upon a successful match, it retrieves the user’s verified demographic payload.

2. QR Code & Offline XML Verification

• QR Flow: Your app scans the secure QR code printed directly on the physical Aadhaar card. The Aadhaar verification service API parses and validates the internal digital signature locally.
• XML Flow: The user securely shares a digitally signed XML file downloaded from the UIDAI portal, allowing offline identity parsing without an active internet ping back to central government servers.

3. Biometric & Face Authentication

• Used primarily for high-security in-person banking or assisted touchpoints, verifying identities through fingerprint, iris, or real-time face matching.

Example API Payload Structure

Most commercial aggregators, such as the Sandbox Aadhaar KYC API Docs or Aadhaar KYC API Docs, bundle the verified user data inside a standard JSON response framework:

• Error Handling Simulation: Sandbox ecosystems purposefully validate error loops, passing back contextual objects for mock issues such as Invalid OTP, OTP Expired, or Invalid reference ID to help check your application’s logic.

Aadhaar Verification API Webhooks & Real-Time Status

An Aadhaar Verification API connects Aadhaar Verification software applications securely to the Unique Identification Authority of India (UIDAI) database to automate real-time identity authentication and KYC compliance.

How Webhooks & Real-Time Status Work

• Event-Driven Webhooks: Instead of holding an HTTP connection open during long-running or async validation processes, providers use webhooks to dispatch an asynchronous POST request to your designated endpoint once the UIDAI status updates.
• Status Payloads: Webhook payloads typically return standard event types (e.g., aadhaar.verified, aadhaar.failed, or aadhaar.otp_expired) accompanied by matching metadata like request IDs, timestamps, and masked response codes.
• Downtime & Retries: If UIDAI servers experience intermittent outages, reliable webhook systems queue failed requests and push real-time status retry notifications so internal application states do not hang.

Aadhaar Verification API Security & Data Protection

Implementing Aadhaar Verification API requires strict adherence to security protocols mandated by the Unique Identification Authority of India (UIDAI) and the Digital Personal Data Protection Act (DPDPA) to prevent identity fraud and unauthorized data access.

The security architecture of a compliant Aadhaar Verification API is structured around four primary pillars:

1. Data Encryption & Transmission Security

• Transport Layer Security (TLS): All communication between your application, the Authentication User Agency (AUA) / Authentication Service Agency (ASA) servers, and the central UIDAI database is encrypted using industry-standard TLS protocols to prevent intercept exploitation.
• PID Block Security: For biometric data inputs (fingerprints or iris scans), the Personal Identity Data (PID) block must be compiled in a secure binary format and encrypted immediately at the capture device level.
• Tamper-Proof Integrity: For offline validation, the Aadhaar Offline e-KYC XML file is digitally signed by UIDAI, making it fully tamper-proof when processed by the backend Aadhaar offline KYC API.

2. Mandatory Storage Compliance (Aadhaar Data Vault)

• Zero Log Storing: Per UIDAI regulations, raw Aadhaar numbers, biometric payloads, and core authentication data must never be stored in local system storage, Aadhaar Verification app caches, or server log files.
• Aadhaar Vaulting: Regulated entities who are legally permitted to store data must place Aadhaar information inside an Aadhaar Data Vault (ADV). This is a secure, isolated repository protected by Hardware Security Module (HSM) devices.
• Reference Keys & Tokenization: The vault encrypts the 12-digit number and issues a unique tokenized reference key. Your internal customer database uses this token instead of the actual Aadhaar number, keeping the real identity isolated.

3. Access Control & Privacy Safeguards

• API Authentication: Access to the endpoint is restricted using secure Aadhaar paperless KYC API keys, OAuth tokens, and automatic SSL/TLS certificate validation to confirm only trusted systems are communicating.
• Explicit User Consent: Aadhaar OTP API must be architected to trigger only after securing explicit, documented, and revocable user consent as mandated by data privacy laws.
• Virtual ID (VID) Support: To minimize exposure, the system should allow users to supply a temporary, 16-digit revocable Virtual ID (VID) in lieu of their permanent Aadhaar number.

4. Audit & Traceability

• Regulatory Logs: ASAs and AUAs are required to maintain strict audit records of the exact timestamp of every authentication request and its response status.
• No PII in Logs: While tracking success or failure metadata for regulatory audits, the log files themselves must remain completely stripped of any Personally Identifiable Information (PII).

Aadhaar Verification API Compliance & Legal Considerations

Top Aadhaar Verification API require strict compliance with UIDAI frameworks, the Aadhaar Act, and the Digital Personal Data Protection Act (DPDPA) to legally authenticate identities in real time.

Core Legal & Compliance Requirements

• Explicit User Consent: You must capture clear, unambiguous, and informed user consent via your user interface prior to initiating any Aadhaar authentication request.
• Legal Access Architecture: Private entities cannot query the UIDAI database directly; they must operate via authorized Authentication User Agencies (AUA/KUA) or the Sub-AUA/Sub-KUA model.
• Zero Biometrics & Data Minimization Policy: Storing raw biometric data (fingerprints/iris scans) or unmasked Aadhaar numbers is strictly prohibited. Biometrics must be encrypted instantly at the hardware layer via UIDAI-registered devices.
• Audit Trails & Logging: Systems must programmatically log metadata including transaction IDs, session IDs, and timestamps, while undergoing mandatory initial and periodic security audits by UIDAI or CERT-In empanelled agencies.
• Technical Security: All data transmission must leverage end-to-end encryption using TLS 1.2 or higher alongside IP whitelisting and secure Aadhaar authentication API gateways.

Aadhaar Verification API Transaction & Verification Management

An Trusted Aadhaar Verification API is a secure digital bridge that connects business applications directly to the Unique Identification Authority of India (UIDAI) database to instantly confirm a person’s identity.

Core Verification Methods

• OTP-Based Authentication: Sends a One-Time Password to the user’s Aadhaar-linked mobile number for fast remote eKYC.
• Biometric & Face Auth: Uses fingerprint, iris scans, or AI face liveness checks for high-security verification.
• Demographic Checks: Validates name, date of birth, gender, and address against government records.
• Offline XML / QR: Processes digitally signed files or QR codes without live server pings.

Transaction & Management Features

• User Consent: Mandatory capture of explicit customer consent prior to data fetching.
• Data Encryption: End-to-end PID (Personal Identity Data) protection during transmission.
• Aadhaar Data Vault: Compliance tool for secure, zero-storage handling of sensitive identification numbers.
• Audit Logging: Tracking transaction logs, response codes, and timestamps for regulatory compliance.

Aadhaar Verification API Scalability & Performance

When implementing or evaluating an Aadhaar Verification API, understanding its scalability and performance parameters is critical for keeping digital onboarding smooth and compliant. Because these Aadhaar authentication APIs interface directly with the Unique Identification Authority of India (UIDAI) database (or through authorized sub-AUAs), they function as the foundational trust layer for India’s digital economy.

Here is a performance and scalability breakdown of enterprise-grade Aadhaar Verification APIs in 2026.

Key Architectural Drivers for Scalability

To handle millions of daily transactions, top-tier Aeps india leverage optimized infrastructure workflows:

• Asynchronous Processing & Queueing: High-volume spikes (e.g., during a major fintech app launch or festival sale) are smoothed out using robust message queues (like Kafka or RabbitMQ) to prevent Aadhaar based eKYC API timeouts.
• Aadhaar Data Vault (ADV) Isolation: Fully compliant infrastructure segregates and isolates the ADV. Since providers must follow a strict zero-storage policy for raw Aadhaar numbers and biometrics, Aadhaar number verification API optimize data pipeline speeds by passing tokens instead of heavy payload data.
• Fallback Verification Modes: To bypass intermittent UIDAI central server slowness or OTP delays, scalable architectures implement alternative verification loops, such as Offline Secure XML or QR-code based scanning. QR-based checks boast near-zero downtime since they do not rely on a live UIDAI handshake for basic validation.
• AI-Driven Extraction: For document OCR extraction, modern systems achieve 98% to 99.9% accuracy rates using intelligent text enhancements. This eliminates manual queue bottlenecks and keeps automated onboarding flowing.

Compliance & Security Overheads

Scaling an Aadhaar KYC API cannot happen at the cost of security. Performance engines must handle the heavy computational overhead of:

• End-to-End Encryption: Encrypting data packets in transit using advanced HSM (Hardware Security Module) protocols.
• Immutable Logs: Logging consent trails and generating audit footprints instantly (processing tens of thousands of immutable logs daily).

Aadhaar Verification API for KYC & Customer Onboarding

An Aadhaar Verification API securely connects a business platform to the Unique Identification Authority of India (UIDAI) central database to instantly validate a customer’s identity for electronic Know Your Customer (eKYC) compliance.

Key Verification Methods

• OTP-Based Authentication: Sends a One-Time Password to the mobile number linked to the user’s Aadhaar for quick consent and validation.
• Biometric Authentication: Uses Aeps fingerprint device or Aeps iris scanner device for high-security applications in banking and finance.
• Demographic Matching: Cross-references provided names, addresses, and dates of birth against existing database entries.
• XML eKYC & OCR: Extracts official data and parses offline digital XML files or physical card images securely.

Benefits for Customer Onboarding

• Speed: Reduces identity check times from weeks or days down to a few seconds.
• Cost Efficiency: Eliminates physical paperwork, manual data entry, and courier overhead.
• Fraud Reduction: Blocks fake identities and duplicate profiles via official government verification.
• Regulatory Compliance: Helps organizations meet mandates set by the RBI, SEBI, and UIDAI.

Aadhaar Verification API vs eKYC API

An Aadhaar Verification API confirms if a specific Aadhaar number is genuine and active, while an Aadhaar eKYC API retrieves a user’s digitally signed demographic data and photograph from UIDAI with their consent to complete a full digital onboarding process.

Core Differences

• Aadhaar Verification API: Validates the existence and status of an Aadhaar number (active or inactive) and can run demographic or OTP/biometric matching to confirm basic validity. It typically returns limited response parameters (such as existence status, state, gender, or age range) without pulling full identity payloads.
• eKYC (Electronic Know Your Customer) API: Pulls full, verified customer profile details directly from the UIDAI central database including the individual’s full name, address, date of birth, and profile photograph authenticated via an Aadhaar-linked OTP or biometric scan.

Comparison Breakdown

Aadhaar Verification API With Other KYC APIs

An Aadhaar Verification API serves as the anchor of the digital identity ecosystem in India, allowing businesses to confirm a customer’s real-time identity against the UIDAI database via methods like OTP, biometrics, or XML. However, for robust financial onboarding, regulatory compliance, and fraud prevention, companies rarely use Aadhaar verification in isolation. Instead, they deploy a comprehensive KYC (Know Your Customer) and KYB (Know Your Business) API stack.

The table below outlines how the Aadhaar Verification API integrate with other critical KYC/KYB APIs to create an end-to-end, automated digital onboarding workflow:

Aadhaar Verification API vs Aadhaar Authentication

An Aadhaar Verification API is the software interface used to programmatically trigger and process Aadhaar Authentication or eKYC requests against the UIDAI Central Database.

Core Differences

• Aadhaar Authentication: The fundamental core process defined by UIDAI where an individual’s identity attributes (OTP, biometrics, or demographic details) are matched against the Central Identities Data Repository (CIDR), returning a simple Yes or No match confirmation without sharing personal data.
• Aadhaar Verification API: The Aadhaar Verification API developer-friendly, programmatic REST/SOAP endpoint wrapper provided by authorized Authentication User Agencies (AUAs) or third-party platforms that allows software applications to execute authentication or pull full encrypted eKYC data (name, address, photo) with explicit user consent.

Comparison Table

Common Aadhaar Verification API Errors & Solutions

When integrating or maintaining an Aadhaar verification flow, handling Aadhaar API exceptions gracefully is critical for a smooth user experience. The UIDAI Central Identities Data Repository (CIDR) surfaces specific, standardized error codes when an authentication or verification request fails.

The most common Aadhaar Verification API errors, their technical meanings, and production-ready solutions are structured below.

1. Demographic & Input Errors (100 – 299)

These errors occur when the submitted user data does not match the record stored in the UIDAI database.

• Error 100 — Demographic Data Mismatch: The personal information (such as Name, Date of Birth, or Gender) provided in the API payload does not match UIDAI records.
  • Solution: Implement strict validation on your frontend. Clean whitespace and trailing characters before submission. For Name matching, consider utilizing a fuzzy matching algorithm pre-submission or instruct users to type their name exactly as it appears on their physical Aadhaar card.
• Error 200 — Address Data Mismatch: The address fields provided in the demographic request do not match.
  • Solution: Switch to Offline Aadhaar XML or DigiLocker-based KYC workflows to pull verified addresses directly instead of matching raw text strings.

2. Biometric & Device Failures (300 – 399)

These occur during fingerprint, iris, or face authentication due to poor capture quality or hardware issues.

• Error 300 — Biometric Data Mismatch: The biometric data (fingerprint/iris/face) captured by the device fails verification against UIDAI’s records.
  • Solution: Ensure your platform relies on L1 biometric devices (which process encryption at the hardware level). Provide visual UI cues instructing the user to clean the scanner glass, wipe their finger, or adjust ambient lighting if utilizing FaceAuth.
• Error 330 / 940 — Biometrics or Aadhaar Locked: The Aadhaar cardholder has locked their biometrics or authentication privileges for security via the mAadhaar app.
  • Solution: Stop retrying immediately. Prompt the user to log into their mAadhaar app or the official UIDAI portal to unlock their biometrics/Aadhaar temporarily. Alternatively, offer Virtual ID (VID) authentication if supported.

3. OTP & Session Failures (400 – 499)

Errors tied to the One-Time Password lifecycle during instant verification.

• Error 400 — Invalid OTP: The OTP entered by the user is incorrect or has expired.
  • Solution: Create a 10-minute countdown clock on the UI. Prevent users from slamming the “Resend” button by enforcing a 60-second cooldown.
• Error 402 — “txn” Mismatch: The transaction ID (txn) used in the authentication request does not match the transaction ID generated during the initial Request OTP API call.
  • Solution: Ensure your backend architecture is stateful or passes the original transaction ID seamlessly from the OTP generation session to the OTP verification session without altering the payload string.

4. Technical, Encryption & Server Errors (500+, 900+)

These point to security protocol issues, improper payload formatting, or downstream UIDAI source downtime.

• Error 511 — Invalid PID XML Format: The structural validation of your PID (Personal Identity Data) XML block failed prior to or after encryption.
  • Solution: Ensure compliance with the UIDAI Auth API 2.0 structure. Validate that your code properly builds the XML schema before passing it to your encryption module.
• Error 512 — Invalid Aadhaar Holder Consent: The resident consent (rc) attribute within the XML payload is missing or set incorrectly.
  • Solution: Hardcode the rc attribute value to “Y” inside your Auth block. Legally, you must explicitly capture user consent on your interface before passing this affirmative flag.
• Error 500 / 930 / 999 — Upstream Server / Technical Failure: General internal network error or sudden CIDR timeout.
  • Solution: Implement exponential backoff retry logic on your backend for 5xx responses. If peak-hour traffic introduces high source latency, orchestrate a fallback routing mechanism to alternative KYC flows (like Video KYC or DigiLocker) to preserve conversion rates.
