# Overview

> Use Cashfree Secure ID REST APIs to verify identities, documents, and bank accounts in real time with webhooks, SDKs, and bulk processing support.

The Secure ID APIs provide RESTful endpoints for identity verification and document authentication with industry-leading success rates and highly optimised latency. These APIs support both sandbox testing and production environments, determined by your credentials, with consistent authentication and error handling across all endpoints. Real-time webhooks and SDKs ensure seamless integration with sub-second response times for critical verification workflows, including bulk processing capabilities for high-volume verification requirements.

## Key features

The key features offered by Cashfree's Secure ID APIs are:

* **Identity verification**: Verify PAN, GSTIN, DigiLocker, and other government documents in real-time.
* **Document OCR**: Extract and verify information from 8+ official documents including PAN, Aadhaar, Driving License, Passport, Voter ID, Vehicle RC, and more using Smart OCR technology with E-sign integration for document authentication.
* **Biometric verification**: Perform face liveness checks, face matching, and name matching for enhanced security.
* **Bulk processing**: Handle large-volume verification requests efficiently with batch processing capabilities for enterprise-scale operations.
* **Seamless onboarding**: 1-click onboarding solutions with mobile-based data retrieval and automated form pre-filling from verified sources through APIs and SDKs.
* **Location verification**: IP verification, reverse geocoding, and address validation tools for accurate location-based authentication.
