Frequently Asked Questions

What is the Chequedb API?

The Chequedb API is a RESTful API that enables developers to integrate check processing into their own applications. It provides endpoints for check image upload, OCR data extraction (payee, amount, date, MICR line), fraud detection, signature verification, and deposit processing. Real-time webhooks notify your application of status changes. The API supports both cloud-hosted and on-premise deployments.

How do I get started with the Chequedb API?

Start with the bank check OCR API overview, then move into the integration docs on this page. Chequedb provides a sandbox environment for testing with sample check data, so you can validate your integration before going live. Native SDKs for iOS, Android, and Web accelerate development with pre-built UI components and helper functions.

What SDKs does Chequedb provide?

Chequedb provides native SDKs for iOS (Swift), Android (Kotlin/Java), and Web (JavaScript/TypeScript). Each SDK includes pre-built UI components for cheque capture, camera integration with automatic edge detection, image quality optimisation, and offline capabilities. SDKs handle the complete capture flow including guided image capture, quality validation, and real-time feedback to users.

Is the Chequedb API secure and compliant?

Yes. The Chequedb API is SOC 2 Type II certified, PCI DSS Level 1 compliant, ISO 27001 certified, and GDPR compliant. All data is encrypted in transit using TLS 1.3 and at rest with AES-256. Authentication supports OAuth 2.0 and API key methods, with fine-grained access controls and comprehensive audit logging. IP whitelisting and rate limiting provide additional security layers.

What are the Chequedb API rate limits?

Rate limits scale by plan: Starter plans include 100 requests per minute, Pro plans offer 1,000 requests per minute, and Enterprise plans provide custom limits to match your volume requirements. The API uses token bucket algorithms that allow burst capacity when needed. Enterprise customers can also access dedicated infrastructure for guaranteed throughput.

Can the Chequedb API be used for mobile cheque deposit?

Yes. The API and mobile SDKs are the foundation of Chequedb's mobile check deposit solution. Banks and fintechs use the SDK to embed check deposit directly into their mobile apps, or use the API to build custom deposit flows. The SDKs support iOS 13+, Android 8.0+, and modern web browsers, with features like guided image capture, automatic quality checks, and real-time status updates.
