Integrating AI-powered document processing into your applications can transform user experience and operational efficiency. This comprehensive guide walks developers through implementing BankStatementFlow's API, from authentication to advanced features.
Getting Started with the API
Authentication
BankStatementFlow uses API key authentication with optional OAuth 2.0 for enhanced security:
// Basic API Key Authentication
const headers = {
'Authorization': 'Bearer YOUR_API_KEY',
'Content-Type': 'application/json'
};Base URL and Versioning
All API endpoints use the base URL: https://api.bankstatementflow.com/v1/
The API uses semantic versioning with backwards compatibility guaranteed within major versions.
Core API Endpoints
Document Upload and Processing
The primary endpoint for document processing:
POST /documents/process
const formData = new FormData();
formData.append('file', fileInput.files[0]);
formData.append('document_type', 'bank_statement');
formData.append('output_format', 'json');
const response = await fetch('https://api.bankstatementflow.com/v1/documents/process', {
method: 'POST',
headers: { 'Authorization': 'Bearer YOUR_API_KEY' },
body: formData
});Security Best Practices
API Key Management
- Store API keys in environment variables
- Use different keys for development and production
- Implement key rotation policies
- Monitor API key usage and set alerts
Data Protection
- Always use HTTPS for API calls
- Implement request signing for sensitive operations
- Validate webhook signatures
- Use temporary URLs for file uploads when possible
This guide provides the foundation for integrating BankStatementFlow's API into your applications. The API's flexibility and robust feature set enable developers to build sophisticated document processing workflows that scale with business needs.
