API integration connects different software systems by enabling them to communicate and share data through Application Programming Interfaces. Whether connecting a payment gateway (Razorpay), sending SMS (Twilio), or syncing data with a CRM (Salesforce), API integration is how modern applications work together to deliver comprehensive functionality.
Key Points
- Types: REST APIs, GraphQL, WebSocket, SOAP (legacy)
- Authentication: API keys, OAuth 2.0, JWT tokens
- Common integrations: payment (Razorpay, Stripe), SMS (Twilio, MSG91), email (SendGrid), maps (Google Maps)
- Error handling, rate limiting, and retry logic are essential for reliable integrations

Frequently Asked Questions
Payment: Razorpay, Cashfree, PhonePe. Communication: MSG91, Twilio (SMS/WhatsApp), SendGrid (email). Identity: Aadhaar verification, PAN verification. Maps: Google Maps, MapMyIndia. Analytics: Google Analytics, Mixpanel. Storage: AWS S3, Cloudflare R2. These cover most integration needs for Indian applications.
Implement retry logic with exponential backoff, circuit breaker pattern for persistent failures, timeout handling, fallback behaviour for non-critical integrations, comprehensive error logging, and monitoring/alerting. For payment APIs specifically, implement idempotency keys to prevent duplicate charges during retries.
