// Build
API integrations that fail gracefully — not silently
Custom REST and GraphQL API development, third-party integrations, payment gateways, CRM/ERP connectors, and webhook automation. Built with retry logic, circuit breakers, and monitoring that make your integrations as reliable as your core product.

Custom API Development
OpenAPI-first REST and GraphQL API design and build.
Third-Party API Integrations
Reliable integration with Stripe, Twilio, HubSpot, and more.
Payment Gateway Integration
Stripe, Razorpay, PayU — subscriptions and one-time payments.
CRM & ERP Integrations
Salesforce, HubSpot, SAP, and NetSuite integrations.
Webhooks & Automation Integrations
Event-driven integrations with reliable delivery.
// Standards
Integration engineering standards
Reliability by design
Retry logic, circuit breakers, idempotency keys, and dead letter queues — integrations designed to handle failures gracefully, not ignore them.
Security baseline
OAuth 2.0 or JWT authentication, input validation, rate limiting, HTTPS enforcement, and no credentials in code or logs.
OpenAPI documentation
Every custom API is documented with OpenAPI 3.0 — machine-readable specifications that enable client SDK generation and API portal publication.
Tested at failure modes
Integration tests cover error scenarios — API timeouts, 4xx errors, schema drift, and rate limit responses — not just happy paths.
Monitored in production
Error rates, latency percentiles, and integration health metrics are monitored and alerted from day one.
Dependency isolation
Third-party APIs are wrapped in adapter layers that prevent their failures or schema changes from cascading into your core product.

Common questions about API integrations
What is the difference between REST and GraphQL?+
REST uses predefined resource endpoints — simple, cacheable, and well-understood. GraphQL uses a single endpoint with flexible queries — better for complex data relationships and multiple clients with different data needs. We recommend based on your specific access patterns.
How do you handle third-party API outages?+
Circuit breakers detect and isolate failing third-party services, preventing cascading failures. Retry logic with exponential backoff handles transient failures. Fallback responses ensure graceful degradation when services are unavailable.
What payment gateways do you integrate with?+
Stripe, Razorpay, PayU, Cashfree, and PayPal for most engagements. We also integrate with regional gateways as needed. For Indian businesses, Razorpay or Cashfree for UPI/NEFT support alongside cards.
Can you integrate with SAP or legacy ERP systems?+
Yes — SAP BAPI, RFC, and OData APIs; NetSuite SuiteScript and REST; Oracle ERP APIs. ERP integration is complex but we have delivered it successfully across multiple enterprise engagements.
How do you secure webhook endpoints?+
HMAC-SHA256 signature verification on every incoming webhook ensures the request is from the expected source. We implement idempotency to prevent duplicate processing of retried webhooks.
