API Integration
From payment gateways to CRM integrations, we have connected hundreds of third-party APIs and made disparate systems communicate seamlessly. We handle complex authentication flows, rate limiting strategies, webhook management, and robust error recovery to ensure your integrations are reliable and maintainable. Our API integration expertise includes integrating payment processors like Stripe, PayPal, and Razorpay, connecting CRM systems such as Salesforce and HubSpot, implementing marketing automation tools, building custom middleware for legacy system integration, and creating unified API gateways that abstract multiple services.
We design integrations with proper retry logic, circuit breakers, and monitoring so you can trust your systems to work together reliably. Whether you need to connect a few services or build a comprehensive integration platform, we deliver solutions that just work.

Our Process
A proven approach to delivering excellence at every stage of your project.
Integration Requirements Analysis
We start by understanding exactly what data needs to flow between systems and how frequently. We map out your integration requirements, identify data transformation needs, document business rules, and establish success criteria. This phase includes stakeholder interviews, reviewing existing system documentation, and creating a comprehensive integration specification that serves as the blueprint for implementation.
API Documentation Review
We thoroughly study the APIs you need to integrate - their endpoints, data formats, rate limits, authentication methods, and quirks. We create test environments to experiment with the APIs, validate assumptions, identify potential issues, and understand edge cases. This deep dive ensures we design integrations that handle all scenarios gracefully, from happy paths to error conditions.
Authentication Implementation
Modern APIs use various authentication methods: OAuth 2.0, API keys, JWT tokens, HMAC signatures, or mutual TLS. We implement robust authentication that securely manages credentials, handles token refresh automatically, supports multiple environments (dev, staging, production), and includes proper secret management using tools like AWS Secrets Manager or HashiCorp Vault. We ensure your integration credentials are never exposed in logs or code.
Error Handling and Retry Logic
Networks fail, APIs go down, and rate limits get hit - we design integrations that handle these realities gracefully. We implement exponential backoff for retries, circuit breakers to prevent cascading failures, dead letter queues for failed messages, idempotency to handle duplicate requests, and comprehensive logging for debugging. Your integrations will recover automatically from transient failures and alert you only when human intervention is needed.
Monitoring and Alerting Setup
We set up comprehensive monitoring for your integrations: tracking success rates, response times, error patterns, and data volume. Using tools like Datadog, New Relic, or CloudWatch, we create dashboards that show integration health at a glance and configure intelligent alerts that notify you of issues before they impact users. We also implement audit logs for compliance and debugging, ensuring you have complete visibility into what data flows through your systems.
