Integration Development

Why Integration Is Hard

Third-party integrations are often treated as simple tasks but routinely become sources of production incidents. API rate limits, schema changes without notice, authentication edge cases, partial failures, and retry logic all require careful engineering. Software Brothers builds integrations that are robust by design — not brittle by default.

Types of Integrations We Build

• REST & GraphQL API Integrations — Clean, maintainable API clients with proper error handling, retry logic, and rate limit management.
• Payment Processing — Stripe, PayPal, Adyen, and custom payment gateway integrations with PCI DSS considerations.
• ERP & CRM Integration — Salesforce, HubSpot, SAP, and Microsoft Dynamics — bidirectional data sync with conflict resolution.
• Communication & Notifications — Email (SendGrid, SES), SMS (Twilio), push notifications, and Slack/Teams webhook integrations.
• Logistics & Supply Chain — Carrier APIs, warehouse management systems, and real-time shipment tracking integrations.
• Webhook Platforms — Outbound webhook systems that allow your customers to integrate with your product reliably.

Our Integration Engineering Principles

• → Idempotency — every integration handles duplicate events and retries without double-processing.
• → Circuit breakers — third-party failures degrade gracefully without cascading into your core system.
• → Schema versioning — we design for breaking changes in third-party APIs so updates don't cause outages.
• → Observability — every integration is instrumented with latency metrics, error rates, and alerting.
• → Testing with mocks — comprehensive test suites that run without live third-party connections in CI.
