Platform Integration Patterns: Connecting External Systems

Modern platforms integrate with dozens of partners and systems. Here are proven patterns to keep integrations reliable and maintainable.

Patterns overview

• Synchronous APIs for request/response needs
• Event-driven integrations for decoupling and scaling
• Bulk data exchange for nightly or hourly sync

Reliability

• Retries with idempotency keys
• Dead-letter handling and reconciliation jobs
• Contract testing for adapters

Security

• mTLS, OAuth 2.0, and fine-grained scopes
• Payload validation and schema enforcement

Observability

• Correlation IDs across boundaries
• Integration health dashboards and SLAs

FAQs

What pattern should we default to? Prefer events for decoupling; supplement with APIs for reads and commands.

How do we detect silent failures? Use end-to-end reconciliation jobs and alert on drift.

Conclusion

The right mix of APIs, events, and data syncs creates resilient, evolvable integrations. Ready to accelerate your digital transformation?
