What Reliable API Integrations Have in Common
Reliable integrations are rarely impressive on the surface. They are just disciplined.
The baseline
The basics matter:
- idempotent operations where possible
- retry logic with sensible limits
- validation before writes
- explicit sync status
- alerts when a step fails silently
What breaks systems
Most integration failures come from assumptions that stop being true:
- field names change
- rate limits appear
- an empty value gets treated as valid
- one system updates faster than the other
What scales better
Integrations scale better when they have:
- a clear source of truth
- status tracking per record
- a queue between unstable steps
- auditability for business-critical changes
Good integrations are not just connected. They are recoverable.
