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.
