API integration: making systems talk
An API lets two systems exchange data automatically, so you stop copying information by hand between apps. Good integration means data flows from a single source of truth with clear rules for what syncs when. The integration quality, not the interface, decides whether people trust it.
What an API does
A defined way for systems to send and receive data without manual steps.
One source of truth
Decide which system owns each field and sync one way, so records do not conflict.
Reliability first
Handle errors and retries - a flaky integration is worse than none.
FAQ
Do all systems have APIs?
Most modern ones do; older systems may need a connector.
Real-time or scheduled?
Real-time for urgent data, scheduled for the rest.
What breaks integrations?
Undefined ownership and silent failures - build in error handling.
