S-05 / System Integration & API Engineering
Make the systems you already have work together.
A reliable integration does more than move a payload from one endpoint to another. It has to authenticate correctly, survive retries, avoid duplicate business actions, expose failures, preserve traceability and make reconciliation possible when systems disagree.
What is system integration?
System integration connects separate applications so that data and business events can move between them reliably. A robust integration defines ownership, identity, authentication, event semantics, retries, idempotency, monitoring and recovery — not only the API payload.

Design
Design questions we settle early
- Which system owns each field and state?
- Can the same event arrive twice?
- Can events arrive out of order?
- What does deletion mean across systems?
- How are credentials rotated or revoked?
- What happens if one system is unavailable for hours?
- How does support identify and replay a failed exchange?
- How can we prove what was sent and accepted?
Next step
Have systems that do not talk to each other?
Tell us which systems are involved, who owns each part of the workflow, and where information is copied or reconciled by hand today.
