Integrations are how operations actually run: TMS + ELD, accounting, visibility, messaging, and customer portals. A good API makes those connections reliable, not fragile.
Start with fundamentals: consistent resource models, clear error responses, and versioning so customers can upgrade on their timeline.
Idempotency is critical for write operations. Networks fail, retries happen, and duplicate writes are expensive in logistics.
Rate limits are not just “security”—they protect both sides from cascading failures and help teams plan usage responsibly.
Ship integrations with auditability in mind: trace IDs, timestamps, and a way to reconcile what was sent versus what was accepted.
When APIs are treated like product surface area (docs, examples, clear contracts), integration work gets faster and support tickets go down.
