The point-to-point trap
Every new connection between two systems adds fragility. Multiply that across a growing enterprise and you get a web no one can safely change.
A stable internal contract
By putting a typed, versioned API in front of your systems, you decouple change. Swap a payment provider without touching core code. Add a channel without rewiring everything.
Observability is non-negotiable
Retries, idempotency, and full tracing turn integration from a black box into something you can actually operate.
