API Integration

An API integration is a connection between two software systems that lets them exchange data automatically — a website sending orders to an accounting system, a CRM pushing contacts into an email platform.

The cost is rarely in the connection itself. It's in the mismatches: two systems that model a "customer" differently, rate limits that force batching, authentication that expires, and fields one side requires that the other doesn't have.

Rate limits deserve specific attention because they're invisible in testing and decisive in production. An integration that works fine on ten records may take days on forty thousand, and needs batching and backoff designed in from the start.

Why it matters

When an integration quote seems high for "just connecting two systems," the difference is usually error handling, rate limits and data reconciliation — the parts that determine whether it still works in six months.
