"Why can't we do this in a week?" Every CTO hears this when a new integration comes up. With Wix — a new sales channel for Zendrop alongside Shopify, TikTok Shop, and ClickFunnels — we could have built something in a week. It would work in the demo and break in production.
First two weeks: OAuth, product sync, order ingestion, fulfillment callbacks. The remaining two weeks: error handling for undocumented API states, retry logic that doesn't duplicate fulfillment, monitoring so we know when something breaks before merchants do, load testing against real traffic. The CEO's question wasn't really about timeline — it was about whether the extra time was worth it. For a sales channel where failure means merchants lose money and trust, it was.
Four weeks total. Zero incidents since launch. If someone tells you they integrated with a major platform in a week, ask them how the first month in production went.
