We rebuilt the onboarding flow around a single measurable goal: time-to-first-successful-call. That meant a pre-configured quickstart with sample credentials, a redesigned documentation structure organized by task rather than API reference alphabetically, and an interactive code sandbox letting developers see a working call before writing any code of their own.

We instrumented the entire funnel to see exactly where developers were dropping off, which revealed that a confusing authentication step — not the API’s actual complexity — was the single largest source of abandonment, and fixed that first before investing further in the broader documentation redesign.
