Customer churn is the percentage of users who stop using an API during a defined period. It is the opposite of retention and indicates declining product stickiness. section 11.1.3
Measure churn alongside related API retention signals:
- Track recurring API call volume daily, weekly, or monthly to identify usage trends. section 11.1.3
- Group users into cohorts by the date of their first request, then monitor repeat requests over seven- or 30-day windows. section 11.1.3
- Compare users who continue making requests with those who stop to evaluate API loyalty and product stickiness. section 11.1.3
