In August 2025, Greg Losier updated the Customer.io Destination Documentation in the segmentio/segment-docs repository, focusing on improving onboarding and integration reliability. He enhanced the documentation using Markdown, adding new visuals and revising API guidance to include detailed rate-limit information. Greg clarified the process for obtaining API credentials and provided actionable advice on managing data ingestion rates to help users avoid throttling. His work centered on documentation quality, emphasizing clear communication and developer experience rather than bug fixes. The update addressed common integration pain points, resulting in more accessible and reliable guidance for developers working with Customer.io and Segment APIs.
