Segment Pixel Tracking API

The Segment Pixel Tracking API provides a way to collect analytics data using image pixel requests, which is useful in environments where JavaScript cannot execute, such as email clients. It supports identify, track, page, screen, group, and alias calls through pixel endpoints under the api.segment.io domain. This API is particularly suited for tracking email opens, ad impressions, and other contexts where embedding a tracking pixel is the only viable data collection method.
