Optimizely Attributes API lets you manage the custom attributes used for audience targeting and segmentation. It is part of the Optimizely REST API (base URL https://api.optimizely.com/v2), so teams running experiments and personalization on the Optimizely platform can create and maintain the attributes that define who sees what. Typical users are developers, experimentation engineers and marketing technologists who want to keep targeting data in step with their own systems.
