# Tokens

The Profiles API Token enables your ability to increase personalized content based on detailed customer information. This REST API returns customer data in real-time and updates your segment information. The ability to create a Profiles API token is based on your <a href="https://docs.treasuredata.com/display/public/PD/Folder-based+Permissions">folder permissions.</a> <br> <br> You can also use Profiles API Token to personalize your customers' experience on your website. You can combine Treasure Data’s personalization feature with A/B Testing tools such as Adobe Target, Optimizely, or Google Optimize, to determine the version of your website that yields results. <br> <br> When the underlying personalization workflow completes, the personalization data set is refreshed. You can see a current list of the segments to which a specific profile belongs. You can also see a list of attributes associated with the specific profile.<br> <br> The parent segment must already exist. The parent segment is the basis for all data accessed by Profiles API Tokens. <br> <br> The use of the Profiles API Token with your tools requires the use of the Treasure Data JavaScript SDK and support or services consultation.
