Cookie

_br_uid_2 parameter

The _br_uid_2 cookie is a first-party cookie created by the Bloomreach tracking pixel library (BrTrk). This cookie creates a unique, anonymous identifier for every browser or device. It’s important to include this cookie in all of your API requests because it is used to power several features such as Testing, Targeting and 1:1 User Personalization.

Exception: Organic widgets and HTML-powered thematic searches. 

These Organic API requests don't use the _br_uid_2 cookie:

  • Related categories, related items and related products widgets
  • Thematic pages with HTML responses

Example of the cookie in an API call
