# Webtrekk: Audience API v2

**08 Nov 2019** Audience API allows you to link Webtrekk to your onsite personalization systems. With this release, we added a second version of it.

Audience API v2 delivers more specific error messages compared to v1 in the following cases:

- There is no cookie available
- The Audience API placement could not be found

Use Audience API v1 or Audience API v2 depending on your need for differentiation of the above-mentioned error cases.
