Fraud Credit Policy


Invalid traffic, while low on our platform due to proactive monitoring, is a legitimate concern for buyers and sellers of digital advertising. As part of the effort to combat this, on March 31st, 2018, Xandr implemented new policies that streamline the refund process for buyers (excluding bidders) who have purchased invalid traffic on our platform.

Buyers who have paid for non-human traffic may submit a claim to Client Finance through client support form according to the following rules:

  • Claims must be submitted for the previous month's activity within 10 days of the month's close (e.g., for March activity, claims must be submitted by April 10th).
    • Buyers should submit one claim covering the entire month's activity.
  • The claim must include reporting from one of the following approved verification partners:
  • Buyers must provide the following information via a report from their verification partner (granularity must be at the monthly level):
    • Placement ID
      • Publisher ID (if working with IAS)
    • Seller member ID
    • Campaign ID
    • Line item ID
    • Total imps
    • Number of invalid imps 
    • % of invalid imps 


Prepare a claim

To participate in this program, you must work with one of the verification partners listed above and complete the following 2 tasks:

  1. Collect the necessary data. To do this, you must first be trafficking a supported tag (from one of our approved verification partners) with your creatives. Please reach out to your verification partner for instructions on how to acquire and implement their product below.
