Buying Native Inventory
Xandr provides access to a number of native supply sources. While you can set up individual profiles for each source, we recommend that you set up a single profile to reach all of them simultaneously. This type of setup allows for easier budgeting, reporting, performance-tracking, frequency capping, etc. This page describes the process of setting up a profile to serve across whichever native sellers you choose.
For specific information on individual sellers, see Native Inventory Seller Specifications.
Step 1. Ensure You Are Whitelisted by Native Sellers
Some native sellers require you to go through a quick buyer audit before they'll grant access to their inventory. Here is a list of sellers and their whitelist requirements:
|Native Seller (ID)||Are you whitelisted?||How to become whitelisted|
|Ligatus (3723)||You must be whitelisted to buy Ligatus inventory.||Please reach out to email@example.com for whitelist approval.|
Sanoma Finland (7458)
|You must be whitelisted to buy Sanoma Finland.||Please reach out to firstname.lastname@example.org.|
The following sellers do not currently have any whitelist requirements:
- Figaro Medias
- Schibsted Norway
Step 2. Upload Native Creatives
To maximize reach for your creatives across native inventory sources, here are some general guidelines we recommend:
|Creative Service Field||Xandr Guidelines|
|Use template ID 39461|
|Create a native_attribute object|
|25 character maximum|
|300 character maximum|
|1:1 aspect ratio|
|1.91:1 aspect ratio|
200 KB max)
|25 character maximum (brand of advertisement)|
If a parameter is not mentioned in the table above, enter whatever values make sense for your profile.

Step 3. Profile Setup
To receive a native bid request, you must include a creative size of 1x1 in the size_targets field of the Legacy Bidder Profile Service.
