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 firstname.lastname@example.org for whitelist approval.|
Sanoma Finland (7458)
|You must be whitelisted to buy Sanoma Finland.||Please reach out to email@example.com.|
|Taboola (3364)||You must be whitelisted to buy Taboola inventory.||Reach out to your account owner or to customer support and provide countries of interest and the type of advertising you're planning on running (content / direct response / brand) with example brands.|
|TripleLift (1314)||If you have not previously bought TripleLift via Xandr, you are not yet whitelisted.||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)

If a parameter is not mentioned in the table above, enter whatever values make sense for your profile.
