Buyer APIs

About Buyer APIs

Buyers use PubMatic APIs to create, manage, discover, and negotiate buying decisions in the PubMatic system. You'll find the supporting documentation for PubMatic's Buyer APIs here.

All PubMatic APIs require the use of an API token. If you don't have a token, get one now.
