How do I get started?

To get started (whether as a publisher, a PubMatic partner or as an individual developer), you need to go go through the registration process. Click on the following link to register:

  • If you are a publisher, you need to submit your Publisher ID on the PubMatic platform.
  • If you are a developer, you need to provide your Github profile ID and LinkedIn profile ID, if it exists, to speed up your profile activation.
  • If you are a partner, you need to provide the name of the Referral person at PubMatic to speed up your profile activation.

All API methods are available in this portal, and there is comprehensive documentation explaining all aspects for using and deploying these methods. Click here for the API documentation:
