Authentication requests

Epsilon Retail Media's documentation is now centralized with our knowledgebase!

For up to date guides, please view this page in the new Partner APIs space of our documentation.

Epsilon Retail Media uses the User Key method for authenticating API requests. You can also retrieve the User Key through the Retrieve user key API, which serves as an alternate method to obtain the User Key from user settings. The Retrieve user key API allows partners to generate an authentication key by providing a valid username and password.

User key

In the Epsilon Retail Media platform, advertisers can find their user key in the User Settings section. This key is unique to a user level, and can be integrated into your application to manage authentication with the Epsilon Retail Media system.
