The Decision API enables you to make ad requests without using ad code. By posting to a RESTful endpoint, Kevel's ad engine will return decision data and creative contents that can be used to serve ads in your application.
You'll want to set the Content-Type in the header as application/json. (The API will also accept text/plain to support applications that cannot change the content type, such as older versions of IE.)
If the request does not contain a user key, one is automatically generated in the response. UserKeys are important for Frequency Capping and UserDB.
The user key supplied in the
userobject overrides the user key set via the
API Key authentication is not required when making a Decision API request. For added security, Kevel has the option to require API Key authentication. Please reach out to your CSM or [email protected] to enable.
