    ### Introduction

    The Decision API is responsible for selecting and distributing ads or
    content based on user requests or contextual information, all in real time.

    Its rapid response and dynamic capabilities enable the **optimal** ad or
    recommendation to be served, ensuring users receive the highest possible
    value.


    A variety of algorithms, machine learning models, and rule-based logic can
    be applied, allowing the system to **adapt flexibly** to constantly changing
    conditions.

      ### **Important**

      If you directly manipulate the cached data related to advertising or
      recommendations on the Serving server,

      we **strongly advise** against also modifying the advertising or
      recommendation data through the Ad Manager.


      Alternatively, we **recommend** handling any advertising or recommendation
      data modifications via the Ad Manager APIs.

      Any changes made on the Serving server will **not** be reflected in the Ad
      Manager,

      which can compromise **data integrity**.
