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. title: Decision APIs version: v0.2.2 x-logo: altText: A2 Logo url: >- https://cdn.prod.website-files.com/668de9e1f25ab5675d87758d/6690cf1bdce95af5e3522c25_a2_logo_800_250.png servers: [] security: [] tags: - description: > Ad Serving APIs for requesting ads and configuring cache settings and other parameters of the ad serving modules. name: Ad Serving - description: >- APIs for manipulating caches of the serving server. ### **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**. name: Cache Management - description: |- APIs for manipulating configurations of the serving server name: Configuration - description: > APIs for receiving ad conversion, impression, and click logs — essential for tracking and optimizing advertisement performance. name: Ad Serving paths: /dmp/v0/log/activity: post: tags: - Activity Log summary: Record Activity Log description: >- Records user activity logs for advertising optimization and analytics.

string - 'null' ua: description: >- Browser user agent string. This field represents a raw user agent string from the browser. For backwards compatibility, exchanges are recommended to always populate ‘ua’ with the User-Agent string, when available from the end user’s device, even if an alternative representation, such as the User-Agent Client-Hints, is available and is used to populate ‘sua’. No inferred or approximated user agents are expected in this field. If a client supports User-Agent Client Hints, and ‘sua’ field is present, bidders are recommended to rely on ‘sua’ for detecting device type, browser type and version and other purposes that rely on the user agent information, and ignore ‘ua’ field. This is because the ‘ua’ may contain a frozen or reduced user agent string. type: - string - 'null' type: object Revenue: properties: currency: description: The currency code for the transaction (e.g., 'USD', 'KRW') type: string revenue: description: The monetary amount of the transaction format: int64 type: integer required: - currency - revenue type: object Geo: properties: accuracy: format: int32 type: - integer - 'null' city: type: - string - 'null' country: type: - string - 'null' ext: true ipservice: anyOf: - $ref: '#/components/schemas/IpLocationService' - type: 'null' lastfix: format: uint32 minimum: 0 type: - integer - 'null' lat: format: float type: - number - 'null' lon: format: float type: - number - 'null' metro: type: - string - 'null' region: type: - string - 'null' regionfips104: type: - string - 'null' type: anyOf: - $ref: '#/components/schemas/LocationType' - type: 'null' utcoffset: format: int32 type: - integer - 'null' zip: type: - string - 'null' type: object IpLocationService: enum: - 1 - 2 - 3 - 4 type: integer LocationType: enum: - 1 - 2 - 3 type: integer ````
