The Native Object defines the native advertising opportunity available for bid via this bid request. It will be included as a JSON-encoded string in the bid request's imp.native field or as a direct JSON object, depending on the choice of the exchange. While OpenRTB 2.3/2.4 supports only JSON-encoded strings, many exchanges have implemented a formal object. Check with your integration docs. The Default column dictates how optional parameters should be interpreted if explicit values are not provided.
The main container object for each asset requested or supported by Exchange on behalf of the rendering client. Any object that is required is to be flagged as such. Only one of the {title,img,video,data} objects should be present in each object. All others should be null/absent. The id is to be unique within the AssetObject array so that the response can be aligned.
The Image object to be used for all image elements of the Native ad such as Icons, Main Image, etc. Recommended sizes and aspect ratios are included in the Image Asset Types section.
The video object to be used for all video elements supported in the Native Ad. This corresponds to the Video object of OpenRTB. Exchange implementers can impose their own specific restrictions. Here are the required attributes of the Video Object. For optional attributes please refer to OpenRTB.
The Data Object is to be used for all non-core elements of the native unit such as Brand Name, Ratings, Review Count, Stars, Download count, descriptions etc. It is also generic for future native elements not contemplated at the time of the writing of this document. In some cases, additional recommendations are also included in the Data Asset Types table.

Used for 'call to action' assets, or other links from the Native ad. This Object should be associated to its peer object in the parent Asset Object or as the master link in the top level Native Ad response object. When that peer object is activated (clicked) the action should take the user to the location of the link.
