Below are some examples of how to extend payload to use different settings in the campaign.

Budget / App Diversity

For CPM/CPC campaigns (campaign_type is cpm or cpc)

"optimization": {
    "app_diversity": "on",
    "app_budget_percentage": "25"
}

For CPI campaigns (campaign_type is cpi, cpi_alpha or cpa_rt)

"optimization": {
    "app_diversity": "on",
    "app_budget_percentage": "11",
    "cpi_algo_state_allowed": "exploit"
}

Targeting > Platform (OS Version targeting)

Targeting All OS Versions for Android:

{
  "targeting": {
    "os_versions": {
      "type": "all",
      "versions": [
        {"os_id": 11, "values": [{ "min": 0, "max": 999999999 }]}
      ]
    }
  }
}

Possible values for os_id are:

3 if need to target iOS and Android. You cannot use this value if Order has Mobile Object.
11 when targeting Android
12 when targeting iOS.

Range of OS Version

{
  "targeting": {
    "os_versions": {
      "type": "range",
      "versions": [
        { "os_id": 11, "values": [ { "min": 131, "max": 134 } ] }
      ]
    }
  }
}

All items in values must be IDs from OS Versions.

Specific OS Versions

{
  "targeting": {
    "os_versions": {
      "type": "specific",
      "versions": [
        { "os_id": 11, "values": [ 134, 90 ] }
      ]
    }
  }
}

All items in values must be IDs from OS Versions.

Targeting > Smart App Categories

{
  "targeting": {
    "taxons": [
      {"category_id": 17, "genre_id": 3, "subgenre_id": 3},
      {"category_id": 15, "genre_id": 25, "subgenre_id": 79},
      {"category_id": 12, "genre_id": 41, "subgenre_id": 3}
    ]
  }
}

Value 3 means "all". In above example

{"category_id": 17, "genre_id": 3, "subgenre_id": 3} we are targeting all genres of category with id 17,
{"category_id": 12, "genre_id": 41, "subgenre_id": 3} - target all subgenres of genre with id 41.

Use List Smart App Categories API to get list of possible values.
