Legacy Stats API

This article details how to use the old Statistics API. If you're using the new Campaigns dashboard, please refer to the documentation on the new Statistics API.

Unity Ads provides an API for Publishers and Advertisers to retrieve monetization and acquisition statistics data directly in CSV format. The Unity Ads Statistics API can used to retrieve the game and campaign data for loading them up to partners own reporting system periodically. In practice, the statistics API is a machine-to-machine interface for fetching the same statistics files that have been available in the Unity Ads Admin Panel automatically.


The statistics API works in two stages: First, the user performs an GET request to an authentication server which, after a successful authentication, responds with a 302 HTTP redirect message. This response contains a the final URL to the statistics server.

Next, when the user performs an GET request to the signed URL, the located server will respond with the requested data in CSV format in the body of the message:

Date,Target campaign id,Target name,clicks
2013-02-28 00:00:00,"5065e1f1fdeb285e4d0430ce","Campaign 1",129
2013-02-28 00:00:00,"50ed569d57fe1e324415fbf7","Campaign 2",428
2013-02-28 00:00:00,"50eeb7c39610c9d21c0225cb","Campaign 3",812
2013-02-28 00:00:00,"511e5f7a73452a3363062d5d","Campaign 4",130


In order to use the Unity Ads Statistics API, you need to get the API key from the Unity Ads Admin Panel. The API key is located in the Account Settings page.

The API key needs to be placed in the authentication request to the apikey HTTP GET parameter.

After a successfull authentication the server will respond with a 302 HTTP-redirect message with the data URL to the statistics server located in the Location HTTP-header. The real data is fetched from this given redirect URL. This is a standard HTTP behavior and is supported by all HTTP clients. For example curl -L "" will directly output the file to the console.

The statistics server always requires signed URLs and will not work if accessed without a valid signature. If the authentication fails, the authentication server will respond with an HTTP/1.1 200 OK header with an error message in the body:

{"error":"Authentication error","responseCode":500,"status":"error"}

Request Format

Monetization statistics (Use this API to get statistics from your monetising games)

See separate document about monetisation stats API here: Unity Ads statistics API for monetisation

Acquisition statistics (Use this API to get statistics from your advertising campaigns)

The acquisition statistics API is similar to the monetization one and supports the following request format:<apikey>&fields=<fields>[&splitBy=<splitbyfields>][&scale=<scale>][&start=<startDate>][&end=<endDate>]([&targetIds=<targetIds>]|[&campaigns=<campaignIds>]


  • <apikey>: the api authentication key retrieved from the Unity Ads Admin Panel
  • <fields>: a comma separated list of available fields:
    • started: number of impressions recorded
    • views: number of completed views recorded
    • clicks: number of clicks recorded
    • installs: number of installs recorded
    • spend: how much money was spent

The default set of fields is all of the above: "clicks,installs,spend".

  • <splitbyfields> contains a comma-separated list of dimension in which to split the data:
    • target – the data is split by target games
    • campaign – the data is split by campaigns
    • country – the data is split by users’ country

The default split by is country. If you don’t want to split the data at all you can write splitBy=none. Either target or campaign split is allowed at the same time. Both can be used with or without country split.

Note: Splitting the statistics data across multiple dimensions at the same time grows the data size exponentially. The processing time might end up being too long and cause the request to fail. All the requests taking more than a minute to generate the data will be terminated at 60 seconds.

  • <scale> – contains the time resolution of the data. Each day is split at 00:00 UTC. The available values for scale are:
    • all – removes time resolution completely and provides the total sum of values within the defined period
    • hour
    • day
    • week
    • month
    • quarter
    • year

The default is day.

  • <startDate> & <endDate> – contains the start (inclusive) and end (exclusive) times for the data. The dates are accepted in following formats:
    • negative numbers are treated as days relative to the current date. For example: -7 is a week ago.
    • Date string in ISO format YYYY-MM-DDTHH:mm:SS:hhhZ, for example: 2013-02-01T14:00:00.000Z

The default start date is -7 and end date is 0 to get the past week’s data.

Note: The start and end dates will be rounded upwards to next full hour. For example, the 14:00:05.000Z will be rounded to 15:00:00.000Z. Also note that if using scale day, using non-midnight <startDate> & <endDate> will still select the range per hour and not the whole day.

  • <targetIds> – comma separated list of target game ids to filter the results. By default, all the games of the advertiser will be included.
  • <campaigns> – comma separated list of campaign ids to filter the results. By default, all the campaigns of the advertiser will be included.

    Note: The results can be filtered by either target games or campaigns, but not both at the same time.


curl -L ",country&fields=views,clicks&start=-31&scale=all&targetIds=8234,7432"

Response Format

CSV format in general

The statistics server will output the requested statistics data in the HTTP response body. The data is in CSV format. Comma ‘,’ is used as the field separator and dot ‘.’ as the decimal separator. Text fields will have double quotes (‘”‘) around them. Pure integer fields don’t have double quotes, but decimal numbers (such as revenue and spend) are doublequoted. The unix newline character (0x0D) is used as the line separator. The first line of the output will contain the field names.


The leftmost field is always the Date. The date is in ISO format YYYY-MM-DD HH:mm:SS.

The next fields are the split dimensions (if selected) in the following order:

  • For target splitted data, two fields "Target game id" and "Target name" will be shown.
  • For campaign splitted data, two fields "Target campaign id" and "Target name" will be shown.
  • For country splitted data, two fields "Country code" and "Country tier" will be shown. Country code is the ISO 3166-1 alpha-2 country codes in upper case based the users’ GeoIP data. "--" is shown for those user IPs whose GeoIP location was unknown. - - The country tier is an integer denoting country’s classification in Applifier’s tier structure.

The rightmost fields are the data fields requested in the same order as in the request.

For example:

$ curl -L ",campaign"
Date,Target campaign id,Target name,Country code,Country tier,clicks,installs,spend
2013-03-01 00:00:00,"50ed569d57fe1f324a15fbf7","Campaign #5","AU",2,71,30,"45.00"
