Get results for a single Experiment

experiment_idinteger<int64>The ID for the Experiment you want results for

baseline_variation_idstring<int64>The ID of the variation to use as the baseline to compare against other variations. Defaults to the first variation if not provided. For an experience in a personalization campaign, the value can also be the string 'holdback'.

start_timestring<date-time>The start time of the time interval (beginning time included) used to calculate the results over. If unspecified, defaults to the time that the Experiment was first activated. The start time will be rounded the smallest time modulo 5 minutes larger or equal to start_time.

end_timestring<date-time>The end of the time interval (end time excluded) used to calculate results over. If unspecified, defaults to the current time if the Experiment is still running, otherwise defaults to the time the experiment was last active. The end time will be rounded to the largest time modulo 5 minutes smaller or equal to end_time. The end_time in the response may be earlier than requested if fresher results are not available yet. In this case, the results will continue to calculate in the background and subsequent requests will eventually return the full results.

browserstringBrowser to segment results by. This parameter must not be sent with any other segmentation parameters, i.e. any parameters in [device, source, attribute_id, attribute_value].

devicestringDevice to segment results by. This parameter must not be sent with any other segmentation parameters, i.e. any parameters in [browser, source, attribute_id, attribute_value].

sourcestringSource to segment results by. This parameter must not be sent with any other segmentation parameters, i.e. any parameters in [browser, device, attribute_id, attribute_value]. Campaign: Contains users that arrive on a URL containing a 'utm_campaign,' 'utm_source,' 'gclid,' or 'otm_source' query parameter. If the URL contains one of these parameters, the visitor will count as "Campaign" traffic even if they arrived through search. Direct: Includes all users who do not have any external referrer in their URL. Referral: Includes all users that come from another URL that doesn't count as Campaign.

attribute_idinteger<int64>ID of the attribute to segment results by. Requests containing attribute_id will return the results for all visitors that have attribute_value for the attribute represented by attribute_id. If present, the attribute_value parameter must also be present, and it cannot be sent with any other segmentation parameters, i.e. any parameters in [browser, device, source].

attribute_valuestringUTF-8 encoded value correlating to attribute_id. If present, the attribute_id parameter must also be present. This parameter also requires attribute_id to be set, and cannot be sent with any other segmentation parameters, i.e. any parameters in [browser, device, source].

segment_conditionsstring(BETA) A string representation of a JSON Segment Conditions Expression. This parameter can be either URL-escaped stringified JSON or Base64-encoded stringified JSON using URL-safe alphabet (preferred). Segment Conditions Expressions consist of Logical Expressions and Match Expressions. Logical Expressions are represented as an array of the format [, ...], where the supported operators are "and", "or" and "not". Match Expressions are represented as an object of the format {"attribute_id": <attribute_id>, "attribute_value": [, "match_type": <match_type>]}, where supported values for match_type are "exact" match type will match only an exact string match between "value" string and the attribute value. "substring" match type will match if "value" is a substring of the attribute value. "prefix" match type will match if "value" is a string prefix of the attribute value. "regex" match type will match if "value" is a regular expression match for the attribute value. The default match_type is "exact".
